Long-Chain Dibasic Acids

1. Long-Chain Dibasic Acids Production

   Junheng biotech (Palmary Chemical supplier) produce a wide variety of high-quality long-chain dibasic acids using bioprocesses. Our dibasic acids are produced from paraffin through fermentation followed by purification, rather than the traditional multi-step chemical process. 
    On the basis of raw material of long chain dicarboxylic acids to produce synthetic nylon resin, senior spice musk-T, senior nylon plastic, high temperature electrolyte, high-grade copolymer polyamide hot melt, cold-resistant plasticized agents, advanced lubricants, high-class paints and coatings, are widely used in chemical industry, light industry, pesticide, medicine, liquid crystal materials and other fields.
