YK-168 features good solubility in resin, low volatility, high thermal stability, high resistance to extraction, and it is nonstained and nondiscoloring. YK-168 can prevent polymer from heat degradation in processing and make polymer maintain its intrinsic mechanical property and ageing resistance. YK-168 is widely used in PE, PP, polyoxymethylene, ABS, PS, PVC, engineering plastic, rubber and other petroleum products. YP-168 can be used within polymerization, producing and end-use.
