介绍 | High Potency Anti-UV for Thermoplastic Polyurethane Elastomer Introduction: GOYENCHEM GGK-680 prevents the processing light and weather induced degradation of polyurethane product. GOYENCHEM GGK-680 is a high potency type anti-uv and color stabilizer used in polyurethane .Especially suitable for polyurethane-foam?paint?leather?TPU GOYENCHEM GGK-680 can make your PU products meet the world standard of anti-yellow and UV light test. GOYENCHEM GGK-680 is used in polyurethane. Especially suitable for thermoplastic polyurethane. GOYENCHEM GGK-680 prevents degradation of thermoplastic polyurethane from processing, light and weather, especially for discoloration from sunlight. It does not affect initial color of TPU from synthesis process. Adding UV absorber into extruder from TPU synthesis process, the UVA have to drop into extruder between 2/3 to 4/5 of screw length. Advantages:
Application: GOYENCHEM GGK-680 is used in polyurethanes series such as Reaction lnjection Molding(RIM),Thermoplastic polyurethane(TPU)PUsynthetic leather,cast polyurethanes, PU Sealant , epoxy resin and adhesive System GOYENCHEM GGK-680 can be used in thermal-plastic polyurethane. In general, it is recommended 0.5 to 1 wt% based on polymer weight. |
