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.
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
