Engineering Plastics are divided into thermoplastic and thermosetting resin two major categories. Thermoplastic polyimide materials have been widely used in this kind of high-performance materials because of their non melting properties. and thermosetting Engineering Plastics melt Excellent processing and molding performance and high-performance in one. Which, polyimide special Engineering Plastics has a high glass transition temperature (243 ℃) and melting point (334 ℃), load heat variant temperature up to 316 ℃, can be used in 250 ℃ long-term; pi resin not only heat resistance than other high-temperature plastic excellent, but also has high strength, modulus, High fracture toughness and excellent dimensional stability.
