Heatart – Heat resistant rubber sheets

Heat resistant rubber sheets are made of EPDM or blend of EPDM with IIR quality, recomanded for application with temperature more than 110°C up  to 150°C . Resistant to ozone and ageing factors.

Rubber sheets based on blend of EPDM and  IIR

This refers to products based on ethylene-propylene terpolymers and butyl rubber blends that feature very good physical-mechanical properties; they are suitable for use in high temperature conditions and for exposure to ozone and weathering factors.
