Research progress in polypropylene capacitive film materials
This paper reviewed the catalyst,production,and polymerization technologies of polypropylene(PP)capacitor films in terms of their requirement of performance,and also discussed their current research status at home and abroad.The applications and performance requirements of the most widely used biaxially oriented PP capacitor films in the do-mestic and foreign markets were analyzed in particular.Finally,the future development of PP capacitor film materials in China was prospected.
