[0002] Antistatic protective clothing is a special protective clothing with dust-free and antistatic properties suitable for electronics, optical instruments, pharmaceuticals, microbial engineering, precision instruments, oil fields, petrochemicals, electric power, coal and other industries. Or synthetic fiber fabrics blended with conductive fibers, but the current antistatic chemical protective clothing of fiber fabrics has poor moisture permeability, air permeability, and insufficient comfort, while TPU film has excellent waterproof, air permeability, flexibility and aging resistance. It is gradually applied in the field of antistatic protective clothing, but at present, the domestic TPU film products are mainly low-end and low-end. Low temperature, elongation, hydrolysis resistance, and heat resistance are not ideal
