Xingtai oil seal is made to order Small make up to tell you The characteristics of rubber products　　1. The rubber molding, after pressure pressing, the cohesion of both by elastomer, cannot be eliminated when molding from, often produce unstable contraction (rubber shrinkage rate, by analysing different difference), after a period of time required, to moderate stability.So when a rubber at the beginning of the design, formula or mould, all need to be careful calculation to cooperate, if not, the size is not stable, easy to produce products products quality is low.　　2. Of hot-melt thermoset rubber elastomer, plastic belong to hot-melt cold setting.Rubber by sulfide species subject, different curing temperature range, its shape is also have quite a gap, even because of climate change, the indoor temperature and humidity.Rubber products production conditions, therefore, need do moderate adjustment at any time, if not, may produce products the quality difference.　　3. Rubber products is conducted by rubber raw material mixer mixing is made after mixing rubber as raw materials, according to the characteristics of rubber products required in rubber mixing and formula design, and set the required product hardness.Product production molding by rubber vulcanizing press molding.After molding, products and flash processing, product surface treatment is smooth without burr.　　4. Rubber aging tests belong to the category of aging test, aging refers to the rubber and rubber products in the processing, storage and use process, due to the combination of internal and external factors causing performance structure change, therefore its use value.Characterized by cracking, tacky, hardening, softening, pulverization, discoloration, mold, etc.

　　Xingtai seal sales Small make up to tell you The classification of the rubber products　　General rubber　　Refers to the part or the whole instead of natural rubber with analysing, such as styrene butadiene rubber, butadiene rubber, isoprene rubber, etc., mainly used in the manufacture of tires and general industrial rubber products.General rubber demand is big, is the main varieties of synthetic rubber.　　Styrene butadiene rubber　　Styrene butadiene rubber is made by copolymerization of styrene butadiene and, is the biggest general synthetic rubber production, have emulsion poly styrene butadiene rubber, butadiene styrene rubber and thermoplastic rubber (SBS).　　Butadiene rubber　　Is made by solution polymerization of butadiene, butadiene rubber has a special excellent cold resistance, abrasion resistance and flexibility, also has good resistance to aging performance.For the most part butadiene rubber used in the production of tires, a few used in the manufacture of cold products, buffering material and adhesive tape, rubber shoes, etc.Butadiene rubber tearing resistance are the shortcomings of a job, wet resistance is not good.　　Isoamyl rubber　　Isoprene rubber is short for polyisoprene rubber, by solution polymerization production.Isoprene rubber and natural rubber, has good elasticity and abrasion resistance, excellent heat resistance and good chemical stability.Isoprene rubber (raw rubber (unprocessed) before strength significantly lower than natural rubber, but the quality uniformity, such as processing performance is better than that of natural rubber.Isoamyl rubber can replac natural rubber manufacturing truck tyre and off-road tires can also be used for the production of various rubber products.　　Ethylene propylene rubber　　Ethylene propylene rubber to ethylene and propylene as the main raw material synthesis, ageing resistance, electric insulation performance and ozone resistance.Ethylene propylene rubber can be a large number of oil filled and filled with carbon black, product prices low, ethylene propylene rubber chemical stability is good, wear resistance, elasticity and oil resistance and styrene butadiene rubber.Ethylene propylene rubber USES is very wide, can be used as a tire side, strip and tube, and auto parts, still can make electrical wiring, cable sheathing, high pressure and ultrahigh pressure of insulating material.Still can make rubber shoes, sanitary products and other light products.　　neoprene　　It was based on chloroprene as the main raw material, through homopolymerization or a small amount of other monomer copolymerization.Such as high tensile strength, heat resistance, good light resistance, aging resistance and oil resistance were superior to natural rubber, butylbenzene rubber, butadiene rubber.With strong flame resistance and excellent resistance to secondary, its high chemical stability, good resistance to water.Neoprene disadvantage is that the electric insulation, cold resistant performance is poorer, raw rubber unstable during storage.Neoprene wide range of USES, such as used to make transportation belt and belt, wire, cable wrapping material, manufacturing oil resistant rubber lining, washer, and resistance to chemical corrosion of equipment.
