UV absorber UV-234

• High molecular weight hydroxyphenyl benzotriazole UV absorbers have excellent photostability to polymers
• The ability to absorb ultraviolet light at 300-400nm is strong, while the absorption in the visible spectrum is small, especially for homopolymers and copolymers. Good thermal stability, low volatility, strong light absorption, good compatibility with polymers.
• FDA approved for use in food contact materials
• It has good compatibility with a wide range of polymers and synergies with hindered amine light stabilizers and most antioxidants.
• Good heat stability.

UV-SORB UV-234 is a hydroxybenzotriazole UV absorber that converts UV rays into heat by photochemical action.

It has good thermal stability and has a good effect on polymers that need to be processed at high temperatures. Such as polycarbonate, polyester, polyacetal, polyamide, polyphenylene sulfide, aromatic copolymer, thermoplastic polyimide, polyvinyl chloride, styrene and so on.

It has good compatibility with most polymers and low volatility, making it suitable for films and fibers. It is also suitable for high temperature resistant powder coatings, roll materials, etc. Protect the material from ultraviolet radiation.In outdoor products, it can be used together with phenolic antioxidants and phosphite ester antioxidants.

The package is 20kg or 500kg/ bag, which can be customized. No special safety equipment is required, according to the general chemicals cool, dry, ventilated storage, away from fire, heat sources, strong oxidants, strong reducing agents. It is recommended to take proper protective measures, try to avoid long-term contact with the product, and rinse with plenty of running water after contact with eyes or skin. Keep for 12 months under suitable storage conditions. Additional safety and operational information can be found in theTP-SORB UV-234 SDS.
