Grade Thermoelastolayer TEP 02035-305 K
Specification 2243-003-12741606-2001 Main properties Thermoelastolayer based on polypropylene and ethylene-propylene synthetic rubber (SEPR) is obtained by “dynamic” vulcanization method. It is resistant to copper ions, self-extinguishing, resistant to photooxidation ageing. PurposeApplied as rubber alternative in the making of coating for cables and wires, automotive parts, also in electrotechnics and the production of household appliances.
