Plastic Additives

Plastic Additives

Enhance plastics performance, products, and processes

Our premier polymer additives are suitable for all types of plastics, plastic products, processes, and end-use markets. We’ve developed multiple polymer families for diverse applications, such as EPS nucleation, film and sheet antiblocking, PVC lubrication, and mold release. These worldwide-recognized polymers serve as chemical intermediates, compatibilizers, dispersants, scratch-and-mar additives, lubricants, processing aids, and resin modifiers.

  • Optimum EPS cell nucleation

    In EPS production, optimum cell nucleation enables superior finished product properties and performance, including improved density potential, faster prepuff maturation, better foam strength at a given density, faster mold cooling time, and improved molding fusion.

    Our POLYWAX™ polyethylenes are unique materials that enable the formation of the small, uniformly sized cells that promote a better surface finish and lower density of the final product.

    Effective mold release

    From our family of microcrystalline waxes to our PETROLITE™ copolymers and our POLYWAX polyethylenes, our products meet your mold release needs whether used as an internal or external constituent or delivered through blooming, wiping, or spraying. 

    Enhance mold release attributes further with our functionalized polymer families, including CERAMER™ polymers, VYBAR™ polymers, DIAX™ polymers; UNICID™ acids, UNILIN™ alcohols, and UNITHOX™ ethoxylates.

    Efficient plastics lubrication

    Our CERAMER 67 polymer offers excellent internal lubrication for rigid PVC applications at loadings significantly lower than competitive oxidized lubricant grades. Our POLYWAX polyethylene family of polymers is available for many other plastics lubrication requirements.

    Superior antiblock applications

    Our antiblocking agents range from refined petroleum-derived microcrystalline waxes to specialty low molecular weight, olefin-based polymers having a very linear structure and narrow molecular weight distribution. 

    Depending on the application, one or more of the following polymer families can be the appropriate solution to your antiblocking needs: POLYWAX polymers; PETROLITE polymers and copolymers; and our BE SQUARE™ waxes.

    You can use antiblocking agents for a wide variety of applications, including nonclumping and free flow of pellets during packaging, shipping, and transfer; control of surface tackiness of injection, rotational, and blow-molded parts; and easy separation between layers of stacked sheets and wound film rolls.
