The polyarylate contains a high-density aromatic ring in the main chain, and has self-extinguishing properties and high heat resistance. This polymer has a low crystallinity and is therefore very transparent. General molding processes such as injection, extrusion, and blow molding can be employed. Its main features are as follows:
(1) The main chain contains a high-density aromatic ring. After heat-strengthening with glass fiber, the heat resistance is high. Under heavy load, the heat distortion temperature is 175 ° C. If the temperature is raised at 10 ° C / min, the weight loss is only 5% at 443 ° C. .
(2) Excellent impact strength, large yield elongation, and good elastic recovery.
(3) Transparent
(4) Large surface hardness
(5) Excellent insulation
