NOVELTY - Electrostatic modified film comprises 40-60 pts. wt. antistatic particles and 40-60 pts. wt. thermoplastic polyurethane thin particles. USE - The electrostatic modified film is useful in automobile process, shoe material, garment, chemical industry, electronic and medical fields. ADVANTAGE - The electrostatic modified film has excellent antistatic property, softness, low-temperature resistance, and anti-aging performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing electrostatic modified film, comprising (i) selecting specific amount of electrostatic particles and thermoplastic polyurethane thin particles and mixing; (ii) adding the mixed material into the hopper of the extruder, where the temperature of the extruder in 1 section is 180-200℃, 2nd section is 200-220℃ and 3rd section is 220-230℃, plasticizing and turning on machine, the speed of the extruder is 40-60RP; (iii) adding the materials respectively into the film blowing machine blowing film and controlling the thickness uniformity of the blown film to be controlled at ±3%; (iv) stretching and shaping the film produced by a stretch and shaping machine, and the thickness after stretching is controlled within 3%; and (v) placing the film for stretching and shaping for 30-50 minutes, rolling up the tube film and storing in the warehouse after testing.
