Ranger PBT PBT-201-G20 202
Polybutylene Terephthalate
Beijing Ranger Chemical Co., Ltd.
产品说明：
Unreinforced grades have abundant strength andflexibility, and have strong characteristics againstbrittleness.
UL-certified slow-burning(94HB) and self-extinguishinggrades(94V-0,V-2) exist, and electrical properties exhibited arethe highest of any thermoplastic.
Low water absorption is exhibited, and excellent electricalproperties(CTI and GWIT) are retained over extended periods ofusages, even with widely varied temperature and humidityconditions.
The surface of molded products is smooth, and a low coefficient offriction is exhibited.As the amount of froction is low, PBT issuitable for use in application re friction and wearproperties.
The material is exceptionally reliable, with small in-usedimensional variation, and superior molding stability anddimensional precision.
Long-term chemical resistance is exceptional, and at roomtemperature, there is almost no degradation in propertiesafter.
Both unreinforced and reinforced grades exhibit exceptionalflowability, and excellent processability.
Application:VCD drive frames\ Connectors\ Trimmers\ Switch buttonsfor gas-fired instantaneous water heaters\ Relay blocks\ Driers\Rectifiers\ Outer handles\ Height sensor cases\ Door mirror stays\Drive component housings\ Energy saving lamp.
