摘要:
To provide a practical infrared transmissive protective cover capable of detecting a heating abnormality of an internal heating element and the like by visual observation and by using infrared rays. The infrared transmissive protective cover includes a light transmission section, the light transmission section is made of a resin sheet containing a resin composition, and a total light transmittance of the light transmission section in a visible light region is 70% or more, and an average infrared transmittance in a wavelength range of 8 to 14 μm is 5% or more.

A microporous membrane made of polyolefins which comprises polyethylene (PEA) 8-60 wt. % of which is accounted for by components having a molecular weight of 10,000 or lower and in which the ratio of the weight-average molecular weight (Mw) to the number-average molecular weight (Mn), Mw/Mn, is 11-100 and the viscosity-average molecular weight (Mv) is 100,000-1,000,000 and polypropylene, and which has a content of components having a molecular weight of 10,000 or lower of 8-60 wt. %, a porosity of 20-95%, and a degree of thermal shrinkage at 100° C. of 10% or lower.
摘要:
To provide a stretch-formed sheet of ultra-high molecular weight polyolefin having excellent transparency and mechanical properties, while being relatively thick. A stretch-formed sheet of ultra-high molecular weight polyolefin having a thickness of 0.2 mm or greater and having an internal haze of 70% or less in the direction of the thickness, is prepared by stretching at least in one direction a formed article of ultra-high molecular weight olefin having a density of 925 kg/m3 or less and containing a polymer of ultra-high molecular weight polyolefin having an intrinsic viscosity of 7 dl/g or greater as measured in a 135° C. decalin solution, at a temperature of less than the melting point (Tm) of the ultra-high molecular weight polyolefin and at ordinary temperature or higher.
