Rubberized Cork Sheets & Gaskets

Cork when compressed there is no lateral spread and when load is released it has excellent recovery. On the other hand Rubber has excellent flowing characteristics and ability to withstand high vacuum. Thus the combination yields an excellent gasketing material which is compressibility of cork combined with the resilience and mechanical strength of rubber – Rubberized Cork.

Cork with any of rubber like natural, nitrile, Neoprene, silicone & EPDM

Attributes of Rubberized Cork

  1. Very resilient to oils
  2. Excellent thermal and sound insulation properties.
  3. Low compression set
  4. Substitute for Woolen Felt, Plastics & ordinary rubber.
  • It can be used as gaskets for oil chambers, valve covers, sumps, pumps, electrical industries like transformers, switchgears, immersed starters, etc.
  • Can be used until 120*C.

Plain Cork Sheets:

  • Cork cells are made with walls of a strong resin substance that is flexible but will not stretch. Trapped inside each cell is a pocket of air (90% by volume). Under pressure the air is squeezed which maintains the counter pressure until force is released.
  • Cork sheets are mainly used as linings of bottle stoppers, glass polishing in the glass industry, clutch facings, brake liners and anti-vibration slabs & foundation blocks.
