High temperature long-term working temperature 310 ℃, instantaneous resistance by temperature up to 760 ℃. 2. corrosion in acid environment remains stable characteristics. 3. High-intensity strength is twice Vespel products, the highest intensity of existing engineering plastics products. The high hardness, the hardness half glass. 5. High-purity ash can be controlled below 2ppm. Applied to the semiconductor industry, specialty glass industry, high performance requirements for plastics for use. PBI Performance: air, the maximum allowed high temperature (400 degrees can continue to work, short-term maximum temperature up to 500 degrees). Excellent retention of mechanical strength and stiffness, excellent wear and friction properties, low linear thermal expansion coefficient, the inherent low flammability, high purity ionic contamination environment, low exhaust resistance (dry material). Applications: Typically used to make very demanding of components to reduce maintenance and repair costs, and the longest life. Applications have been established semiconductor and aerospace industries, incandescent or fluorescent hot contacts, such as vacuum cups, pushing means and cage, electrical contacts and so on. The disadvantage is the lack of capacity of high temperature steam, slow performance after absorbing moisture.
