Chopped Strand Mat (Glass Fiber)
E-glass chopped strand mat for hand lay-up GRP lining and laminate construction.
Overview
Random fibre. Multi-directional strength.
Chopped Strand Mat is E-glass fibre chopped into 50 mm lengths and bound into a random non-woven mat by emulsion or powder binder. Hand lay-up grade dissolves readily in polyester and vinyl ester resin, allowing the mat to conform to complex shapes.
The primary reinforcement for hand lay-up GRP tank lining and pool construction. Used in combination with woven roving for higher-strength laminates.
Key Features
- E-glass fibre chopped to 50 mm length
- Random orientation – multi-directional strength
- Emulsion binder dissolves in resin
- Available in multiple areal weights
- Conforms to complex shapes
- Compatible with polyester and vinyl ester resin
