Cork Rubber Sheet

1. Performance characteristics:

Cork rubber sheet combines the advantages of cork and rubber. It not only retains the aging resistance, oil resistance, low temperature resistance, high friction coefficient, good compression and compression recovery of cork, but also has the high elasticity and compatibility of the rubber used. of tensile strength. The media resistance and other properties of the cork rubber sheet are similar to those of the selected rubber, and the oil resistance is better. In actual use, it is superior to oil-resistant rubber and oil-resistant asbestos. Because the cork rubber sheet does not contain asbestos and other materials, it is an environmentally friendly gasket. Cork rubber sheet has universal value in application, and has unique effects in sealing, anti-vibration, heat insulation, sound absorption, etc., and solves the common "three leaks" problem in mechanical design and mechanical manufacturing.

Experiments have proved that the cork rubber sheet has a very good shockproof effect in terms of use effect, and is convenient and safe to use; it is also non-toxic, odorless, pollution-free, and aging-free; it is wear-resistant, moisture-resistant, oil-resistant and dilute acid-resistant. Under the changes of external environment such as temperature, humidity, pressure, sunlight, air, frost, etc., it will not deform or deteriorate, and its performance is stable. 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.
