Document Type and Number:
WIPO Patent Application WO/2021/140558
Kind Code:
A1
Abstract:
[Problem] The invention addresses the problem of providing a polybutylene terephthalate resin pellet having improved meterability, so that, when conducting injection molding to obtain a formed product from a polybutylene terephthalate resin, the "measurement time", during which one shot worth of molten resin is measured in a cylinder, can be shortened. [Solution] The problem is solved by setting, in a polybutylene terephthalate resin pellet containing a lubricant, a specific range for the amount of lubricant leaching to the pellet surface.
