Rubber, nitrile rubber and cork with various other supporting material from a choice of the finest cork granules. Rubber cork with a higher compression and resilience than normal cork is an excellent sealing material. Product The experiment proved that the use of results, with a very good shock effect, easy to use security; and non-toxic, tasteless, non-polluting, non-aging; can wear, resistant to moisture, oil and acid. Changes in the external environment temperature, humidity, pressure and sunshine, air, frost, no distortion, no deterioration, stable performance. It is low, a new requirement under the pressure of high-grade static sealing gasket material. The machine can be used as seals, play oil, acid, pressure and high-temperature effects. As abrasion parts for conveyor belts and brake pads, etc., we have a good wear resistance. Rubber cork can be used as seismic, shock absorption, sound insulation aspect.
