Natural rubber products.
Natural rubber and natural rubber specialty products are supplied by the company for use in the rubber industry. Products include SMR (Standard Malaysian Rubber), which includes standard and CV controlled natural rubber products that are graded by technical specifications, not by the conventional visual standards. These SMR rubbers are said to represent very high quality, clean latex grades of natural rubber. DP-Poly de-proteinized, highly purified natural rubber products have higher hydrocarbon content and lower dirt, ash, nitrogen and volatile matter compared to traditional natural rubber. DP-Poly is available in a controlled viscosity (CV) grade and a standard (S) grade without controlled viscosity. PA-80 and PA-57 natural rubber products are pre-crosslinked products which act as a processing aid when blended with natural rubber, SBR, polychloroprene and nitrile rubber. PA-57 is a 40% non-staining, oil-extended version of PA-80. PA products are said to provide superior processing qualities in extrusion, calendering and open steam curing operations. Megatex MG-30 and MG-49 am modified, high-performance, specialty natural rubber products prepared by graft polymerization of poly methyl methacrylate (PMMA) into a natural rubber latex. Superpoly (SP) includes specialty polyisoprene natural rubber products that am partially pre-crosslinked, high performance elastomers available in bale form.
