An apparatus for injection molding synthetic resin materials comprises means for injecting the material to be molded, mold means having a cavity for receiving the material from said injecting means, entrance passage means connecting said injecting means with the cavity of said mold means and valve m ...
Rare-earth metal salts of organic carboxylic acids of this invention constitute themselves phosphors which exhibit unusually high luminescence efficiency, excel in chemical and physical stability and weatherability, show high affinity for other chemical substances and promise extensive usefulness in ...
Foamable synthetic resin materials are plastified and injected into a mold cavity in an amount less than the volume of mold cavity and a body of gas under pressure is charged in the mold cavity in such manner that it is enclosed by said resin materials. When the injected resin materials sets at leas ...
A multi-layered article molded according to the present invention has in its cross-section a triple-layered structure consisting of two surface layers and a core layer interposed between said surface layers, said triple-layered structure being injection molded in a single shot from two kinds of ther ...
A thermoplastic synthetic resin such as polyethylene or ethylene-vinyl acetate copolymer resin containing 0.1 to 10 wt. % of a specific additive selected from specific classes of compounds, namely saturated higher fatty acid amides, saturated higher aliphatic amines and complete esters of saturated ...
A process for producing moldings comprises the steps of injecting a plastified synthetic resin into a mold cavity, thereafter or simultaneously injecting heated fluid having a viscosity of 0.01 - 100 poise into the same mold cavity to fill it with said fluid in such a manner that said heated fluid i ...
A composition for shrinkable film which excels in heat-sealability, transparency, strength, and particularly low-temperature quick shrinking property and, therefore, suits production chiefly of packaging materials, a film made of the composition and a process for the manufacture of the film are disc ...
An aqueous dispersion of partially neutralized ethylene/.alpha.,.beta.-ethylenically unsaturated carboxylic acid copolymer having a specific composition distribution of the acidic units is found to have an excellent film-forming property and suitable for coating of various substrates. Articles coate ...
A high-orientation multilayered film incorporates at least one cold drawn, highly oriented resin layer excellent in mechanical strength and suitable mainly for use as packaging material. Because of its specific stratal construction which is highly adaptable to afford a wide variety of specific funct ...
