Description

Natural rubber is the name applied to the polymer cis-1,4-polyisoprene obtained chiefly from the 4590 RUBBER, NATURAL latex of the Hevea brasiliensis tree. There are two main solvents for rubber: turpentine andnaptha (petroleum). Because rubber does not dissolve easily,the material is finely divided by shredding prior to immersion.Natural rubber has been partially replaced by synthetics,particularly styrene–butadiene, as a generalpurposerubber. High resilience, low heat buildup, andeasy p

Natural Rubber Use and Manufacturing

Natural rubber can be used to make tires, rubber tubes, rubber shoes, gloves, aircraft and auto parts. Natural rubber is one of the main materials for making tires. About 70% of natural rubber is used in tire manufacturing. Natural rubber has good elasticity and wear resistance, making it an ideal choice for tires for vehicles such as cars, trucks, motorcycles, bicycles and airplanes. Natural rubber is also used in the production of various rubber tubes and rubber seals. For example, natural rubber hoses can be used for water pipes, gas pipes, oil pipes, gasoline pipes, etc., and rubber seals are used in various fields of seals, valves, pipes and pumps. Natural rubber is also one of the main raw materials for the production of rubber shoes and gloves. Rubber shoes and gloves are important supplies to protect the human body from physical and chemical damage. They are waterproof, non-slip, acid and alkali resistant and wear resistant, making them ideal for industrial, agricultural, medical and home use. Natural rubber can also be used to make various aircraft and automobile parts. For example, rubber springs, rubber stops and rubber shock absorbers made of natural rubber are all used in the automotive field. In addition to the above applications, natural rubber can also be used to make a variety of rubber products, such as rubber pipe joints, rubber gaskets, rubber conveyor belts, rubber rollers, rubber MATS, rubber floors, etc. Natural rubber is a high performance, multi-functional material with good elasticity and wear resistance. Therefore, it is widely used in various fields and is known as ""green material"".
