Product Details

M4-AB Combo Mats are a commonly used form of composite reinforcement composed of Boron-free woven roving and Boron-free chopped roving stitch-bonded into one fabric. The input Boron-free rovings provide higher mechanical properties (modulus of elasticity) than E glass, superior chemical corrosion resistance, especially very similar acid resistance with traditional ECR glass. Without any content of B2O3 and F2, Boron-free glass is environmental-friendly throughout all its production process.
