Physical properties: Stearic acid, also known as octadecanoic acid, a fatty acid without unsaturated bonds, is produced by hydrolysis of oils. White or slightly yellow crystalline powder, it becomes a transparent liquid after melting.

用途：主要用于制造各種硬脂酸鹽類、橡膠助劑等。在橡膠的合成和加工過程中起重要作用，是天然膠、合成橡膠和膠乳中廣泛應用的硫化活性劑，也可用作增塑劑和軟化劑。在生產合成橡膠過程中需加硬脂酸作乳化劑，在制造泡沫橡膠時，硬脂酸可作起泡劑，硬脂酸還可用作橡膠制品的脫模劑。

Uses: Mainly used in the manufacture of a variety of stearic acid salts, rubber auxiliaries, etc.. It plays an important role in the synthesis and processing of rubber. Stearic acid is a widely used vulcanizing active agent in natural rubber, synthetic rubber and latex, and can also be used as a plasticizer and softener. In the production of synthetic rubber, stearic acid is used as emulsifier, in the manufacture of foam rubber, stearic acid can be used as a foaming agent, stearic acid can also be used as a mold release agent for rubber products.
