Properties：the glass transition temperature of natural rubber raw rubber is -72°C, the rubber flow temperature is 130°C, the initial decomposition temperature is 200°C, and the intense decomposition temperature is 270°C.

Natural rubber is a non-polar substance that dissolves in non-polar solvents and non-polar oils. Natural rubber is not resistant to cyclohexane, gasoline, benzene and other media. Unvulcanized rubber can dissolve in the above media, while vulcanized rubber swells. Natural rubber is insoluble in polar acetone and ethanol, and even more insoluble in water. It is resistant to 10% hydrofluoric acid, 20% hydrochloric acid, 30% sulfuric acid, and 50% sodium hydroxide.

Main uses of natural rubber:

Natural rubber is widely used in the fields of industry, agriculture, national defense, transportation, transportation, machinery manufacturing, medicine and health because of its strong elasticity and good insulation, plasticity, water and gas insulation, tensile strength and wear resistance. and daily life, such as tires used in transportation;

Industrial conveyor belts, transmission belts, various sealing rings; medical gloves, blood vessels; rubber shoes, raincoats, warm water bags, etc. used in daily life are all made of rubber as the main raw material. Cannons, tanks, and even rockets, satellites, spacecraft, and space shuttles in cutting-edge technology require a lot of rubber parts.
