Pultrusion Peel Ply is the most important consumables in the manufacturing of pultruded composite materials. After the reinforced fibers are impregnated with resin, the Peel Ply is laid on its upper and lower surfaces, and together they enter the mold and solidify into shape. The main function of it in the pultrusion system is to prevent the product from sticking to the mold, improve the surface quality of the product, give the product surface texture and a certain roughness for subsequent secondary molding for products.
