Natural Rubber

 

Natural rubber is a versatile and important raw material that is derived from the latex sap of the rubber tree, scientifically known as Hevea brasiliensis. This tree is native to the Amazon rainforest but is also cultivated in various tropical regions around the world, particularly in Southeast Asia.

Natural rubber continues to be a crucial material in various industries, and its properties make it irreplaceable in many applications despite the availability of synthetic alternatives. Sustainable and responsible sourcing practices are increasingly important in the rubber industry to address environmental and social concerns.

Skim Block Rubber

Carbon Black
Hard Grades
 
  1. Gives high wear-resistance, high resistance to rupture, tear resistance to rubber, high dynamic hardness and elastic rebound to rubber, high durability, and low hysteresis.
  2. Widely used for producing: high quality, protecting rubbers and protecting stocks, transporter and conveyor belts, breaker rubber, technical seals, cable covers. It is also used for producing high quality rubber molded articles working in hard conditions.
