Protective film RPP

stretchpolypropylenefor the electronics industry

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: • Significant distinct of roughness between normal surface and roughenized surface, •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. Mainly used for making high voltage power capacitors with oil-impregnat, which needs small space factor (SF).
