        PVC硬片的基本構成與生產(chǎn)工藝

        2024-06-14

        PVC硬片,即聚氯乙烯硬質(zhì)片材,是一種廣泛應用的塑料材料,因其物理和化學(xué)性質(zhì),在包裝、建筑、廣告、電子等多個(gè)領(lǐng)域扮演著(zhù)重要角色。由天成PVC硬片廠(chǎng)家總結一下PVC硬片的基本構成與生產(chǎn)工藝。

        PVC硬片主要由聚氯乙烯樹(shù)脂加入增塑劑、穩定劑、潤滑劑、填料等助劑混合后,通過(guò)擠出成型或壓延工藝制成。其中,不tian加或少量添加增塑劑是其成為“硬片”的關(guān)鍵,這使得制品具有較高的硬度和剛性。
