An open cell body is made of hard vinyl chloride resin made by extruding a compound composition consisting essentially of a vinyl chloride resin made by a suspension polymerization method or a block polymerization method, an ultramacromolecular weight acrylic processing aid, joint use of an organic stabilizer containing a metal of the group I in the periodic table and an organic stabilizer containing a metal of the group II in the periodic table, or an organic composite stabilizer containing the both metals, joint use of an anionic surface active agent and a nonionic surface active agent, or joint use of an anionic surface active agent and a low polymerization degree polyolefin or waxes, a thermal decomposing organic blowing agent such as azodicarbonamide, and, as occasion demands, a powderly filler such as calcium carbonate.

Open cell body made of hard vinyl chloride resin

A hard polyvinyl chloride resin composition is provided, which contains as essential components thereof the following components (a)-(e):

Hard polyvinyl chloride resin composition and open-cell foam made of

An apparatus for installing an escape slow lowerer stably at an arbitrary place on a building. The apparatus has a ladder body, horizontal rods mounted on the ladder body and vertical rods mounted slidably and lockably on the horizontal rods to form a gate-like shape for holding the building. The apparatus further comprises a foldable ladder connected to the ladder body and a column having a metal fixture for supporting the escape lowerer.
