The wall portion has an outer face having a center-line average surface roughness Ra of less than 9.0 μm. The foamed cell has a cell diameter having a standard deviation of less than 40 μm in a thickness direction of the wall portion. | 03-03-2011 |
20100086755 | OXYGEN BARRIER MULTILAYER STRUCTURE, AND MULTILAYER PACKAGING MATERIAL AND MULTILAYER CONTAINER USING SAME - An oxygen barrier multilayer material for containers is developed that selectively shields oxygen from the outside and also shields volatile substances by-produced by oxidation reaction. Provided are a selective oxygen absorbent multilayer structure produced by co-extrusion having an oxygen absorbing layer containing an oxygen absorbing resin composition, an inner barrier layer (A) and an outer barrier layer (C) arranged inside and outside the oxygen absorbing layer, in which the oxygen transmission rate of the outer barrier layer (C) is smaller than the oxygen transmission rate of the inner barrier layer (A), and a multilayer packaging material and a multilayer container, using the selective oxygen absorbent multilayer structure. | 04-08-2010 |
20090029083 | RESIN PANEL AND METHOD OF PRODUCING THE SAME - Provided is a resin panel produced such that the positioning of a reinforcing material can be precisely done, rattling movement is prevented and distortion by molding shrinkage is not caused because the reinforcing materials are maintained in the foam. | 01-29-2009 |
20080261016 | Blow Molded Article With Surface Skin and Method for Production Thereof - Provided are a blow molded article with a surface skin, which allows the formation of a blow molded article having a desired expansion ratio and retains a required expansion ratio from the time of extruding and is free from the generation of a sink mark or a warp in a portion where the surface wall and the back wall thereof has been welded and allows the production of a blow molded article with a lightweight and highly rigid surface skin; and a method for producing the blow molded article. A panel ( | 10-23-2008 |
20080254261 | Interior Automotive Trim Part and Process for Producing the Same - An interior article for automobiles is provided having a light-weight and suitable rigidity without lowering moldability even if the amount of use of a thermoplastic resin is decreased. A panel having a hollow double-wall structure and constituting an interior part for automobiles is formed from a mixture of polyolefin resins comprised of a propylene homopolymer having a specific gravity of 0.93 or less (JIS K7112), exhibiting a melt flow rate of 0.3 to 3.0 g/10 minutes (JIS K7210) and exhibiting a bending modulus of 1400 MPa or more (JIS K6758), a crystalline propylene block copolymer having a specific gravity of 0.93 or less (JIS K7112), exhibiting a melt flow rate of 0.3 to 1.5 g/10 minutes (JIS K7210) and exhibiting a bending modulus of 1250 MPa or less (JIS K7171) and a high density polyethylene having a specific gravity of 0.925 to 0.965 (JIS K7112) and exhibiting a melt flow rate of 0.5 g/10 minutes or less (JIS K7210). | 10-16-2008 |
20080203749 | Shock Absorber For Vehicle - Provided is a shock absorber for a vehicle, which, when it is crushed, can break and open a part of the wall thereof earlier than the time of the break of an explosion inducing section, to thereby exclude the effect of the air being present inside a hollow portion and exhibit stable shock-absorbing capability and also maintain a satisfactory shock-absorbing capability over a wide range of temperature from a high temperature to a low temperature independently of the temperature of the open air.
