Product Description

Optical brightener for PVC is one of the most widely used plastics today. PVC (polyvinyl chloride) is hard and brittle without plasticizers. Optical brightener widely used in flexible PVC, man-made fibres and plastics. Various additives make it possible to vary the elasticity of the thermoplastic material. 

Not only the hardness of the plastic PVC can be easily changed, it also dyes well. Therefore, there is basically no PVC application in which optical brighteners cannot be used.We also find optical brighteners in almost all areas, where plastisols are used.
