Pawtucket, Rhode Island -- Teknor Apex has introduced an ultra-soft medical elastomer gel in its Medalist series. Although its properties in service are similar to a gel, the material is supplied in free-flowing pellets and processes on normal equipment. The material is transparent and based on a a standard hydrogenated styrenic block copolymer
Teknor said its latests grade, Medalist MD-447, is so ultra-soft that it could not be measured accurately on the Shore A hardness scale used for other Medalist elastomers, the softest of which has a Shore A rating of 5. Subjected to the Shore OO test for ultra-soft materials, the new compound has a rating of 25.
The new compound avoids handling problems sometimes posed by exceedingly soft materials in pellet form, according to Lisa Charno, medical market manager. â€œTeknor Apex has considerable experience with gel elastomers used commercially in non-medical applications,â€ Charno said. â€œWe applied that experience to formulate a gel that achieves new levels of softness yet flows freely in pellet form and is readily processed in standard injection moulding machines.â€
Teknor said, "Medalist MD-447 is free of latex, phthalates, or animal-derived components, and complies with FDA, California Proposition 65, CONEG, and REACH requirements for medical applications."
