Advantages and Disadvantages of Low Temperature Resistant Single Ball Rubber Joints
Gongyi HuanZhong Pipeline Equipment Co., Ltd. is specialized in the production of the development of various cold resistant rubber joints, the low temperature resistance rubber connector has been exported worldwide, especially in the extreme low temperature regions our products of cold resistant rubber joints can still maintain great scalability and high flexibility, ensuring the normal pipeline various compensation, shock and noise reduction.
Low temperature resistant silicone rubber refers to the operating temperature in silicon rubber is - 100 DEG C, the destruction of the regularity of the dimethyl siloxane structure, greatly reducing the crystallization temperature of polymers, which extended silica gel temperature to - 100 DEG C.
Advantages and disadvantages:
1. Advantages: compression permanent deformation, wide range of working temperature, oxidation, weathering, shock and moisture resistance with good electrical insulation properties, low temperature resistance, resistance to ablation and radiation.
2. Disadvantages: with increase of the content of phenyl, the rigidity of the molecular chain of silicon rubber gradually increasing , and silicone rubber cold resistant properties gradually decreased, but with the increasing content of phenyl the vulcanizate of flame resistance and radiation resistance improved.
Low temperature resistant fluorine rubber, is the mixture of tetrafluoroethylene (TFE) and perfluoroalkyl vinyl ether (PAVE) copolymer. , according to the structure of the polymer monomer structure of different dosage, the polymerization monomer PAVE in the polymer chain is usually between 20% to 40% molar ratio.
