Purpose:

Propylene oxide is the third largest acrylonitrile derivative after polypropylene and acrylonitrile. It is mainly used in the production of polyether polyols, propylene glycol and all kinds of non-ionic surfactants. Propylene oxide derivatives are widely used in automotive, construction, food, tobacco, medicine and cosmetics industries. Nearly 100 kinds of downstream products have been produced, which is an important raw material for fine chemical products.

Packaging Specifications:

Propylene oxide shall be packed in a clean, dry tank car with a carbon steel or stainless steel tank material.

Storage and transportation conditions: the use of special tank truck (ship) transportation, or the use of pipeline transportation, should conform to the relevant safety regulations. Propylene oxide should be stored in a cool, well-ventilated special warehouse or storage tank, away from fire, heat sources. The storage temperature should not exceed 25℃, and keep the container airtight.
