TARGET APPLICATIONS Excelite IM chemical foaming additives (CFAs) are engineered for a wide range of injection molded polymers: olefins, PVC, polystyrene, PC/ABS and high heat applications. PP, PE, PS, PVC No Good Foam PP Better, larger cells with lower cell density in standard IM processes; suitable for cell nucleation in structural foam processing PP, PE, PS, PVC Yes Better FA-110 Best cell structure with higher cell density; provides better structural integrity and lower density in standard IM processes PP, PE, PS, PVC Yes Best KEY CHARACTERISTICS Excelite IM formulations provide injection molders with: • Material density and weight reduction • High concentration of active CFA • Improved distribution of CFA into polymer matrix • High cell density with tight cell structure • Control over consistency and accuracy • Reduced sink marks • Ability to improve flow of material • Cycle time reduction • Improved dimensional stability • Improved thermal insulation EXCELITE IM – PRODUCT FORMULATIONS www.avient.com Copyright © 2020, Avient Corporation.

Versollan™ Thermoplastic Elastomers achieved excellent adhesion and improved aesthetics and usability for compartment cover Versollan™ TPEs  were able to provide good adhesion to PCTG and a comfortable, ergonomic grip for a compression controller housing grip Guide to overmolding material selection, part and mold design, material handling and preparation, TPE injection molding, processing, maximizing adhesion and troubleshooting for GLS™ TPEs

Traditional vulcanized rubber products require application of adhesives to bond to the closure, and this adhesive bond has a greater potential for failure than the chemical bond formed between a TPE and  polymer substrate. The adhesive is also an additional component of the container system that must be evaluated for compatibility before use.

The company tried several TPE grades, hoping to find a material that would eliminate the adhesion problem while providing comparable softness to silicone. The manufacturer worked with Avient to formulate a custom Versaflex™ TPE that featured a low durometer with excellent resistance to adhesion (sticking). Armed with a new specialty TPE solution, the medical manufacturer handled gasket adhesion with a material that outperformed that not only silicone, but also conventional TPEs.

Furthermore, Avient’s technical team helped achieve a surface finish that would allow for a strong bond with an adhesive backing and recommended suitable adhesives to achieve optimal bonding of the materials. Beyond grip, the non-abrasive material doesn’t peel up thanks to a durable bond with the adhesive backing, giving customers a reliable solution that eliminates the problem of a slippery surface.

These formulations have low shrinkage and adhesion, high abrasion resistance and stiffness, and good processing speeds.  Non-phthalate PVC colorants are also available.
