Natural Rubber is an elastomer harvested from the latex sap of rubber trees (Hevea brasiliensis). It is a highly elastic, resilient, and durable polymer used globally in numerous industries. Natural Rubber is prized for its excellent tensile strength, flexibility, abrasion resistance, and ability to withstand deformation. It is widely utilized in manufacturing tires, industrial goods, footwear, and medical devices. The product is available in various forms such as sheets, blocks, crepes, and latex concentrate.
