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's the inner lining, please?
- There are inner pipe jacket, such as day, tube, etc.; there are outside the pipe painted, such as large-diameter water pipes. An internally coated steel pipe for corrosive medium fluids replaces the expensive stainless steel pipe.
- Q:What is the density of polyurethane?
- Hard polyurethane coating agent polyether based polyurethane foam density: 0.04 ~ 0.06g/cm3 hard polyurethane foam density: 0.03 ~ 85 0.07g/cm3 polyurethane density of about 1.2g/cm3, no filler generally around 1.1
- Q:Is EVA material good for sole or good for rubber?Which is more wearable?
- PHYLON (MD): two high pressure molding product is EVA, the main ingredient in running shoes, tennis shoes, basketball shoes at the end of the world, but also can be used for casual shoes outsole. Advantages: lightweight, flexible, fine appearance, good softness. Easy cleaning, hardness, density, tensile strength, elongation, tear. Disadvantages: easy to corrosion. The adverse environmental protection, high temperature easy to wrinkle, easy to shrink.
- Q:How much does rubber raw material affect the tire cost?
- With the decline in rubber prices over the past few years, has everyone focused on the "three glue" still has so much influence on the tires? Next, we will take the full steel tire as an example, focusing on the analysis of the change of the proportion of three rubber in a tire. As each tire distribution strategy is different, so I will do from the past few years to waste tires to analyze the experience, according to our more than 900 of scrap steel wire after the decomposition of the proportion of roughly estimated in theory.
- Q:PVC how long does the rubber waterproof finish?
- The setting time of PVC rubber waterproof material has a great deal to do with temperature,1, PVC806 rubber waterproof material, summer 160 degrees, 6 minutes or so began to solidify,2, winter 8 minutes to 9 minutes freezing, generally winter can be 170 degrees, 5-6 minutes, the same can be solidified.
- Q:How do various kinds of rubber come from petroleum processing?
- Naphtha is also a fraction of petroleum cracking, just like gasoline, diesel, aviation kerosene
- Q:What material is that high temperature resistant rubber sealing ring, please?
- Generally silicone rubber, such as pressure cooker, sealing ring all silicone rubber. Depending on your medium and conditions of use.
- Q:What material is silicone?
- According to the size of the pore size, silica gel is divided into large pore silica gel, coarse pore silica gel, B type silica gel and pore silica gel. As a result of pore structure difference, therefore their adsorption performance has respective characteristic. Porous silica has a higher adsorption capacity at high relative humidity, kiselgel in conditions of low relative humidity is higher than the adsorption capacity of porous silica, and silica gel B as pore structure between coarse and fine pored silica gel, the adsorption between coarse and fine pores. Macroporous silica gel is usually used as catalyst carrier, matting agent, toothpaste, abrasive and so on. Therefore, different varieties should be chosen according to different uses.
- Q:What material is FPM?
- FpM is the abbreviation of fluorine rubber.Fluorine rubber can be divided into three basic types: fluorocarbon rubber, fluorosilicone rubber and fluorinated nitrile rubber.
- Q:The main material in the car's seal is rubber. What else is there besides rubber?
- Ethylene propylene rubber accounted in this issue of how many, you need customers to what the quality of the strip, three yuan a best quality EPDM rubber, EPDM rubber can reach 60%, also is more and more strict standards on the use of auto train ship railway etc. These quality requirements.
