Tinuvin® 1577 ED

Technical Datasheet | Supplied by BASF
Tinuvin® 1577 ED by BASF is a hydroxyphenyl triazine grade. Acts as a UV absorber. Exhibits very low volatility and good compatibility with a variety of polymers, co-additives and resin compositions. Allows polycarbonates and polyesters to achieve a higher resistance to weathering than conventional benzotriazole UV absorbers. Suitable for polyalkene terephthalates & naphthalates, linear and branched polycarbonates, modified polyphenylene ether compounds, and various high performance plastics. Compatible with blends & alloys, such as PC/ ABS, PC/PBT, PPE/IPS, PPE/PA and copolymers as well as in reinforced, filled and/or flame retarded compounds, which can be transparent, translucent and/or pigmented. Tinuvin® 1577 ED (0.2-6% by weight) can be readily incorporated into the polymer by using conventional techniques such as powder, solution, or melt blending.
