PBT/ASA (polybutylene terephthalate/acrylic styrene acrylate)
Description (definition)
PBT/ASA is a thermoplastic blend that combines the strength, heat resistance and chemical resistance of polybutylene terephthalate (PBT) with the weathering resistance and UV stability of acrylic-styrene-acrylate (ASA). This compound is ideal for applications that require mechanical strength and long-term resistance to environmental influences, especially outdoors.
Example
A typical example of the use of PBT/ASA is in housings for outdoor electrical equipment, such as charging stations for electric vehicles. The combination of weather resistance and stability ensures durability under demanding conditions.
What advantages does PBT/ASA offer over pure PBT?
In addition to the properties of PBT, PBT/ASA offers improved UV and weather resistance, making it more suitable for outdoor applications. It also retains its mechanical stability even under changing climatic conditions.
For which applications is PBT/ASA used?
PBT/ASA is often used in the automotive industry for exterior components such as trim strips or mirror housings and in electronics for weatherproof housings for outdoor devices. It is also used in the construction industry, e.g. for façade components.
Is PBT/ASA recyclable?
Yes, PBT/ASA can be recycled. However, reuse is challenging due to the material mixture. Recycled PBT/ASA is often used in technical applications that do not require high-precision material properties.
