制備的PVDF溶液的變色是由于溶劑的高含水量,并且還可能導致一些氫氧化鋰掉入。鋰在PVDF上取代了F.PVDF是聚偏二氟乙烯。它的外觀是半透明或白色粉末或顆粒。分子鏈緊密排列并具有強氫鍵。氧指數為46%,不燃,結晶度為65%~78%,密度為1.77~1.80g/cm3,熔點為172℃,熱變形溫度為112~145℃,長期使用溫度為-40~150°C。它結合了氟樹脂和通用樹脂的特性。它具有良好的耐化學性,耐高溫性,抗氧化性,耐候性和耐輻射性。它還具有壓電性,介電性能,熱電性等。特殊性能是氟塑料生產中的第二大產品。 。以上文獻若需轉載請備注出處:pbt塑料 //shanglikaiguan.cn/
