MAXSIL MBSR oil and petrol resistant rubber mix

MAXSIL MBSR oil and petrol resistant rubber mix

MAXSIL MBSR oil and petrol resistant rubber mix is based on methylvinylsiloxane rubber and is produced in two grades A and B. Both rubber mix grades can be produced with and without added curing agent. Working temperature range is from -60°С to +200°C.

Grade A rubber mix is intended for extrusion processing for wire and cable insulation, manufacture of electrical insulating tubes, profiles for various purposes.

Grade B rubber mix is intended for manufacture of molded products: seals, gaskets, O-rings, insulators, etc
