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..

- Q:What is rubber damping material?
- Butyl rubber, butyl bromide and butyl chloride are the main ones!! Need to design, sell rubber products, can find me!
- Q:Do the rubber mold steel mold and what material good, now with Luo No. 12 steel sticking seriously?
- Adding rubber powder release agent in the formulation, proportion of 0.6-0.9%, the price of only a few thousand dollars a ton. The utility model can effectively solve the difficult problem of demoulding of rubber products.
- Q:Plastic material is rubber or oil?
- Plastic and rubber are two different polymer materials, they are polymers. Two kinds of polymer materials are usually small molecules obtained from petroleum cracking synthesized by polymerization. Such as ethylene polyethylene, polyethylene is a plastic;
- Q:Is EVA material good for sole or good for rubber?Which is more wearable?
- PU: polymer polyurethane synthetic material, often used for basketball and tennis shoes in the bottom, also can be directly used in casual shoes outsole. Advantages: density, high hardness, wear resistance, good flexibility, good oxidation resistance, corrosion is not conducive to environmental protection, easy to fold. Disadvantages: strong water absorption, easy, easy to turn yellow the fracture elongation rate, poor water resistance, bottom perishable.
- Q:What material is FKM and what's the difference from FPM?
- The introduction of fluorine atoms with rubber excellent heat resistance, oxidation resistance, oil resistance, corrosion resistance and ageing resistance, has been widely used in the fields of aerospace, aviation, automobile, petroleum and household appliances, is a key material in the defense industry can not be replaced.
- Q:Which is better, oak or PVC?
- Solid wood cabinet: two degree dry oak is used as raw material. Rubber wood is mainly produced in Southeast Asia, the material has natural lines of clear texture, red, green and white appearance, fine lines of wood. After a unified anti-corrosion, vacuum, non-toxic drying treatment, optimized by the machine forming, the use of high-quality paint, after several days, repeatedly sprayed surface, repair, grinding. The finished solid wood cabinet has a smooth surface, hard wood, strong body, good waterproof performance, and low expansion and no deformation. 2, PVC foaming cabinet: basic material non absorbent, swollen, no deformation, which belongs to the chemical plate, easy to open, in the same raw materials in the high cost of bathroom cabinet. The disadvantage is that the material is partial soft, afraid of high temperature, variable color, etc.. On the market there are several kinds of bathroom cabinet plate, but the high-end products are mostly made of wood, because of its good waterproof performance, seepage deformation, low expansion advantages such as the existence of the mainstream trend of bathroom cabinet bathroom cabinet plate is the future. Solid wood bathroom cabinets generally choose oak as the base material is better.
- 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 kind of material can inhibit the swelling of rubber?
- No. Impossible。
- Q:Soles of the material, good or bad rubber parts, and some will crack, and some will not
- (1): all kinds of sports shoes for ordinary rubber outsole; advantages: good abrasion resistance, anti slip, flexible, easy to break, good softness, good stability, extension and shrinkage, good hardness and good bending. Disadvantages: heavy weight, easy to spit cream (quality problems), not easy to corrosion (environmental issues)(2) PU: synthetic material of macromolecule polyurethane, often be used at basketball, tennis shoes bottom, also can be used at recreational shoe outsole directly. Advantages: density, high hardness, wear resistance, good flexibility, good oxidation resistance, corrosion is not conducive to environmental protection, easy to fold. Disadvantages: strong water absorption, Yi Bianhuang, easy fracture, poor elongation, water resistance, easy to rot at the bottom.(3) EVA: vinyl acetate copolymer, high polymer material. Used to jog, walk, leisure shoes, foot training shoes. Advantages: light, flexible, flexible and difficult to wrinkle. It has excellent coloring and is suitable for all kinds of climates. Disadvantages: easy to absorb water, not easy to corrosion, adverse environmental protection, easy to dirty.
- Q:What material is silicone?
- The role of silica gel is to use its own plasticity to fill these small pits, and the silicone itself is a good conductor of heat, so that it can improve the cooling performance of the machine.
