FAQ

What's the difference between natural rubber and three yuan ethylene propylene rubber?
The dielectric properties of natural rubber are a nonpolar substance that is soluble in non-polar solvents and non-polar oils. Natural rubber is not resistant to cyclohexane, gasoline, benzene and other media, non vulcanized rubber can be dissolved in the above medium, vulcanized rubber swelling. Natural rubber insoluble in polar acetone, ethanol, more insoluble in water, resistant to 10% hydrofluoric acid, 20% hydrochloric acid, 30% sulfuric acid, 50% sodium hydroxide and so on.
NR natural rubber manufacturers, who knows Guangdong here, there are manufacturers, a few hair connection is OK
Butadiene styrene rubber (SBR) copolymer of butadiene and styrene. Performance is close to natural rubber, is the largest yield of general-purpose synthetic rubber, characterized by wear resistance, aging resistance and heat resistance, more than natural rubber, texture is more natural rubber uniform. Disadvantages are: low elasticity, anti bending, anti tear performance is poor; the processing performance is poor, especially the poor, low strength self adhesive rubber. Temperature range: about 50 DEG C ~100. Mainly used instead of natural rubber to make tires, rubber sheets, hose, rubber shoes and other general products.
What kind of material does the shockproof rubber cushion usually choose? What's the hardness?
The air tightness of butyl rubber is the best of all the rubber, is its biggest advantage, it is mainly used for tyres, although there are shock absorbing function, but dynamic flex is not ideal.
Aging of rubber parts for automobiles
Automobile rubber parts aging factors are: oxygen, ozone, heat, light, mechanical stress, moisture, oil, other chemicals or radiation, etc.. Attention should be paid to water and oil here:The alternate action of high temperature and oxygen 1. long-term water and in the external environment under the accelerated aging of rubber;2., the oil will penetrate the rubber, so that swelling occurs, rubber performance will be reduced. Therefore, trucks should avoid shock absorption of rubber bushings, oil and diesel in various occasions, including maintenance.
The action of various ingredients in rubber formula
Curing system: vulcanizing agent, accelerator, active agent, anti coke agent,
What kinds of vulcanized rubber do you have?
According to the appearance of rubber: rubber can be divided into solid rubber (also known as dry rubber), emulsion rubber (referred to as latex), liquid rubber and powder rubber four categories.
What is the difference between rubber expansion joint and rubber joint?
A rubber joint is a hollow rubber product used for flexible connections between metal pipes. The flexible joint is also called soft rubber pipe joints, rubber joints, soft rubber joints, flexible joints, high-pressure rubber joints, rubber shock absorber etc..
How do you remove the black dirt on the rubber?
You should be rubber silicone, most of all is blackTry rubbing it with diluted alcohol.
