Introduction: It 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 structutre 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‰
Cautions :
S or halogen may offer bad effects , or some stabilizer, insecticide and fire retardant may react with 944.
Please test before use.
