It is stretched in biaxial orientation by means of flat film method by using ultra-high purity homopolymerized polypropylene resin in capacitor grade. It is characterized by the following:
• Double sides of film are roughenized,
•Good thickness uniformity,
• Good homogeneity of space factor(SF),
• High voltage strength,
• Low dissipation factor.
• Excellent compatibility with a variety of capacitor impregnation,
• Easy to wind.
