Polyimide parts
Polyimide parts
1. It has excellent heat resistance. It can be used continuously at 288°C and intermittently at 480°C. 2. It has excellent abrasion resistance. The limit PV value is more than ten times that of general plastics. 3. It has excellent creep resistance. Creep at 260°C and 18.2MPa is only 0.6% after 1000 hours. 4. It has 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.
basic information
Bespel SP is a general term for parts molded from a powder of fully aromatic polyimide resin developed by DuPont using advanced technology. Bespel SP has the highest heat resistance and wear resistance among high-performance resins currently on the market and in mass production. Since its commercialization in 1962, it has been widely used in parts for the aerospace, space, and military industries, and today it is also used in automobiles, office automation equipment, electronics, electrical equipment, scientific instruments, industrial machinery, and production equipment.
