Acrylic processing aid P-125

Description

P-125 is used to promote fusion of PVC compound. It can be widely used for rigid PVC products such as PVC profile, PVC pipes, PVC pipe fitting and PVC foaming products etc.

Key property

• Promote fusion of PVC compound
• Improve surface gloss of PVC finished products
