CUSTOM TPE RESOLVES A STICKY SITUATION FOR CONTACT LENS CONTAINER CASE STUDY: VERSAFLEX™ THERMOPLASTIC ELASTOMERS Challe nge Accepted. THE SOLUTION Avient formulated a custom Versaflex™ TPE that featured a low durometer with excellent resistance to adhesion (sticking). However, before making the decision to switch from silicone to the Versaflex™ material, the company needed to feel confident that it would recoup its capital, which included a $50,000 investment in new tooling, within 12 months.

CESA™ Block Additives Antiblocking PRODUCT SELECTION GUIDE Unmodified film and sheet can adhere, causing problems of separation. The modification of the surface can be achieved without negative impact on the optical properties of the film. CESA Block can be used in thin gauge film applications. 1.844.4AVIENT www.avient.com Copyright © 2022, Avient Corporation.
