Hexadecanedioic Acid CAS 505-54-4

Hexadecanedioic Acid is a white crystalline powder, slightly soluble in water. As a long-chain dibasic acid, it is mainly used in the synthesis of high-performance polyester, nylon and lubricant additives, giving materials flexibility and heat resistance. Its environmentally friendly properties are suitable for use in bio-based polymers, but it needs to be handled in a dust-proof manner to keep it away from inhalation or skin contact.
