High Tensile Strength PBT Glass Fiber Polymer Wide Applications

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.

Long Carbon Fiber vs. Short Carbon Fiber Composites

Applications
PBT-LGF reinforced with long glass fiber:
Automotive structural components – such as engine covers, water pump housings, oil separators, where heat resistance and mechanical durability are critical.Structural housings of power toolsAutomotive structural parts such as battery trays, door modules, seat frames, and electric drive system supports
Electrical equipment housings that require high temperature resistance and mechanical durability
Industrial machinery components demanding long service life and high fatigue resistance
Lightweight metal replacement structural parts like brackets, frames, and carriers
Metal replacement – for lightweight yet strong alternatives in technical applications.

PBT-SGF reinforced with long glass fiber:
Precision electrical connectors and plugs, including housings and cable clamps
Consumer electronics enclosures like handheld device cases and sensor covers
Automotive interior parts and small functional components such as button covers and air vent parts
Household appliance components including heater housings, dryer parts, and internal supports
