Product Name:SABIC PBT 310SEO
English Name:SABIC PBT 310SEO
CAS No.:26062-94-2
Aliases:Poly(butylene terephthalate), PBT resin, PBT engineering plastic
Molecular Formula:(C12H12O4)n
Physical Properties:Linear saturated polyester resin with a density of approximately 1.31 g/cm³, melting point around 225°C, and low water absorption. It exhibits high mechanical strength, good fatigue resistance, dimensional stability, and low creep; excellent heat aging resistance with a UL temperature index of 120-140°C after reinforcement; resistance to solvents without stress cracking; excellent electrical insulation properties with a dielectric constant of 3.0-3.2 and arc resistance of 120s; fast crystallization, good flowability, and low mold temperature requirements. However, it is susceptible to hydrolysis under high temperature and high humidity conditions and should be used with caution.
Uses:Mainly used in the manufacture of parts in electronic and electrical appliances, automotive, mechanical equipment, and other fields, such as connectors, relays, coil bobbins, automotive igniters, and gears. It is also suitable for precision structural parts and heat-resistant insulating components due to its excellent mechanical and electrical properties.
Technical Specifications:
Dielectric constant is 3.0-3.2, with arc resistance reaching 120s.
UL temperature index reaches 120-140°C after reinforcement, showing good heat aging resistance.
Fast crystallization, good flowability, and low mold temperature requirements provide excellent processability.
High mechanical strength, good fatigue resistance, dimensional stability, and low creep.
Prone to hydrolysis under high temperature and high humidity conditions; thorough drying is required before molding.
