Adding glass fiber to PBT is a commonly used method to enhance and modify PBT. The bonding force between glass fiber and PBT resin is good. After adding a certain amount of glass fiber to PBT resin, it can not only maintain the original advantages of PBT resin such as chemical resistance and processability, but also greatly improve its mechanical properties and overcome the problems. PBT resin notch sensitivity.

PBT has properties similar to those of PET (polyethylene terephthalate). It is known for its dimensional stability, low moisture absorption, high strength, stiffness, and chemical, UV, and thermal resistance. It is commonly used in automotive fenders and interior trim pieces, power tool housings, and electrical enclosures.
