Product features and applications
1. UV-P is an ultraviolet absorber for 290-400nm, with good light stabilization effect - it converts ultraviolet rays into heat energy through photochemical action.
2. UV-P can provide UV protection for most polymers, and is used in polyvinyl chloride, polystyrene, polyester and acrylic resins, vinyl and vinyl/acrylic polymers, polyurethane, polycarbonate and fiber acid ester.
3. UV-P has good thermal stability and can be used for high-temperature processing of plastics such as polycarbonate under normal processing conditions.
