Product Description
Product Description
Aromatic polyimide (polyimide , PI ) is the best overall performance of one of the organic polymer materials, it has corrosion resistance, fatigue resistance, high temperature resistance, abrasion resistance, impact resistance, low density, low noise, long service life, etc., as well as excellent performance in high and low temperatures (long-term -269 ℃ to 280 ℃ invariance); thermal decomposition temperature can be as high as 600 ℃, is the polymer in the heat stability so far Thermal decomposition temperature can be as high as 600℃, which is one of the highest varieties of polymers in thermal stability so far, and will not be brittle in liquid helium at -269℃. It has been widely used in aerospace, aviation, space, automobile, microelectronics, nano, liquid crystal, separation membrane, laser, electrical appliances, medical devices, food processing and many other high-tech fields, and is known as the “problem solver”.
Polyimide is a high-performance thermoplastic engineering plastics, not only has excellent heat resistance, mechanical, dielectric, corrosion resistance and radiation resistance and other properties, but also shows excellent thermal processing properties, can be hot molding, extrusion and injection molding methods.
Polyimide can be compounded with glass fiber, carbon fiber, PTFE, graphite, etc., which significantly improves the mechanical properties and self-lubricating properties of polymer materials.
Polyimide can be made into films, can also be molded into tubes, rods and complex structures of confidential parts, such as gears, sealing rings, bearings and connectors. In specific cases for a replacement of metals, ceramics, thermosetting resins, low-temperature thermoplastics and most difficult to heat processing molding polyimide ideal materials.
