    摘要: The purpose is to provide a porous polyolefin resin film which has high gas permeability and a high porosity, and which can exhibit excellent properties including break down properties when used as a separator for a non-aqueous electrolyte secondary battery. The present invention relates to a porous polyolefin resin film which is produced from a resin composition (a) containing a polyolefin resin as the main component and additionally containing organic-inorganic hybrid particles (f).

    摘要: The present invention provides a method for producing a PTFE fiber that makes it possible, unlike the emulsion spinning process, to obtain a polytetrafluoroethylene (PTFE) fiber, particularly a long PTFE fiber, without using a matrix material, is more productive than conventional production methods such as a slit yarn process, and is capable of enhancing mechanical properties and the degree of freedom in diameter of the obtained fiber. The method for producing the PTFE fiber of the present invention includes the step of reducing a diameter of a string-shape PTFE-containing solid material (a first solid material) by drawing the first solid material at a temperature equal to or higher than a melting point of PTFE. The first solid material can be obtained from a PTFE-containing solid material (a second solid material) containing water and a surfactant, by reducing an amount of the water contained in the second solid material.

    摘要: The flat tubular heat exchange body is provided with shoulders on each of its peripheral side walls at a fixed distance from each end. The ends of the bodies is shaped and sized to fit into a slot in a header pipe so that when the shoulders strike the surface of the header pipe, the invention is automatically fixed.
