??Xinhua Xu rubber material introduction

??The main rubber material as follows:

??(1) FKM: high temperature resistance, in -30 ? - + 250 ? environments, resistant to strong oxidants, oil, acid and alkali. Typically used for high temperature, high vacuum and high-pressure environments, suitable for oil environment. Due to a variety of excellent performance, fluorine rubber is widely used in petroleum, chemical, aviation, aerospace and other sectors.

??(2) silicone rubber: has outstanding resistance to high temperature performance, -70 ? - to maintain a good use of flexibility within the temperature range of + 260 ?, and there is resistance to ozone, weathering, etc., should as a heat sealing machine liner. In the absence of any toxic can make insulation, insulation products and medical rubber products.

??(3) nitrile rubber: has excellent oil and aromatic solvents such as performance, but intolerance ketones, esters and chlorinated by other media, and therefore the oil seal products in order to use nitrile rubber based.

??(4) Neoprene: good oil resistance, solvent resistance, chemical media and other properties, but the impatience of aromatic oil, which is characterized by selling days Hou aging and ozone aging excellent performance. Production of color experience usually make doors and windows sealed neoprene diaphragm and the general vacuum and sealing products;

??(5) EPDM: good temperature resistance, a weathering and aging properties of ozone, usually doors and windows sealed, the most widely used in the automotive industry.
