Up to 50 percent of the precursor chemicals used to produce this high-performance copolyester elastomer (aka TPC or COPE) is derived from rapeseed oil. The elastomer is strong and flexible. It offers good resistance against UV light and withstands short-term heat exposure at temperatures up to around 200°C.
It is used as an alternative to more traditional thermosetting rubbers for automotive interiors, sports equipment, furniture, and consumer electronics. It’s also used for a baking liner that can withstand oven temperatures.
It can be processed by injection moulding and extrusion, and it is also well suited for overmoulding of other plastics. There is a range of different grades with hardnesses ranging from 40 to 70 Shore D. The material has a silver Cradle to Cradle® certification and the percentage of renewable content depends on the grade. New biochemical processes will soon allow the renewable content to be increased to 73 percent. Product name is Arnitel® ECO.
You get four samples with hardnesses Shore D34, D45, D55, and D65. See the product picture.
