Polymer coated glass fiber mat

摘要

A facer sheet (20) adapted to receive a prefoam mixture during a structural laminate forming process comprises a first predominantly glass fiber mat (22) having first and second outer surface (22a,22b) and a polymeric material (24) applied to the first outer surface of the mat. The polymeric material acts as a substantially impervious barrier to the liquid prefoam mixture received at the second outer surface of the mat during forming process of a structural laminate (10).
