Polyester Veil for FRP Pipe Winding
Mar 01, 2019|
View:346The use of polyester veil in the FRP process can significantly improve the appearance of the product, improve impact and wear resistance, improve corrosion resistance and weather resistance, and make FRP products suitable for more demanding environments.
For pipe winding, usually small width polyester veil such as 250mm is used, with high tensile strength to avoid rupture during winding. Specification as below:
