4-Hydroxybenzoic acid is mainly used as a basic raw material for fine chemical products, while parabens, also known as p-hydroxybenzoic acid esters, have been widely used as preservatives in food, medicine, and cosmetics. They are also widely used in the preparation of various dyes, fungicides, color film, and various oil soluble color couplers. The new high-temperature resistant polymer p-hydroxybenzoic acid polyester, which has a wide range of applications, is also used as a basic raw material.
Usually packed in 25kg/drum,and also can be do customized package.
