Use: photostabilizer uv944 is a high-molecular stabilization agent for obstructive meds. Because of the high molecular mass and the multiplicity of official groups in the molecules, they are characterized by high light stability, good heat tolerance, good extraction resistance, low volatility, low mobility and good resin compatibility. Especially for abs, eva film, polystyrene, polypropylene fibres, polypropylene tape, low-density polyethylene film and food packaging
