PC/ASA (polycarbonate/acrylic-styrene-acrylate)
Description (definition)
PC/ASA (polycarbonate/acrylic-styrene-acrylate) is a thermoplastic blend that combines the impact resistance, heat resistance and strength of polycarbonate (PC) with the weathering and UV resistance of ASA. This blend is particularly suitable for applications that require high mechanical stability and resistance to environmental influences, such as outdoors or in demanding technical applications.
Example
A typical example is the use of PC/ASA in housings for exterior lights or automotive parts such as exterior mirror housings. The UV resistance ensures that the components retain their color and strength even after years of exposure to sunlight.
What advantages does PC/ASA offer over PC/ABS?
PC/ASA is significantly more weather and UV resistant than PC/ABS, making it ideal for outdoor applications. It combines these properties with the high impact strength and heat resistance of PC.
Where is PC/ASA frequently used?
PC/ASA is used in the automotive industry for exterior mirror housings, trim strips and spoilers as well as in the electronics industry for outdoor housings, lamp housings and components. It is also used in garden furniture and other durable consumer goods.
Is PC/ASA recyclable?
Yes, PC/ASA can be recycled. However, the process is technically challenging as the properties of the blend must be retained. Recycled PC/ASA is often reused in less critical applications.
