Description

General Purpose Silicone Rubber for Extrusion

5250 Slightly Transparent 8Mpa General Purpose Silicone Rubber for Line and Tube

DESCRIPTION

After the addition of the vulcanizing agent "Double 2, 4," this product can undergo basic processing, and under appropriate technical conditions, does not require a second vulcanization step. The final product exhibits excellent properties such as high and low-temperature resistance, corona and arc resistance, and electrical insulation. It can serve as suitable material for various applications, including electrical wire and cable, jacket rubber tubes, electrical insulator parts, heat-resistant seals, irregularly shaped and foam strips.
