Cork rubber sheet
First, the performance characteristics:
Cork rubber sheet combines the advantages of cork and rubber, retaining the anti-aging, oil resistance, low temperature resistance, high friction coefficient, good compressibility and compression recovery of cork, and high elasticity and combination of rubber used. Tensile strength. The properties of the cork rubber sheet are similar to those of the selected rubber and have better oil resistance. It is superior to oil resistant rubber and oil resistant asbestos in practical use. Since the cork rubber sheet does not contain asbestos and other materials, it is an environmentally friendly gasket. Cork rubber sheet has universal application value, and has unique use effect in sealing, anti-vibration, heat insulation, sound absorption, etc., and solves the "three leaks" problem that is common in mechanical design and mechanical manufacturing.
Cork rubber board has been proved by experiments to have very good anti-vibration effect, easy to use and safe; and non-toxic, odorless, non-polluting and non-aging; wear-resistant, moisture-resistant, oil-resistant and dilute acid. Under the external environment changes of temperature, humidity, pressure and sunlight, air, frost, etc., it does not deform, does not deteriorate, and has stable performance. It is a new type of high-grade static seal and gasket material under low and medium pressure requirements. Widely used in automobiles, machinery, aircraft, ships, as well as oil pipelines, water pipes, transformers, electrical equipment and devices.
