CASE STUDY: MAXXAM™ POLYOLEFIN FORMULATIONS NEW MATERIAL FOR PRECISELY ENGINEERED VEHICLE Challe nge Accepted. The technical services team at Avient worked closely with the European material engineering team at DENSO under the lead of Mr. 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.

CUSTOM TPE RESOLVES A STICKY SITUATION FOR CONTACT LENS CONTAINER CASE STUDY: VERSAFLEX™ THERMOPLASTIC ELASTOMERS Challe nge Accepted. The manufacturer produces 7.5 million cases per year, and was using liquid injection molded (LIM) silicone for this part. Because low durometer (softer) material is a requirement for this application, the manufacturer considered a switch to a thermoplastic elastomer (TPE).

Thermoplastic Elastomers | Consumer Products , Packaging Discover how thermoplastic elastomers (TPEs) that withstand oils, solvents, and more are helping brand owners and converters create cosmetic packaging that lasts.

Cesa™ Stat Antistatic Additives Cesa™ Stat Antistatic Additives control the buildup of static charges in thermoplastic parts, enabling them to dissipate by absorbing and ionizing moisture from the air, which forms a conductive path for surface static charges. This static buildup can then cause the resulting parts, film or sheet to cling to one another, or stick to the mold or tool. These static charges can also remain in parts well after production, causing them to attract and collect oppositely charged dust—on an automotive dashboard, for example—or creating unwanted charges on the surface of electrical equipment.

COLORWORKS™ ColorMatrix Select is part of a package of color focused design services and resource available from Avient. Since pioneering the development of liquid color dispersions in the 1970s, ColorMatrix is now a leading innovation brand in advanced liquid colorants for thermoplastic applications. Technical Support Services Our team of technical service engineers are located globally to provide full training and manufacturing support.
