About rubber cork cork rubber material with various nitrile rubber and 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. The main technical indicators: Product Category: nitrile product color: natural color, black, red, gray, brown. Tensile strength: not less than 2.0MPa Moulded cut type not less than 1.47MPa Name: Rubber softwood species: oak bark Apparent density: 300 / gm3 flexural strength: 150mpa moisture content: 0.5% Hardness (Shore A): 55- 70 (middle) 70-85 (hard) Density (g / cm3): ≤0.9 (middle) ≤1.05 (hard) Tensile strength: (kg / cm2) ≥15 (in) ≥20 (hard) compression :( % 300psi) 15-30 (in) 10-20 (hard) Compressive Strength (Min): 28kg / cm2 pressure within the anti- (Max): 3.5kgf / cm2 Operating temperature: -40 ~ + 150 ℃ special features: corrosion for: tailor, washing machines, large and small motors, automobiles, motorcycles, tractors, aircraft, ships, and oil pipelines, transformers, electrical equipment and devices. It is low, a new requirement under the pressure of high-grade static sealing materials. And a general seal plate is different, it is easier to cut, no loss of mold, high-volume products can be molded directly from.
