Butyl Gaskets


You are Here:

Butyl has a very low permeability rate and good electrical properties. Butyl Rubber Gaskets is a high quality rubber gasket recognized by leading manufacturer American Seal and Packing. Butyl contains high quality butyl rubber gaskets, seals, and custom butyl products.
Butyl gaskets has high resistance to weather, chemicals and good permeability. The rubber gaskets has bad resistance against petrol and is often used with pond liners.

The advantage of the butyl rubber Gaskets

  • Low Permeability
  • Thermal stability
  • Low temperature resistance
  • Ozone resistance and weather resistance
  • Chemical resistance
  • Electrical resistance
  • Water-absorbent
