    季戊四醇四硬脂酸酯(PETS)

    关于此产品

    PETS 亦称 pentaerythrityl tetrastearate,是一种多元醇酯,季戊四醇的全部四个羟基均与硬脂酸酯化,分子式为 C77H148O8。它被描述为纯度 99% 的白色结晶粉末,典型熔程为 50–70 °C,溶于乙醇和苯,不溶于水。

    在热塑性工程塑料中,它用作润滑剂和分散剂。在玻纤增强复合料中,它有助于纤维在树脂中分散和粘合,减少表面浮纤并提高光泽度;其在加工温度下的失重低,适合高温配混。其他用途包括润滑油配方,以及金属切削和薄钢板轧制的润滑。

    酸值、羟值和色度限值通常属于 PETS 规格的一部分,但此处未注明,因此订购前请商定这些指标及物理形态,因为该产品也被描述为白色蜡状固体。熔程为典型值而非批次限值,因此请将每批交货与其批次证书进行比对,并在使用前备妥 SDS。
