It has the characteristics of high temperature resistance, pure colour light, strong fluorescence and good whitening effect, and is suitable for the whitening and brightening of polyester, nylon fiber, polypropylene fiber, PVC, ABS, EVA, PP, PS, PC and high temperature molding plastics.



    1. 1.Brilliant, neutral white cast that compensates for yellowing 
      2.Low volatility and excellent heat resistant make the product ideal for use in fibers and in engineering plastics processed at high temperatures 
      3. In combination with dyes, produces particularly bright shades 
      4. Good light fastness

Suitable for all kinds of high temperature molding plastics, including polycarbonates, polyesters, and polyamides(nylon).


In 25kg drums (cardboard drums), lined with plastic bags or according to customer's requirements.
