Cork Rubber Sheet
Cork Sheet
Cork sheet is made of clean granulated cork mixed with resin binder, which is compressed to form block, then split into sheets. The sheets have properties of good resilience, good resistance to water, oil and solvents, and good compressibility and so on.
Rubber Cork sheet
Rubber Cork sheet is a compound of cork and rubber made by using granulated cork and synthetic rubber polymer and their assistants. The product has properties of high resilience of rubber and compressibility of cork, so its performance is excellent. It can be used as gaskets of various engines of automobiles,tractors,plants,ships,and pipes petroleum, transformers electric equipment and apparatuses. It is a kind of new type high-grade static sealing materials used to seal low and medium pressure.
