Footwear Knowledge Introduction Of Shoe Rubber

< p > < a target= "_blank" href= "//www.sjfzxm.com/" > shoes < /a > rubber mainly includes three kinds of natural rubber, synthetic rubber and general rubber.

< /p >

< p > 1, < a href= "//www.sjfzxm.com/news/" > Natural Rubber < /a >: natural rubber mainly comes from the three leaf rubber tree. When the epidermis of the rubber tree is cut, it will flow out of the milk white juice, called latex.

Latex is obtained by condensation, washing, molding and drying.

< /p >

< p > 2, synthetic rubber: it is made by synthetic method. Different types of rubber can be synthesized from different raw materials (monomer).

< /p >

< p > 3, general rubber: refers to some or all of the rubber species used instead of natural rubber, such as styrene butadiene rubber, butadiene rubber, isoprene rubber, etc., mainly used for making tires and general industrial rubber products.

General rubber has a large demand and is the main type of synthetic rubber.

< /p >

< p > (1) styrene butadiene rubber: styrene butadiene rubber is obtained from copolymerization of butadiene and styrene. It is the most widely used synthetic rubber. It has latex, styrene butadiene rubber and thermoplastic rubber (SBS).

< /p >

< p > (2) CIS polybutadiene: butadiene is obtained by solution polymerization. CIS has excellent cold resistance, wear resistance and elasticity, and also has good aging resistance.

CIS polybutadiene is mostly used for tire production, and a small part is used for making cold resistant products, cushioning materials, adhesive tape, rubber shoes and so on.

The disadvantages of CIS are tear resistance and wet skid resistance.

< /p >

< p > (3) isoprene rubber: isoprene rubber is the abbreviation of polyisoprene rubber and is produced by solution polymerization.

Isoprene rubber, like natural rubber, has good elasticity and abrasion resistance, excellent heat resistance and good chemical stability.

The strength of isoprene rubber raw rubber (before processing) is significantly lower than that of natural rubber, but its quality uniformity and processability are better than those of natural rubber.

Isoprene rubber can replace natural rubber to produce truck tyres and off-road tires, and can also be used to produce various rubber products.

< p > (4) isopropyl rubber: < a href= "//www.sjfzxm.com/news/index_c.asp" > isopropyl rubber < /a > with ethylene and propylene as the main raw materials, aging resistance, electrical insulation and ozone resistance are outstanding.

Isopropyl rubber can be filled with oil and carbon black in large quantities. The price of the products is low, the chemical stability of isopropyl rubber is good, and its wear resistance, elasticity, oil resistance and styrene butadiene rubber are close.

The use of isopropyl rubber is very extensive. It can be used as tire sidewall, rubber strip and inner tube as well as auto parts. It can also be used as electric wire, cable sheath and high voltage and extra high voltage insulation materials.

It can also produce light colored products such as rubber shoes, sanitary products, etc. < /p >

< p > (5) < a href= "//www.sjfzxm.com" > chloroprene rubber < /a >: it is made from chloroprene as main raw material by homopolymerization or a small amount of other monomers copolymerization.

If the tensile strength is high, heat resistance, light resistance and aging resistance are excellent, the oil resistance is better than natural rubber, styrene butadiene rubber and butadiene rubber.

It has strong flammability and excellent resistance to flame retardancy. Its chemical stability is high and its water resistance is good.

The disadvantages of neoprene are electrical insulation and poor cold resistance. Raw rubber is unstable during storage.

Neoprene is widely used, such as wrapping materials for pport belts and pmission belts, wires and cables, making oil resistant hoses, washers and chemical resistant equipment liners.
