uv absorber manufacturers UV-P

uv absorber UV-P is a high-efficiency ultraviolet absorber, which can effectively absorb 270-340nm ultraviolet rays. It is mainly used for polyvinyl chloride, polypropylene, unsaturated resin, polycarbonate, polymethyl methacrylate, polyethylene, ABS resin, ring Oxygen resin, fiber resin, etc. This product hardly absorbs visible light, and is especially suitable for the manufacture of colorless, transparent and colored products. This product is allowed to be used for plastic products in contact with food.
