Our design team created a formulation modified for the supplier’s specific processing environment. Finally, the material was formulated to mimic the plush look and dry feel of leather. CORE™ VBX Series Vinyl Powder formulations provide superior haptics and aesthetics for a variety of automotive interior parts.

CASE STUDY: MAXXAM™ POLYOLEFIN FORMULATIONS NEW MATERIAL FOR PRECISELY ENGINEERED VEHICLE Challe nge Accepted. Christoph Wallner (Unit Head, DENSO Europe), throughout the challenging development and fine tuning of the formulation. Avient engineered a new customized formulation for the part, which provided both the processability required for extremely short cycle injection-compression molding, as well as including an additive to stabilize the material when in contact with copper.

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.
