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, injection and blow 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.
