Product description

Polyimide,which contains imide ring, is a kind of high molecular polymer. ASPIpolyimide fiber is developed and produced by Jiangsu Aoshen New Materials Co.,Ltd. The fiber is manufactured through dry spinning technology and has goodmechanical properties and excellent properties of high temperature resistance,flame retardant resistance, radiation resistance and decay resistance.

Thefilament is available for high-end filtration base cloth, insulating sheath ofcables, tensile cable of satellite antenna and special woven compositematerial.
