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.

I.PI 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. 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.
