Properties: It is white to off white granular. It is insoluble in water and toluene etc..
Performance Benefits: It is a new-style hindered amine light stabilizer(HALS).Its performance is better than light stabilizer 770,944 and 783.Such as:
1.Excellent surface stabilization(glossness,chaling,discoloration).
2.Minimal color contribution,low volatility.
3.High solubility/compatibility in polyolefins/styrenics,non blooming.
4. Performance synergy with other stabilizers,especially high MW HALS and UV absorbers.
Uses: It is mainly used in tape,injectionandblow molding,film and metallocene of PE,tape,film,fiber and injection molding of PP,TPO,POM,PA,ASA,ABS,HIPS,SAN,PUR and rubber.The addition is 0.2~1.2%wt.The suggested addition is 0.6%wt.
Storage: Store in a tightly closed container.
Package: 20kgs/box or as required by the customer.
Expiration Date: 2 years
