Use of polyfluoroalkanes of the formula CX3-CY2-R (I> in which X radicals on the same C atom stand for hydrogen and/or fluorine, Y radicals on the same C atom stand for hydrogen, fluorine and/or CF3 and R stands for CH2F, CHF2, CH3, CF3, CF2-CH3, CF2CH2F, CH2-CH3, CH2-CH2-CH3 or -CH(CH3)-CH3 and a molecule of the formula (I) contains at least two fluorine atoms, as propellant gases. o

Polyurethane mouldings are stabilised by enrichment of the stabiliser at the surface by applying the stabiliser to the surface of the mould before introduction of the polymer and/or to the surface of the moulding after demoulding. Preferred stabilisers for this purpose are emulsions containing from about 0.5 to 1.5 parts by weight of the stabiliser, 3-7 parts by weight of a solvent, in particular ...

La présente invention concerne l'obtention de composant de polyol et des compositions à base de ce composant pour la fabrication de mousses plastiques de polyisocyanurate et de polyuréthane.

Le but de l'invention est de réaliser de telles mousses présentant une fragilité réduite, une grande résistance à la chaleur et une combustibilité diminuée.

Ce but est atteint à l'aide d'un comp...

A water-soluble coating composition adapted for imparting appropriate printing, especially off-set printing, and processing characteristics to a thermoplastic resin film to be used as a synthetic paper and a coated film prepared with the composition are provided. The coating composition comprises (A) 100 parts by weight of a water-soluble polymer containing tertiary or quaternary nitrogen, (B) 5 t...

PURPOSE:To seek to improve electric stability by interposing Ag powder sintered body between an Ag tube and a Bi-Ca-Sr-Cu-O oxide powder sintered body. CONSTITUTION:Bi-Ca-Sr-Cu-O oxide (Bi oxide) powder is molded into a compact 3, and the compact 3 is put in the center of an Ag tube 1, and also Ag powder is charged into between the compact 3 and the Ag tube 1, whereby an Ag compound tube is made, ...

PURPOSE:To enable it to be used while letting flow refrigerant into inside of a metallic sheath by burying an oxide superconductor inside the peripheral wall of a pipe-shaped metallic sheath. CONSTITUTION:A tape material 1 which is constituted by covering a tape-shaped consolidated substance 3 consisting of a superconductor or a precursor of the oxide superconductor with a metallic sheath 2 is for...

PURPOSE:To make it possible to manufacture an oxide high temperature superconductive line material out of sheath material having high possibility of practical use by boring a hole in a sheath material using a roller provided with a projection after applying wire drawing processing, and baking a superconductive line material in the oxygen atmosphere so as to make the oxygen diffuse. CONSTITUTION:Pr...

PURPOSE: To decide a reference axis of a pinion by fixing a pinion shaft having a mandrel having a centering member disposed inside by a nut or the like, conducting centering operation to a bearing race at a shaft end part, retracting a shoe, setting the bearing race eccentric, and then removing the mandrel. CONSTITUTION: Prior to center grinding of a pinion shaft 10, bearing races 20a, 20b are in...

PURPOSE:To prevent the strain, creases, shrinkage spots, etc., of a film at the time of shrinkage by specifying a shrinkage factor after specified heat treatment in one direction and the direction orthogonal to the direction and bringing maximum shrinkage stress at a special temperature in the same direction to a specific value or less. CONSTITUTION:Polyester is composed of polyester or copolymeri...

A primer composition is provided for forming a primer layer for a thermoplastic substrate for increasing the adhesion of protective hardcoats thereto. The composition dries rapidly under conditions of either high or low humidity to form a clear haze-free primer layer.

PURPOSE:To improve a wear resistance and prevent stripping of coating without generating static electricity by forming a wire clamp plate by the use of a silicon carbide sintered compact and coating its plate with TiN or TiC. CONSTITUTION:Clamp plates 1 and 2 where a wire is sandwiched directly between their pointed ends are shaped into the form of a silicon carbide sintered compact. Its compact i...
