GW-540 ll is the improvel type of GW540. The chemical structure of GW-540 ll was remained unchanged as is with the parent GW-540, Hence GW-540 sustains the excellent anti-aging property. However in order to enhance the purity and decrease the impurity content through effective treatment GW-540, becomes much less smell and less irritant and toxicity than the parent GW-540. It is mainly used for anti-light, anti-heat and anti-oxygen aging of poly-alkene. It is used in great quantity in manufacture of agriculture membranes of polyethylene,ps. Poly-urethane, polyvinylchloride as well as in chemical fibers, rubber, coating-painting, electrical cable adhesives etc. |
