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..

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.
5. FAQ
We have organized several common questions for our clients，may help you sincerely：
①How about your company？
A world class manufacturer & supplier of Rubber is one of the large scale professional investment casting production bases in China,consisting of both casting foundry forging and machining factory. Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirement.
②How to guarantee the quality of the products？
We have established the international advanced quality management system every link from raw material to final product we have strict quality test; We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.
- Q:What is the difference between TPE material and silicone rubber?
- Silicone rubber is a kind of special rubber, cross-linking has good mechanical strength, wear resistance and high temperature resistance, which belongs to the thermoset rubber, vulcanized after heating when the temperature is too high will not melt, combustion, complete combustion product is water and silica
- Q:What are the important raw materials of synthetic rubber?
- Chloroprene rubber is a chloroprene as the main raw material, made by homopolymerization or copolymerization of small amounts of otherNitrile butadiene rubber is obtained by emulsion polymerization of butadiene and acrylonitrile
- Q:Which is better, oak or PVC?
- Oak: 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.
- Q:Are rubber materials isotropic? Or is it anisotropic?
- Rubber materials are generally amorphous, and even crystalline rubber (such as natural rubber, isoamyl gum, neoprene, etc.), crystallization is also very low, so rubber materials are generally of the same sex
- Q:Compression permanent deformation of rubber material is not the same concept as dimensional stability
- The compression rate of permanent deformation is compressive deformation capacity determination of foaming material and rubber and other soft materials, it relates to the vulcanized rubber and elastic recovery, in particular are generally known height samples, according to the compression rate requirements compressed to a specified height and keep under specified conditions of temperature for a certain time, then lift let the free state under compression, sample response, measuring samples within the time specified in the height, and then through the formula to calculate the compression rate of permanent deformation.
- Q:What's the raw material for making rubber molds? Just rubber
- Rubber mold is one of the most simple method in rapid tooling, is generally used RP silica gel prototype mode, but life is very short, only about 10-30! He has good elasticity and reproduction performance, with silicone rubber mold can be copied without considering the draft, will not affect the dimensional accuracy of segmentation well, not on the die can be directly integralpouring. Then along the parting line for cutting out predetermined mold on it!
- Q:What are cots for?
- Cots are mainly used in paper making, printing and dyeing, printing, grain processing, metallurgy, plastic processing and so on.
- Q:What kind of material does rubber leather paint belong to?
- Rubber paint is widely used in ABS, PVC, PC, PS, and other material and hardware, plastic products, metal spraying special primer, bakelite, wood, ceramics and other products. Spray the product has special soft, smooth, delicate, sensual touch and a rubber like texture and skin feeling, give a person a kind of very happy and feel comfortable. Decorative products to make the effect more noble and elegant, clean and generous, and more show the value of the product.
- Q:How do rubber and nylon die together?
- Put into the mold after vulcanization, vulcanizing machine pressure should be large, 10MPa or more, the temperature should be appropriate, according to the adhesive and rubber formulations vary, and the general temperature is generally at 140 degrees ~150 degrees Celsius
- Q:What's the material on the rubber floor?
- 1, compared with wood: flame retardant, waterproof, antistatic, corrosion resistant, easy to clean2, compared with stone: good elasticity, anti-static, construction is relatively simple, convenient, time-saving and material saving3, and PVC compared to: wear-resistant, anti-skid, environmental protection, and obstruction6, in the sales process, the customer is generally concerned about what is the problem?One is the product quality problems at present: Bonie in the United States and Armstrong.Two is the product price question: the quality is better, will naturally be more expensive. Rubber is generally more expensive than PVC.
