Abstract: Many special polymer materials were developed ＆ applied in Chinese aerospace industry by Aerospace Research Institute of Materials and Processing Technology( ARIMPT) since its establishment 55 years ago，and most of them had been in series． The materials it has been developed cover more than 80 kinds of elastomeric sealing materials，including carboxy nitroso fluororubber ＆ fluoroether rubber for N2O4，ethylene-propylene rubber for unsymmetrical dimethyl-hydrazine，silicone rubber for satellites ＆ spacecrafts，and about 100 kinds of silicone，chloroprene，nitrile damping rubbers; and modified PA，PU，PPS，PI，PEEK，PTFE，PMI engineering plastics for subsidiary construction; and TL series environmental protection coatings，XB ＆ TF series spacecrafts survival ＆ penetration coatings，TR series thermal resistant coatings，space thermal control coatings，etc; and more than 100 kinds of special adhesives ＆ sealants for adhesion of thermal protection layer，heat sealing，ultra-low temperature ＆ special media; and high property synthentic resin systems for advanced composite mayerials，i． e． modified epoxy resin，bismaleimide ，cyanate ester，polyimide ＆ other high-temperature resistant resin etc． These polymer materials and the parts made of them had been applied successfully in the launch vehicles，satellites and the spacecrafts of our country．
