Light stabilizer can effectively improve the thin products, especially fiber and film products.In the thick section products, it is especially suitable for polyethylene products.In addition, it can also be used in place requirements can be in contact with food.It is high efficient heat stabilizer of thick and thin products, with good resistance to extraction.
|
Including polyethylene thin plastic (such as PP, PE) olefin hydrocarbon such as EVA, PP copolymer with elastomer blend.In addition, also used for polyformaldehyde (POM), polyamide (PA), polyurethane (PU), hard and soft PVC and PVC blend, as well as the styrene elastomer and adhesive body also has a good effect
