Sealing rings made of PNBP special rubber are excellent in oil resistance, high and low temperature resistance, wear resistance, ozone resistance, tear resistance, and excellent wear resistance in strong acid and alkali media. They can be widely used in aerospace, chemical, petroleum, Metallurgy, electronics and other industries to create a variety of oil seals and seals. It is understood that the chemical composition contained in the refrigerant is highly corrosive to the general sealing material. After the PNBP special rubber is used as the sealing material, the cooling effect is significantly improved. At a temperature of 120 degrees Celsius, the volumetric expansion rate of the material far exceeds industry standards, and has many advantages such as environmental protection and energy saving.
PNBR special rubber refrigerant seal preferred
Recently, the Tailong Special Rubber Development Center in Jixi City, Heilongjiang Province has developed refrigerant rubber seals, in which PNBR is the preferred material.
