Product Description:

1. Description of Rubber:

Natural rubber is a kind of polyisoprene as the main component of natural high molecular compound, its composition in 91% ~ 94% is the rubber hydrocarbon(polyisoprene), the protein, fatty acid, carbohydrate, ash and other non rubber substance. Natural rubber is the most widely used general rubber..


2. Main features of Oil Seal:

1) high elasticity, according to the formula, the elastic can reach 80% of the maximum.

2) high elongation, the maximum can reach more than 1000%.

3) the elastic modulus and the shear modulus is low, than some rigid substances such as iron and steel and other low much.

4) cold resistant, the glass transition temperature of minus 72 degrees..


3. Rubber Images:

Natural Rubber high elongation, cold resistant,  the elastic modulus and the shear modulus is low

4. Rubber Application:

Rubber elasticity, good insulation, impermeability and plasticity characteristics of natural rubber, and through the mix after appropriate treatment also has oil resistance, acid and alkali resistance, heat resistance, cold resistance, pressure resistance, wear resistance and other properties, therefore, has the widespread use, mainly used for automobile, machinery, industrial etc. industry as a shock, sealing parts.

Q:What's the difference between asphalt oil and rubber oil?
Yes, there are many plastic pipes on the roof, and the water around the pipe needs asphalt oil!Coal pitch is a dark liquid with a volume density of 1.25 to 1.35g/cm3 at room temperature (bitumen is liquid, not solid, although it looks solid
Q:Can three yuan ethylene propylene rubber (EPDM) be used in food production? Contact with liquid food ingredients?
Yes, but when choosing ingredients and accelerators, do not use M/DM and other pungent odors, which are rather heavy and bitter.
Q:Which material has the most slippery soles?
To sum up: rubber bottom and bottom Dichotomanthes toughness, better wear antiskid effect. If you want to buy anti-skid shoes, choose shoes should be knocked on the knock, the best flexibility, if only the lines are deep, and the soles of the material is very hard, then still not slip. Similarly, the density is not slippery tendon end.
Q:How do various kinds of rubber come from petroleum processing?
Petroleum cracking naphtha, naphtha is mainly used to produce ethylene, the by-product is butadiene,General purpose rubber is made from butadiene polymerization
Q:Is the basketball shoe with rubber base MD suitable for playing outfield?
Synthetic rubber is also divided into wear-resistant rubber, environmental protection rubber, air rubber, viscous rubber, hard rubber, carbon rubber.(1) wear resistant rubber: wear resistance and toughness of wear-resistant rubber are very good, so it is very durable, this kind of rubber material is usually used on the big bottom of tennis shoes.(2) environmental protection rubber: also known as recycled rubber, this rubber outsole contains up to 10% recycled rubber, the main purpose is for environmental protection.(3) air rubber: Rubber contains air, has a certain shock absorption function, but not very wear-resistant, not widely used.(4) viscous rubber: sticky rubber is characterized by good flexibility, and very slippery, generally used in indoor sports shoes.(5) hard rubber: hard rubber is the most comprehensive rubber in the outsole rubber. It is tough, slippery and very wear-resistant. It is also widely used. Multifunctional shoes and basketball shoes are mostly made of this kind of rubber.(6) adding carbon rubber: adding the carbon in the ordinary rubber material, the rubber is more durable, mostly using the rubber shoes, and will leave a BRS letter in front part of shoes soles, to use carbon rubber outsole.
Q:What are the functional differences between plastic and rubber?
Plastic materials (LC plastic raw materials wholesale, high temperature resistant plastic material, PPS, LCP, PET, PA, PES plastic raw materials suppliers): the main ingredient is resin, is made of polymer resin as main ingredients into a variety of auxiliary material or adding agent, at a certain temperature, with plastic and motor can be under pressure molded into shape and maintain the same shape of material under certain conditions;
Q:Colorful cars are mainly made of plastic, rubber and other materials?
The most essential difference lies in the plastics and rubber plastic deformation occurs in plastic deformation, while the rubber is elastic deformation. In other words, not easy to restore the original state of plastic deformation, and the rubber is relatively much easier. The elastic plastic is very small, usually less than 100%, while the rubber can reach 1000% or more plastic. In the vast majority of molding forming process of finished products is finished; and the rubber molding process after the curing process is needed.
Q:What are the materials for the optical fiber sheath?
Better elasticity should be TPU material.
Q:What material is Buna-N?
BUNA is a brand of foreign Buna, Russia now used more it has two kinds of structure of a BUNA_S (the equivalent of domestic butadiene rubber (BUNA_N) is China's Ding Qingjiao).
Q:What are the raw materials for rubber products?
Rubber shaft roller: all kinds of plastic shaft, printing rubber roller, printing and dyeing rubber roll, paper, rubber roll, etc..Cable wires: all kinds of cables and wires made of rubber.Rubber shoes: sports shoes, labor shoes, light shoes, travel shoes, waterproof shoes, special shoes for labor protection.Rubber parts and accessories: seals, shock absorber, cushion, oil seals and other aircraft, tanks, cars, tractors, construction machinery, warships, cameras, washing machines, electronic watches and other rubber parts and accessories.Rubber ball: basketball, volleyball, rubber rubber rubber rubber ball, water polo, wall toys, children ball etc..Plywood: sponge rubber, rubber sheet, rubber sheet, rubber cloth, rubber and other hard grooves.
