Sunny Chemical Corp.Ltd.

Polymer additives are added with small amounts to protect polymers performance by preventing loss of mechanical strength, cracking, crazing, yellowing, and loss of gloss due to day-to-day exposure to air and light.
Sunny Chemical Co.,Ltd. specialise in manufacturing of ultraviolet light absorber-uv326,uv327,uv328,uv329,uvp,uv9,uv531,uv320,uv234,uv5411,uv360,Uv571,uv292,uv622,uv770,uv944,AO1010,AO1076,AO1790,AO245,AO168,AO215,AO225,AO900,AO2215,AO2777
Our polymer additives, including UV absorbers, Antioxidants, Photoinitiators, Optical Brightener Agents (O.B.A.) and Colorants.
The recommended polymer additives hold the following advantages:
1) Excellent chemical stability
2) Excellent heat stability
3) Good compatibility with polymer
4) Low volatility
5) Low toxicity and small pollution
