FIELD: production of polymer materials. SUBSTANCE: invention relates to microporous polymer materials used in standard motor-car accumulators. Proposed composition and preparation method make it possible to prepare material with decreased consumption of plasticizer, with increased volume porosity and reduced electric resistance based on superhigh-molecular polyethylene, Aerosil (silica powder), plasticizer, and process additives. As sheet-shaping device before calender, gear pump with elongated gears is used. EFFECT: reduced cost and modified characteristics of product. |
