▎ 摘　　要

NOVELTY - Modified polytetrafluoroethylene resin comprises 0.79-0.99 pts. wt. polytetrafluoroethylene, 0-0.1 pts. wt. glass fiber, 0-0.1 pts. wt. polyimide and 0.01 pts. wt. fluorinated graphene. USE - Used as modified polytetrafluoroethylene resin. ADVANTAGE - The modified polytetrafluoroethylene resin: has high electric insulation, low linear expansion coefficient, high mechanical strength and excellent wear resistance; and has reduced average linear expansion coefficient in the order of 105/ degrees C magnitude at 40-60 degrees C.
