Product Name:Glass Bead Reinforced Natural PBT (Ultradur B4300K4)
English Name:Glass Bead Reinforced Natural PBT (Ultradur B4300K4)
CAS No.:26062-94-2
Aliases:PBT, Polybutylene terephthalate, Glass bead reinforced polybutylene terephthalate
Molecular Formula:(C12H12O4)n
Physical Properties:Melting point 220–230°C; crystallization rate faster than PET. Stable mechanical properties with tensile strength and tensile modulus similar to nylon; low friction coefficient with self-lubricating property; low water absorption; excellent electrical properties; good dimensional stability; resistant to chemicals and oils. Glass transition temperature (Tg) approx. 30°C; heat deflection temperature (HDT) under load 60°C; impact strength is relatively poor, typically used as glass-fiber reinforced FR-PBT. A high-crystallinity thermoplastic.
Uses:Used in electrical and electronic components such as non-fuse circuit breakers, electromagnetic switches, flyback transformers, appliance handles, connectors and housings; automotive parts such as door handles, bumpers, distributor caps, fenders, wire harness covers and wheel covers; industrial parts such as OA fans, keyboards, fishing reels and lamp covers. The glass bead reinforced grade provides low warpage and excellent dimensional accuracy, making it suitable for precision component manufacturing.
Technical Specifications:
Melting point 220–230°C; crystallization rate faster than PET.
Glass transition temperature (Tg) approx. 30°C; heat deflection temperature (HDT) under load 60°C.
Extremely low water absorption; maintains excellent electrical properties during long-term use over a wide range of temperature and humidity.
Low friction coefficient with self-lubricating property; low wear loss, suitable for applications requiring friction and wear resistance.
UL certified: flame-retardant grade 94HB, self-extinguishing grades 94V-0 and 94V-2.
