Top 10 Silicone Additives Manufacturers in the World for Polymer Processing

Introduction: The Role of Silicone Additives in Polymer Processing
Silicone additives are widely used as processing aids and functional modifiers in polymer manufacturing to regulate melt behavior, improve surface properties, and enhance processing stability under high-throughput production conditions.
In thermoplastic processing environments such as extrusion, injection molding, film blowing, and compounding, polymers are often subjected to high shear stress and elevated temperatures. These conditions can lead to common processing challenges, including unstable melt flow, surface defects (such as melt fracture and sharkskin), die build-up, and inconsistent product quality.
Silicone additives are engineered to address these interfacial and rheological limitations by reducing polymer–metal friction, improving lubrication at the melt interface, and stabilizing flow behavior during processing. As a result, they contribute to more efficient production operations and more consistent final-product performance.
They are widely applied across major polymer systems, including polyolefins (PE, PP, LLDPE, HDPE, EVA), PVC compounds, thermoplastic elastomers (TPE, TPU, TPO, TPV), and engineering plastics (ABS, PC, PA/Nylon, PBT, PET, PPS, POM, and PMMA).
From a processing standpoint, silicone additives are used in extrusion, injection molding, film blowing, and compounding processes, where they help stabilize melt rheology, reduce interfacial friction, and minimize surface- and die-related defects under continuous or high-speed operating conditions.
End-use applications include wire and cable systems, automotive interior components, footwear materials, pipes, flexible packaging, coatings, paints, fibers, and a wide range of engineered and modified plastic products.
With increasing industry emphasis on higher productivity, tighter quality control, reduced scrap rates, and improved material sustainability, silicone additives are no longer viewed as simple processing aids. Instead, they are increasingly integrated as functional formulation components within polymer system design, contributing directly to both processing efficiency and final-product performance.
As a result, silicone additive manufacturers have become key technology partners throughout the global polymer value chain.
This article highlights the top 10 silicone additive manufacturers worldwide, helping processors identify leading suppliers, technologies, and solutions for polymer processing applications.

What Are Silicone Additives?
Silicone additives—also referred to as silicone-based additives, siloxane additives, or polysiloxane additives—are functional processing aids and performance-enhancing materials typically based on polydimethylsiloxane (PDMS) or modified organosilicon compounds.
They are incorporated at relatively low concentrations (typically 0.1–5%) to improve processability, surface characteristics, and long-term product durability.
Key Performance Functions
• Reducing melt friction and improving flow behavior
• Preventing surface defects such as melt fracture and sharkskin
• Reducing die build-up and minimizing equipment fouling
• Enhancing surface smoothness and tactile properties
• Improving production stability and throughput

Core Chemistry of Silicone Additives
The performance of silicone additives originates from their flexible silicon–oxygen (Si–O) backbone, often functionalized with organic side groups such as methyl.

This unique molecular structure provides:
• Low surface tension for superior lubrication
• High thermal and oxidative stability under demanding processing conditions
• Hydrophobicity that helps protect polymer surfaces from moisture
• Excellent slip and lubricity, reducing shear stress during extrusion and molding
• Chemical inertness and flexibility, enabling compatibility with a wide range of polymers

Types of Modern Silicone Additives
Silicone additives are engineered to meet specific performance requirements depending on molecular weight, functional groups, and polymer architecture. Common industrial forms include silicone fluids (oils), siloxanes, polyether-modified silicones, silicone resins, silicone masterbatches, and silicone powders.

1. Silicone Masterbatch
Silicone masterbatch is a premium pelletized formulation widely used in the polymer industry. The state-of-the-art technology relies on dispersing ultra-high molecular weight (UHMW) siloxane polymers into various thermoplastic carriers (including polyolefins, engineering plastics, and thermoplastic elastomers). Delivered in standard pellet form, it allows clean, precise dosing directly into the thermoplastic matrix during compounding, extrusion, or injection molding. Unlike traditional waxes, fatty acid amides, or low-molecular-weight oils, UHMW silicone masterbatches provide superior surface slippage and mold release while effectively avoiding processing defects like screw slippage.

2. Silicone Fluids (PDMS)
Silicone Fluids (PDMS) are low-to-medium molecular weight, linear, non-reactive silicones characterized by a repetitive silicon-oxygen (-Si-O-) backbone with methyl side groups. In polymer processing, they function primarily as temporary physical processing aids and external lubricants. Due to their high molecular mobility and lack of chemical bonding with the host polymer matrix, they lower melt viscosity and torque but are highly prone to migration, leading to surface exudation, screw slippage, and subsequent paint or printing adhesion failures.

3. Functional Organosilicone Additives
Functional Organosilicone Additives are chemically, or organo-modified silicone copolymers that incorporate reactive or polar functional groups (such as epoxy, amino, carboxy, vinyl, or polyether segments) into the siloxane backbone or chain ends. Unlike conventional PDMS, these additives are molecularly engineered to act as interfacial modifiers and reactive compatibilizers. They reduce interfacial tension and enhance phase adhesion between incompatible components, making them essential for upgrading engineering plastics, boosting the performance of recycled/PCR polymers, and improving filler wetting and dispersion (e.g., halogen-free flame retardants, glass fibers) in multi-component polymer systems.

4. Silicone Powders
Silicone Powders are free-flowing, solid, particulate silicone formulations, often comprised of ultra-high molecular weight (UHMW) siloxane polymers anchored in an inorganic silica core, or three-dimensional spherical silicone resins (e.g., polymethylsilsesquioxane). Engineered as permanent performance modifiers, they are compounded into thermoplastics to provide long-lasting surface enhancements—such as permanent scratch and wear resistance, stable reduction in the Coefficient of Friction (COF), and anti-blocking features—without compromising the substrate's mechanical properties or post-processing paintability.

Powder Coat Booths

For those larger-sized parts, or smaller quantity runs, we have 2 independent powder coat booths and ovens. The quality, durability and affordability of today’s powder coating finishes make this the process of choice for world-class companies.

Powder coating advantages over other forms of coating are many. Materials used in the Powder coating process can be metals and non-metals that come in a multitude of thicknesses, textures, colors, etc. Another of Powder coating’s biggest advantages over conventional coatings is its ability to create finishes in many different textures. Powder Coating Booths allow us the ability to apply these advantages to large products.

Wet Paint Line

Tri-State Fabricators runs a full-service conveyor line for painting. Wet painting can provide protection or decoration to many different part styles. From start to finish, every project is easier to undergo random and point-based inspection by our skilled painting team.

Advantages to our Wet Paint Line are these lines start with product prep and ends with a thorough inspection of a high quality finished product. Our ability to complete large and small projects with a superior finish and doing so in a timely and economical fashion. This passes along the savings in production to our customers. When powder coating ins not an option, our Wet Paint Line gets the job done right the first time.

Wet Paint Booths

When the parts get big and heavy we roll-out our custom paint racks and oversize booth. By utilizing our partnerships with all the major paint brands, we can match virtually any color with wet paint.

The advantages of having access to a Wet Paint Booth are many. Large projects of many different shapes can be loaded into the booth. The Wet Paint Booth offers an environment that is much more controlled than a typical parts painting operation.

Not only are they used because of their controlled environment, but they’re are also advantageous when it comes to applying paint to parts that are needed in industries that require specialty coatings such as medical, aerospace, etc.

Military CARC

Our military forces have some very high standards when it comes to the finish of their vehicles and equipment. From the first pre-treatment step to final coat, it takes a great deal of knowledge and experience to protect the men and women of our armed forces. They deserve only the best, and Tri-State Fabricators provides it.

All of our processes are closely monitored by our staff and management teams. Both of which are highly trained in the processes of metal fabrication and finishing. Tri-State Fabricators’ goal is to always fully satisfy each and every customer, including the military. We will always put a 110% into what we do.

Glass-Bead Blasting

Abrasive media blasting is an excellent way to remove old paint, rust, and increase the paint/powder adhesion. Glass beads produce a much smoother and brighter finish than angular abrasives; leaving the part clean yet without any dimensional change. Chemically inert and environmentally friendly, we can recycle our beads approximately 30 times; making them a more preferred method of metal cleaning or surface finishing.

Advantages to Glass Bead Blasting are many. Glass bead blast media is used when a project is needing rough surfaces need to become smooth for applications of coatings such as paint. It is typically used to clean paint and rust from a product surface without deforming the surface it is being used on. Overall, compared to many other blasting media, Glass Bead Blasting is a very economical choice and those savings are always passed on to our customers.

Part Washing

Tri-State Fabricators utilize a zinc phosphate wash to clean and etch the material to ensure the best paint adhesion possible. The unique design of our 3-stage wash system does the work like a 5-stage. From Cleaning and rinsing to conversion coating and post-treatment, Our Part Washing process is a complete service and works throughout the fabrication service and the finishing service.

Along with the previously mentioned benefits, Curing is a vital chemical reaction that leaves the product finish hard and relatively safe from mild abrasion and aggressive corrosion. This process can be done in more than one way; ambient air-dry or in curing ovens at temps that exceed 240°.

Burn-Off Oven

From fixing paint mistakes (someone else’s of course) to simply cleaning our paint line hooks, our burn-off oven is put to good use. After a quick burn-off, a little clean up, and a fresh coat of paint, your parts will look better than new.

Why does our Burn-Off Oven work so well? Because super heating the air around parts turns the materials into ashes. From paint and powder coatings to rubber and machining oils, high temps do the job without degrading the integrity of the part.

Masking

Masking is a vital part of producing high quality products. We have die-cut masking patterns to protect machined surfaces as well as a wide range of plugs and caps to protect threaded holes and bolts. We provide permanent and temporary masking.

Masking allows the selected sections of a product to be protected from a fabrication or finishing service. This can be with both chemicals when etching and tapes, paints when only finishing just a section of the product. Masking is great in aiding the customization process of a project.

Screen Printing

Screen printing is a photographic process that transfers artwork onto a porous nylon screen which allows colored ink to flow through the screen and be deposited on an aluminum or plastic component. We can generally have just about any design created onto a screen for your parts.

Some of the advantages of Screen Printing are, brand recognition for your business displaying on your products, assembly instructions, product warnings/hazards, etc. Tri-State Fabricators produces Screen Printing of the highest quality so you know it’s durable.

Metal Finishing

Metal Finishing is the art of treating the exterior portion of product, often metal but can also be made of other materials, so that the surface is clean and free of any debris. Then the process of applying coats or either paint of powder coat takes place. This coating process improves the quality of the product in both appearance and resistance to wear and corrosion.

Tri-State Fabricators, Inc., understands that a project typically isn’t complete until a high-quality finish has been added to your product. This is why our painting and powder coating teams continuously inspect the products throughout the Metal Finishing process.
