Types of Polyarylate
Unfilled Polyarylate: This is the base form of Polyarylate, offering good dimensional stability, high heat deflection temperature, and exceptional electrical properties. It is transparent and inherently UV resistant, making it ideal for optical applications.
Glass-filled Polyarylate: To enhance the mechanical strength and stiffness, Polyarylate can be filled with glass fibers. The addition of these fibers increases the heat deflection temperature and reduces the material’s overall shirinkage
Applications
Polyarylates are extensively used in optical applications such as lens covers for outdoor lighting fixtures, automotive light covers, eyewear, and more.
electrical and electronic applications. Polyarylates are often used in connectors, sockets, and switches, among other components.They are used in components that need to withstand extreme conditions, such as in the insulation of aerospace wiring.Polyarylates are now finding their place in the medical field due to their biocompatibility, transparency, and high-temperature resistance. They are used in medical devices and in the construction of surgical instruments.
