1. It is made of flame-retardant synthetic fiber with elasticity and breaking resistance after carding and increasing the fiber density layer by layer, adhering to high-performance polyester mesh and processing by hot air fusion.
2. Double-sided spray glue treatment and secondary flame retardant treatment, high strength with better elasticity, excellent flame retardant effect
3. With better anti-corrosion effect of all kind of solvent, acid-base and good resistance for high temperature.
