Method for producing microporous sheet |
abstract |
Provided is a method of producing a microporous sheet material of a polymeric matrix of polyolefin, with finely divided and substantially water-insoluble filler distributed throughout the matrix, and a network of interconnecting pores communicating throughout the microporous material. The method includes: (a) forming a mixture of polyolefin, filler and a processing plasticizer composition; (b) extruding the mixture to form a continuous sheet; and (c) contacting the continuous sheet with a non-flammable extraction fluid composition to extract the processing plasticizer composition from the continuous sheet. The extraction fluid has a boiling point of 75°C or less, and is essentially free of trichloroethylene. The microporous sheet material has Tensile Strength equal to or greater than 800 kPa. A microporous sheet material also is provided. |
