Poly(butylene terephthalate) CAS# 26062-94-2
Excellent Mechanical Strength and Dimensional Stability: PBT resin provides high rigidity, strength, and dimensional accuracy, making it suitable for precision structural parts in automotive, electrical, and mechanical applications.
Superior Heat and Flame Resistance: When reinforced with glass fibers and flame retardants, PBT demonstrates excellent thermal stability and flame-retardant performance, meeting the safety requirements of electronic and electrical components.
Outstanding Processability and Versatility: PBT can be easily blended with other polymers to form plastic alloys, allowing performance customization for different applications, especially in the automotive industry.
High Temperature Resistance and Broad Application Range: PBT and its alloys can withstand elevated temperatures, enabling their use in demanding environments such as automotive ignition systems and food-grade containers suitable for microwave heating above 160°C.
Polybutylene terephthalate (PBT) resin is widely used in structural components in the automotive, electronics, electrical, machinery, and instrumentation industries. Glass fiber reinforced PBT with added flame retardants is extensively used in flame-retardant components for televisions, such as the frame and base of output transformers, and connectors for various electrical appliances (chemicalbooks and switches). PBT can be blended with other polymers to create plastic alloys, with the largest market being the automotive industry, used for components such as car bumpers and ignition systems. These alloys are also increasingly being used in the food industry, for example, in the manufacture of microwave oven heating containers that can withstand temperatures above 160°C.
