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.
Everyone has had the experience of trying to scrape the last of the peanut butter or mayonnaise from the bottom of a glass jar without getting your hand sticky. Inventor Ron Jidmar thinks he has a solution to all of that nonsense with a flexible jar design that can be squeezed with one hand to lift contents from the bottom to the top of a jar or container, leaving the other hand free to scoop the contents out cleanly.
