General Purpose Grades: GP40 - 80

General purpose silicone rubber applications

The general purpose silicone rubber grades are suitable for complex extruded profiles and mouldings. They are suitable for a wide range of uses including tubing and seals for the food and pharmaceutical industries (F.D.A and W.R.C approved*), and silicone rubber parts in vehicles.

Their physical properties include:

  • Temperature range -65°C to 200°C
  • Heat stabilised parts can withstand short term exposure between 250° C - 300°C

These Rubbers can be supplied pigmented or transparent.
