Product Introduction

Reinforced polyurethane resin pultrusion plate is a composite material plate produced by pultrusion process with high-strength glass fiber as the reinforcement and polyurethane resin as the matrix material. Compared with the plate of epoxy resin system, this product has the advantages of high production efficiency and excellent performance,and can be widely used in various large-scale wind turbine blades.
