Apex Company's Medalist MD-447 is a
transparent medical elastomer gel available in free-flowing pellets for comfort
in skin-contact and other sensitive applications requiring molded-in seal areas
MD-447 is ultra-soft and could not be measured accurately on the Shore A
hardness scale used for other 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. Based on a standard hydrogenated styrenic block
copolymer, Medalist MD-447 is free of latex, phthalates or animal-derived
components, and complies with FDA, CaliforniaProposition 65, CONEG and REACH
requirements for medical applications.
