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.
It would be very interesting/educational to find a comparison between this elastomer gel and silicone rubber.
Aside from the fact that the elastomer gel is thermoplastic (can be melted and reformed) and silicone is a thermoset material (molded once and your done), I wonder how the gel holds up in other mechanical properties in comparison to silicone rubber.
Design collaboration now includes the entire value chain. From suppliers to customers, purchasing to outside experts, the collaborative design team includes internal and external groups. The design process now stretches across the globe in multiple software formats.
A new high-pressure injection-molding technology produces near-net shape parts with 2-inch-thick walls from high-performance materials like PEEK, PAI, and carbon-filled polymers. Parts show no voids, sinks, or porosity, have more consistent mechanical properties, and are stronger.
