The fabric is designed for the occasion which requires high flame retardancy. We adopt special flame retardant dipping system. As the flame retardant rubber formulas such as adhesive tape for domestic conveyor belt are different, we can adjust flame retardant dipping formula and develop the flame retardant dipping system specifically according to user’s requirements.
High tensile strength
Less stretch
High adhesion
Excellent troughability
High impact resistance
