Polyanide film is a high -temperature -resistant motor electrical insulation material with yellow transparent color. It is mainly divided into two types: average benzene polypelide film and plybinyl polylide film. It has prominent high temperature resistance and resistance Radiation, chemical corrosion and electrical insulation performance can be used for long -term air in 250-280 ° C.
1. The chemical properties of polytamide film
Polyamide chemical properties are stable. Polybamide does not require flame retardant to prevent burning. General polytamide anti -chemical solvents such as hydrocarbons, esters, ether, alcohol, and fluorophylene. They also resist weak acids but are not recommended to use in strong alkali and inorganic acid environments. Some polytide, such as CP1 and CORIN XLS, are soluble in solvents, which helps develop their applications in spraying and low -temperature cross -linking.
Second, the physical properties of polytamide film
Thermosetric polytamide has excellent thermal stability, chemical corrosion resistance and mechanical properties, and is usually orange. The cornering strength of the enhancement of graphite or glass fiber can reach 345 mPa, and the curved modulus reaches 20gPa. The thermosetry polytamide creep is very small and has a high tensile strength. The temperature range of polyimide covers a wide range, ranging from minus 100 degrees to two or three Baidu.
