Applications of PBT Injection Molding
Although PBT does not feel as smooth as ABS and has poorer light transmission compared to ABS, PBT has carved out a niche in the keycap market against ABS keycaps thanks to its superior durability and oil resistance.

The modifications of PBT mainly include flame-retardant PBT, glass fiber-reinforced flame-retardant PBT, and glass fiber-reinforced PBT. PBT is commonly blended with PC to form alloys used in automotive parts, with PC/PBT often utilized for car bumpers. Additionally, modified PBT can be used for car window motor housings, motorcycle motor parts, and automotive transmission gearboxes.
