摘要:
An extrusion foamed article with a large cross-sectional area is made by extrusion foaming a mixture of an ionomer resin and a styrenic resin utilizing a volatile blowing agent. The process permits economic production of a novel thick, foamed article having well balanced properties.
摘要:
In order to achieve a container which is convenient for carrying, delivery, transportation and storage of a viscous liquid, which can be disposed by being crushed to a small volume size when it has become empty, and which prevents twisting or rising up of the lower half of the container during a mixing of a viscous liquid, a container A holding liquid is used, wherein a ring-shaped rim frame 2 is provided on the upper end of a flexible tubular main body 1, a bottom plate 3 is fitted onto an opening at the lower end thereof, and at least one ring-shaped trunk section frame 4 is provided on the outer circumferential surface of said tubular main body 1.
摘要:
The present invention is a system for filling a container main body at least whose drum body is made of a flexible film, with a viscous material. A viscous material is charged by the charging means into container main bodies conveyed by the container conveying means, the drum body of the container main body is pressed by the pressing means to cause the surface of the viscous material to bulge, and the opening of the reinforcing component of the container main body is capped by the capping means, allowing the opening to be capped in an air-tight manner with a lid member while virtually all of the air inside the container main body is evacuated, and preventing air from being left over in the container main body so as to prevent hardening, curing and deterioration in the quality of the viscous material that can be caused by such remaining air.
摘要:
An antistatic sheet material comprises a substrate layer, an electroconductive layer, and a surface layer. The electroconductive layer is disposed on the substrate layer and contains carbon black in such a manner that the carbon black partly protrudes into the surface layer. The surface layer is a thin transparent plastic layer. The sheet material possesses decreased surface resistance and exhibits excellent antistatic properties. The sheet material permits an object held thereunder to be clearly seen therethrough and enjoys high resistance to surface friction and never deteriorates any object which is in contact therewith. Thus, the sheet material of this invention is used advantageously as containers for objects which by their nature are vulnerable to electrostatic damage.
摘要:
Foamed thermoplastic mixture of ionomers and polyolefin polymers are produced by extruding the mix together with a volatile blowing agent at elevated temperature and pressure. The density of the foamed products is from of 15 to 45 Kg/m.sup.3 and they satisfy the requirements of extrusion foamability, compressive strength or rigidity, thermal resistance and adhesion properties.
