石蜡是从某些石油、页岩油或其他沥青矿物油的馏分中提取的。它是一种无味无臭的烃类混合物，呈白色或浅黄色半透明固体。还有人造石蜡。
石蜡是一种石油加工产品，一种矿物蜡，也是一种石油蜡。用于制造高脂肪酸、高级醇、火柴、蜡烛、防水剂、药膏、电绝缘材料等。

石蜡的特性

Paraffin wax is a mixture of hydrocarbons, so it does not have a strict melting point like pure compounds, melting at 47°C-64°C. All kinds of wax products require paraffin wax to have good temperature resistance, that is, it does not melt or soften and deform at a specific temperature.

According to the use conditions, the regions and seasons of use, and the differences in the use environment, commercial paraffin waxes are required to have a series of different melting points to meet varied practical demands.

For example, waxes used in warmer climates or during summer generally need higher melting points so they remain stable and effective in elevated temperatures, while those used in colder regions or winter conditions may require lower melting points to maintain flexibility, spread evenly, and deliver proper performance.

石蜡的用途

原油石蜡含油量高，主要用于制造火柴、纤维板、防水布等。完全精炼的石蜡和半精炼的石蜡用途广泛，主要用于食品、口服药物、蜡纸、蜡笔、蜡烛、复写纸成分和包装材料，也用于水果保鲜、电气元件绝缘、改善橡胶抗老化和增加柔韧性等。
