PI Product Description
Polyimides are a family of some of the most heat and fire-resistant polymers known. Its excellent retention of mechanical and physical properties at high temperatures is due to the nature of the aromatic raw materials that are building blocks of the polyimides.
Polyimides are formulated as both thermosets and thermoplastics. Moldings and laminates are generally based on thermoset resins, although some are made from thermoplastic grades. Unlike most plastics, polyimides are available as laminates and shapes, molded parts, and stock shapes from some producers and as resins from others.
Electrical properties of polyimides are outstanding over a wide range of temperatures and humidity conditions. Polyimide parts are also unaffected by exposure to dilute acids, aromatic and aliphatic hydrocarbons, esters, ethers, alcohols, freons, hydraulic fluids and kerosene.
PI can keep high physical mechanical properties when in the temperature -269-400 centidegrees, meanwhile it can be used in the air where the temperature ranging from -240-260 centidegrees.
