Product description

  Mixing rubber silicone (silicone rubber) is made by silicone rubber to the double roller rubber mixing machine or airtight kneading machine gradually add the white carbon black, silicon oil and other additives such as repeatedly refined and synthetic rubber.
The characteristics of the silica gel mixing rubber:
Excellent thermal stability, high and low temperature resistance, can at 60 ℃ ~ + 250 ℃ condition long-term work, ozone resistance, weather resistance and good electric performance, corona resistance, arc, edm is extremely strong, with chemical stability, weathering resistance, radiation resistance, with physiological inertia, permeability is good.
The kinds of silica gel mixing rubber:
Common type, high temperature resistant, low temperature resistant, flame retardant, environmental protection, anti-static type, enhanced, tearing resistance, food grade, spa, etc
The purpose of the silica gel mixing rubber:
Can be widely used in aviation, cable, electronics, electrical, chemical, instrumentation, cement, automobile, construction, food processing, medical equipment and other industries, used for moulding, extrusion machinery such as deep processing   Specification :
