CASE STUDY: VERSAFLEX™ OM TPES THE CHALLENGE Millions of people of all ages play video games. THE SOLUTION While researching other possibilities online, the company found Avient and requested additional information on its thermoplastic elastomers (TPEs). Additionally, compared to silicone rubber, the TPE is easier and faster to process, as it requires no pre-mixing, curing or adhesives.
