Cesa™ Scratch & Mar Resistance Additives Cesa™ Scratch & Mar Resistance Additives are customized solutions enabling manufacturers to produce products that better maintain their finished quality. Cesa Scratch & Mar Resistance Additives are proven compatible across a wide range of polymers, and can be used in a variety of processes, including extrusion, injection molding, blow molding or thermoforming. PRODUCT BULLETIN KEY CHARACTERISTICS • Enhances resistance to scratching, abrasion, and surface blemishes • Keeps products looking newer, longer • Improves perceived quality • Provides a reduction in surface friction and in sticking between parts • Tested and proven compatible across a wide range of polymers and processes—especially successful with polyolefins MARKETS AND APPLICATIONS Cesa Scratch & Mar Resistance Additives give the extra protection needed for many applications, including those that experience daily surface abrasion.

Mevopur™ Healthcare Functional Additives Antistatic Additive APPLICATION BULLETIN Plastics often undergo charge build-up, which can lead to handling problems and electrical discharges. The Mevopur™ Healthcare Functional Additives portfolio includes antistatic additives that reduce the surface resistivity of polymers and the issues caused by electrostatic charges.

PRODUCT BULLETIN Silcosperse™ Additive Dispersions Flame Retardants Silcosperse™ Additive Dispersions for flame retardants that allow manufacturers to design with increased confidence for critical flame and smoke applications. These silicone additive solutions create a char or gas that reduces oxygen at the source of flame, leading to components that become self-extinguishing. Using Silcosperse flame retardant additives ensures that today’s stringent building safety codes and other regulations are met.

Cesa™ Fiber Additives for Heat Preservation TECHNICAL BULLETIN Avient’s new generation of heat-preservation additive formulations for fiber and textile applications are developed to help brands more easily meet demands for lightweight and comfortable winter clothing, sportswear and bedding. Fabrics made with Cesa™ Fiber Additives for heat preservation can absorb more heat than untreated textile when exposed to simulated sunlight with the wavelength from 320 to 1100nm.

Cesa™ Fiber Additives for stain resistance efficacy are non-fluorine additive concentrates developed for incorporation in the yarn during extrusion. Color can be added to the additive in a combination masterbatch allowing for both color and stain resistance efficacy to be integrated into the yarn during the spin-dyeing (dope-dyeing) process. The additive concentrates are also formulated to not interfere with over-dyeing, preserving the stain resistance effectiveness of bath- dyed and piece-dyed yarns and textiles containing our stain-resistant solution.
