Abstract: PROBLEM TO BE SOLVED: To provide a polyester resin composition for enabling formation of a molding which has earthenware-like massive feeling, texture and gloss, and further, is excellent in chemical resistance, and impact resistance by compounding a polybutylene terephthalate resin, a specific polyester copolymer, and a glass bead. SOLUTION: A polyester resin composition comprises a polybutylene terephthalate resin of 10-50 wt.%, 10-50 wt.% of a polyester copolymer comprising at least two of either one or both of a diol component and a dicarboxylic acid component, and a glass bead of 10-70 wt.%. The polyester copolymer is preferable in that the diol component is selected from an ethylene glycol residual group and a cyclohexane dimenthanol residual group, and that the dicarboxylic acid component is selected from a terephthalic acid residual group and an isophthalic acid residual group. Further, in the case of selecting two of the ethylene glycol residual group and the cyclohexane dimenthanol residual group as the diol component, a molar ratio of the former to the latter is preferably 50-5 mole %/50-95 mole %.

Abstract: PROBLEM TO BE SOLVED: To provide a floor support made of a synthetic resin, having excellent mechanical strength and chemical resistance and capable of guaranteeing a smooth floor lifting operability by molding at least one of multiple tubular members which are relatively moved and expanded or shrunk in the axial direction with a polyamide resin composition containing a reinforcing material of a specific wt.%. SOLUTION: Press nuts 2, 2 are screwed to both end sections of a bolt 1, and stopper nuts 3 for stopping the loosening of the press nuts 2 are screwed inside to form this floor support. A polyamide resin composition mixed with a reinforcing material of 1-60 wt.% unto a polyamide resin is injection-molded into a completely round cylindrical shape to form the bolt 1, thus compressive strength is improved and can be kept at a high level under the high-humidity condition. Male screws 4a, 4b having opposite screw directions are provided at both end sections across the center section in the axial direction of the bolt 1. The polyamide resin composition mixed with the reinforcing material into the polyamide resin is likewise injection-molded into the completely round cylindrical shape to form the press nuts 2 and the stopper nuts 3.

Abstract: PROBLEM TO BE SOLVED: To provide a high bending characteristic, color tone and lightweight quality by containing a polyester resin having a specific range of weight parts composed of cyclohexane dimethanol and an aromatic dicarboxylic acid, and one or more types of rod type inorganic substances within the specific range of weight parts. SOLUTION: A polyester resin composition is prepared through the process where 60 to 10 pts.wt. of glass fiber as one or more of rod type or acicular inorganic substances are blended, melted and kneaded with 40 to 90 pts.wt. of resin as a copolymer made of cyclohexane dimethanol and aromatic dicarboxylic acid consisting of 95mol% of telephthalic acid and 5mol% of isophthalic acid. This polyester resin composition is used and extrusion molded at the resin temperature of 300 deg.C and the die temperature of 150 deg.C, thereby preparing resin chopsticks. As a result, the chopsticks have a high bending characteristic, color tone and lightweight quality.
