Dodecanedioic Acid (DDDA) is a highly pure C12 dibasic acid that is available in white flake form. This product is commonly used in adhesives, corrosion inhibitors, capacitor electrolytes, diester synthetic lubricants, fibers, powder coating curatives, plasticizers, polyester coatings, epoxy resins, and polyamide resins.
Dibasic Acids are a family of organic compounds with a chemical formula of HOOC(CH2)nCOOH. These compounds are known as 'long-chain dicarboxylic acids' when the total carbon number is greater than nine (n>7). Long-chain diacids provide greater flexibility and strength than short-chain diacids due to their ability to bend, which minimizes breakage and reduces the number of links in a polymer.

We produce a wide variety of high-quality long-chain diacids using bioprocesses. Our diacids are produced from paraffin through fermentation followed by purification, rather than the traditional multi-step chemical process. This production method has a simple process and can completely replace the chemical synthesis method which is high temperature, high pressure, flammable and explosive, pollutes the environment, expensive and has been blocked from China for many years.This technology will allow for the introduction of renewable versions of many commercialized products.

Except for Dodecanedioic acid, we also offer the following types of long chain diacids:  UndecanedioicAcid ,Sebacic Acid ,Brassylic Acid ,Tetradecanedioic Acid , Pentadecanedioic Acid ,Hexadecanedioic Acid .
 
Application: Lubricant ,High-performance polyamide / nylon, powder coating, adhesive, perfume, rust prevention
