When Sony prepared random copolymer of VDF and HFP which had molecular weight equivalent to that of PVDF having a melting point of 175 °C, properties of this copolymer were intermediate between the crystalline nature of PVDF and the pliant nature of PHFP and thus its melting point was around 130 140 °C, considerably lower than that of PVDF.
