1.Higher intrinsic viscosity and molecular weight 2.Improving external and internal quality of PVC

HELITM HPA-41 is a special PVC foaming regulator developed by our R&D Centerl,its

molecular weight and viscosity is higher comparing with other general processing aid,it has better flowability and it can effeciently improve surface-gloss of PVC products.

products advantages:

1.higher intrinsic viscosity and molecular weight

2.improving external and internal quality of PVC finished products

3.shortening fusion time,enhancing productivity

4. improved surface smoothness and glossness of PVC products

5.better fluidity

application field:

Owing to the higher viscosity and good flowability,HPA-41 can effectively improve the surface glossness of PVC products and it can also make the PVC foaming products have the even and small bubble, and so when HPA-41 is used to produce PVC foaming products,it can sucessfully reduce the production cost by decreasing density of PVC foaming products.HPA-41 is mainly recommended to produce thin PVC foaming sheet and board with higher surface gloss needs, if necessary,our R&D center will be happy to supply the relevant technical support according to the customers requests

Remarks:HPA-41 is equivalent to PA-40
