摘要:
A polyamide resin pellet for a miniature part, comprising a polyamide resin (A) whose melting point as measured by DSC is in the range of 280 to below 330° C., which has an average volume of 0.001 to 21 mm3, the average volume determined by randomly sampling 50 pellets, measuring the weight and specific gravity of each of the pellets and dividing the weight by the specific gravity. The polyamide resin pellet exhibits low water absorption and is excellent in moldability, mechanical strength characteristics and heat resistance. Further, it has specified average volume, configuration, average diameter and average length, so that, in an injection molding, plasticization is smoothly effected to thereby enable obtaining a molded item or article which exhibits low dispersion of weight and strength and has excellent hue. The polyamide resin pellet is especially suitable for use in a molding material for forming miniature parts for motor vehicles and electrical or electronic equipments.
