摘要： The invention relates to a porous membrane having a particle filtration value of at least 10 under U.S. Military Standard MIL-STD-282 (1956), where the porous membrane is a polyethylene membrane made from a blend of UHMWPE and UMWPE. The membranes according to the invention are particularly useful for filters such as ASHRAE filters, HEPA filters and ULPA filters for example in heating, ventilating, respirators and air conditioning applications. The membranes are produced involving a biaxial streching step at low deformation speed.
