UV RESISTANT AGENT ZH944
1.Introduction
ZH944 is one kind of high molecular Light stabilizer, with multiple functional groups. It can be used in low density PE film, PP tape, EVA film, ABS, PP fiber, PPE, polyacetals, polyamides, polyurethanes, PVC, PVC blending material, polystyrene, rubber and viscose. It can work with UV adsorbent because its special structure and large molecular weight( 3000). It also can be used in film and fiber. Also can be used as antioxidant and heat stabilizer of polymer. The dosage of agricultural film is 2‰.
