NR sponge
Natural rubber widely used in packing and cushioning material and general applications
NR is an abbreviation for natural rubber. Made from sap (latex) tapped from a rubber tree, natural rubber has a tensile strength and elasticity unobtainable from synthetic rubber, that is due to the presence of a material called polyisoprene. With superior wear resistance and cold resistance, natural rubber is also widely used in engineering packing and cushioning materials.
■ Main applications ： Carpet, footwear, cushioning, packing and engineering products
