Excellent Oil Resistance Silicone Rubber Elastic Soft VMQ Compound
Description:
Oil resistant silicone rubber has excellent oil resistance, good processing.Excellent high and low temperature resistance, can be used in the range of -60 ℃ ~ + 220℃ for a long time.It has excellent mechanical properties, good resilience and aging resistance.
Used for manufacturing various kinds of oil-resistant sealing rings, oil seals and so on.
Oil resistant silicone is suitable for fixed installation from power transmission line or portable electric connecting cable, the product has the heat radiation, cold resistant, resistant to acid and alkali and corrosive gas, waterproof properties, such as soft cable structure, the convenient radiation, high temperature electric performance is stable and cold environment, anti-aging performance is outstanding, long service life, widely used in metallurgy,electric power, petrochemical, electronics, automobile manufacturing and other industries.
Used for manufacturing oil-resistant seals, sealing plugs, kitchen utensils, mobile phone keys, gloves, oil-resistant coats, miscellaneous and other oil-resistant products.The disadvantage of ordinary silica gel is that it is not resistant to oil, especially hot oil. Soak in hot oil, it will soon swell and its mechanical properties will be greatly reduced.
Therefore, it hinders the application of silicone rubber in automobile, mechanical equipment and other sealing parts that require both high temperature resistance and oil resistance. In order to meet the performance of oil resistance, domestic manufacturers have developed oil resistance silicone rubber at 260℃ for long-term use.
Features:
Oil resistant silica gel features:
good processing, suitable for ordinary mold pressing,
Shore A hardness of 30~80 degrees, good mechanical properties, resistance to oil, grease,
mineral oil, fuel oil, ASTM test oil, brake fluid, etc. Oil resistant silicone rubber is a kind of organic silicone rubber compound
with a hardness of 30-80 degrees. Peroxide vulcanizing agent was used.
It is suitable for moulding process. Good oil resistance, good resistance to mineral oil, grease, etc.
