With its excellent combination of physical and mechanical properties, natural rubber plays a key role in transportation and industry. Tire manufacturing is its largest application, especially in the manufacture of truck, construction vehicle and aircraft tires that require low heat generation and high strength. In addition, it is also widely used in the manufacture of a variety of highly efficient shock absorbers, cushions, conveyor belts, hoses, rubber shoes, and medical gloves, rubber bands and other products that require a high degree of elasticity and strength.
