Why is it recommended to use powder chopped strand mat for making FRP molds?
June 30,2022
    As a basic product in the glass fiber reinforced plastic industry, chopped strand mat (also called CSM) is widely used in the molding of glass fiber reinforced plastic molds and parts. In general, fiberglass mat for polyester resin systems are available from almost any composite supplier with minimal price and quality variation.

For many mold manufacturers, it is generally believed that the weight of glass fiber mat determines the resin infiltration speed, such as 300g or 450g, but this is not entirely the case.
