Rubber Natural

NATURAL RUBBER is a polymer of plant origin, the vulcanization of which produces rubber. Milky, white latex, containing rubber globules, is obtained by making an incision into the bark of rubber trees, the cultivation of which requires specific climatic conditions and rainfall.

Rubber tree plantations are mainly located in Southeast Asia (including Thailand, the world’s largest producer and Indonesia), Latin America and Africa.

In compound formulations, natural rubber reduces internal heat generation in tires, whilst offering high mechanical resistance. It is used in many parts of the tire, mainly used for truck and earthmover tire tread

Synthetic rubber

60% of rubber used in the tire industry is synthetic rubber, produced from petroleum-derived hydrocarbons, although natural rubber is still necessary for the remaining 40%.

Synthetic elastomers deform under stress and return to their original shape when the stress is removed (hysteresis).This property is extremely valuable for the manufacture of high-grip tires.

Synthetic rubber also provides other specific properties, most notably in the areas of longevity and rolling resistance. It’s mainly used for passenger car and motorcycle tire as it gives them good grip performances.

Metal and Alloys

Copper is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. Its density is 8.96 g/cm³. A freshly exposed surface of pure copper has a pinkish-orange color. People usually use copper material to make a conductor of heat and electricity. complex brasses with excellent cutting performance and wear resistance. Lead brass contains less than 3% lead.

Brass is an alloy of copper and zinc. If the alloy contains just copper and zinc, it is called ordinary brass. In order to improve the properties of ordinary brass, the raw material supplier usually adds 1%-5% tin, lead, aluminum, silicon, iron, manganese, nickel and other elements to obtain some updated brasses. They are called complex brass. Among them,  lead brass is one of the most important and widely used complex brasses with excellent cutting performance and wear resistance. Lead brass contains less than 3% lead.

In machining services, ordinary brass and lead brass are widely used to manufacture various precision parts.
