Rubber products are very common in life, just like the soles of shoes we usually wear, and car door and window sealing strips, etc., but do you know what kind of rubber materials these rubber products are made of? Hexin Rubber can share this knowledge with you!
First get to know natural rubber (NR)

       Natural rubber (NR) is a natural polymer compound with cis-1,4-polyisoprene as the main component. 91% to 94% of its components are rubber hydrocarbons (cis-1,4-polyisoprene). Diene), and the rest are non-rubber substances such as protein, fatty acid, ash and sugar. Natural rubber is the most widely used general-purpose rubber. Normally what we call natural rubber refers to the elastic solids made from natural rubber latex collected from Brazil rubber trees through coagulation and drying processes. Natural rubber is a natural polymer compound with cis-1,4-polyisoprene as the main component. Its rubber hydrocarbon (cis-1,4-polyisoprene) content is more than 90%, and it also contains A small amount of protein, fatty acid, sugar and ash, etc. To

       Natural rubber NR (Natural Rubber) is made from rubber tree latex, which is a polymer of isoprene. It has good abrasion resistance, high elasticity, tear strength and elongation. It is easy to age in the air, When heated, it is easy to swell and dissolve in mineral oil or gasoline. It is resistant to alkali but not strong acid. Advantages: Good flexibility, acid and alkali resistance. Disadvantages: Not weather-resistant, oil-resistant (vegetable oil resistant). It is a raw material for making tapes, hoses, and rubber shoes. It is also suitable for making shock-absorbing parts, and products used in liquids with hydroxyl radicals such as automobile brake fluids and ethyl enzymes.
