Besper(R)
Bespel® is a high-heat-resistant plastic (fully aromatic polyimide resin) developed by DuPont. It has the best heat resistance and wear resistance among engineering plastics and is used in a wide range of applications, including mechanical and electrical components. 【Features】 1. Excellent heat resistance. It can be used continuously at 288°C and intermittently at 480°C. 2. Excellent wear resistance. The limit PV value is more than 10 times that of general plastics. 3. Excellent creep resistance. Creep at 260°C and 18.2MPa is only 0.6% after 1000 hours. 4. Excellent electrical properties. Insulation strength is 22KV/mm. 5. Additionally, it excels in plasma resistance, radiation resistance, gas release resistance (under vacuum), and chemical resistance.
