PBT/PET (polybutylene terephthalate/polyethylene terephthalate)
Description (definition)
PBT/PET is a thermoplastic blend that combines the mechanical strength and heat resistance of polybutylene terephthalate (PBT) with the chemical resistance and surface quality of polyethylene terephthalate (PET). This blend is often used for technical applications that require high dimensional stability, durability and visually appealing surfaces.
Example
A well-known example is the use of PBT/PET in automotive parts such as sensor covers and technical housings, where both stability and a high-quality appearance are required.
What advantages does PBT/PET offer over pure PBT or PET?
PBT/PET combines the mechanical stability and heat resistance of PBT with the improved surface quality and chemical resistance of PET. The result is a material that is versatile and particularly robust.
How is PBT/PET used in the electronics industry?
In the electronics industry, PBT/PET is used for connectors, housings and components that require precision and high insulation properties. Its low water absorption ensures reliable dimensional stability.
Is PBT/PET environmentally friendly?
PBT/PET is recyclable and can be reused in closed material cycles. This helps to reduce plastic waste and supports sustainable materials management.
