    摘要: A porous membrane that includes a first zone, the first zone including a crystallizable polymer; and a first nucleating agent, the first nucleating agent having a first concentration in the first zone, the first zone having a first average pore size; and a second zone, the second zone including a crystallizable polymer; and a second nucleating agent, the second nucleating agent having a second concentration in the second zone, the second zone having a second average pore size, wherein the crystallizable polymer is the same in the first zone and second zone, wherein the first average pore size is not the same as the second average pore size, wherein the first nucleating agent and the second nucleating agent are the same or different, wherein the first concentration and the second concentration agent are the same or different and with the proviso that the first nucleating agent and the first concentration are not the same as the second nucleating agent and the second concentration. Methods of making membranes are also disclosed.

    摘要: A protective cover including a bellows portion wherein a plurality of valleys and peaks are arranged alternately. The valleys include a plurality of large valleys and a plurality of intermediate valleys whose inside and outside diameter dimensions at bottoms are greater than those of the large valleys, and the large valleys and the intermediate valleys are arranged alternately. Small valleys whose inside and outside diameter dimensions at bottoms are greater than those of the intermediate valleys are respectively arranged between the large valleys and the intermediate valleys. The peaks are respectively arranged between the large valleys and the small valleys as well as between the intermediate valleys and the small valleys, and apexes of the peaks have a same outside diameter dimension as one another. The apexes of the peaks are made thinner than the bottoms of the large valleys.

    摘要: VDF-co-(TFE or TrFE) polymers having a molecular weight of at least about 1,000,000 g/mol and a melt temperature less than about 240° C. The VDF copolymer contains at least about 50 mol % VDF monomer and may include an amount of at least one other monomer. The VDF copolymer may be used to form a membrane that has a node and fibril structure. The membrane has a percent porosity of at least 25%. A VDF-co-(TFE or TrFE) polymer membrane may be formed by lubricating the VDF copolymer, subjecting the lubricated polymer to pressure at a temperature below the melting point of the VDF copolymer to form a preform material, and expanding the preform material at a temperature below the melting temperature of the VDF copolymer. Dense VDF copolymer articles, filled VDF copolymer membranes, and VDF copolymer fibers are also provided.
