PBT树脂4130线圈骨架注塑材料阻燃级 (CAS No.None)

Product Name:PBT Resin 4130 Flame Retardant Grade for Coil Former Injection Molding

English Name:PBT Resin 4130 Flame Retardant Grade for Coil Former Injection Molding

CAS No.:26062-94-2

Aliases:Polybutylene terephthalate 4130, Flame Retardant PBT 4130, PBT for coil former

Molecular Formula:(C12H12O4)n

Physical Properties:PBT resin 4130 is an off-white granular thermoplastic polyester with a density of approximately 1.31 g/cm³ and a melting point of 220–230°C. It exhibits excellent mechanical strength, electrical insulation, chemical resistance, and dimensional stability. The resin features rapid crystallization and a short molding cycle. It achieves a UL94 V-0 flame retardant rating and a high heat deflection temperature, making it suitable for thin-walled precision parts.

Uses:Primarily used for manufacturing precision injection-molded electronic and electrical components such as coil formers, relays, connectors, and transformer bobbins. Its superior flame retardancy makes it ideal for electrical insulating structural parts with high safety requirements.

Technical Specifications:

Injection molding temperature: 250–270°C

Mold temperature: 50–75°C

Drying conditions: dry at 110–120°C for approximately 3 hours

Injection characteristics: solidifies and crystallizes rapidly upon cooling from the molten state, resulting in a short cooling time; if the nozzle temperature is improperly controlled (too low), the runner may cool and solidify, causing nozzle blockage

Flame retardant rating: UL94 V-0
