Excellent heat resistance with a continuous use temperature of 288°C. Outgassing is also reduced. Material property table and price list are being distributed [Remote consultations are also available].

"Besper" is a DuPont manufactured fully aromatic polyimide resin that boasts exceptional heat resistance, capable of supporting high loads without softening even at high temperatures. In addition to "SP-1," which is made of 100% polyimide resin and excels in mechanical strength and electrical and thermal insulation properties, we offer a variety of grades that can be selected based on application needs, including sliding properties, static elimination performance, and dimensional stability under high loads. 【Features】 ■ Continuous use temperature is 288°C, intermittent use temperature is 480°C ■ Low outgassing, making it suitable for environments requiring high cleanliness, such as the semiconductor field ■ Prevents damage to transported items when used in transport rollers ■ "SP-1" can be used for insulation parts, insulating components, valves, glass substrates, lenses, bearings, transport suction nozzles, seal rings, and plasma-resistant parts. *We are currently publishing a property table that includes "SP-1" and "SCP-5000 (high strength and chemical resistance)," as well as a price list for "SP-1" and "SP-202 (static elimination grade)."
