Natural rubber, in its milky sap, is tapped from the HeveaBrasiliensis tree. Most of the latex is either processed into sheets or solid crumb rubber. It can also be kept in its liquid form through use of chemicals to prevent the latex from coagulation.
Latex is a sticky, milky colloid drawn off by making incisions in the bark of the Pará rubber tree (Heveabrasiliensis) and collecting the fluid in vessels in a process called “tapping”. The latex then is refined into rubber ready for commercial processing.
SSBR is one of the most manufactured synthetic rubber in the world. For use in high-performance tires, S-SBR products provide an excellent balance between wet grip, low rolling resistance, and abrasion resistance in silica .
