Product Description

Product Description:
This product is formed by the degradation of polyacrylonitrile under high temperature and high pressure. Its main components include carboxylic acid, carboxy group, amide group and ammonium group. Its particles are not easy to agglomerate. The product has strong functions of reducing the filtration loss of drilling fluid, high temperature and high pressure filtration loss, strong temperature resistance, good thermal stability, etc., and has certain ability to inhibit clay hydration and collapse, and has good salt resistance and pollution resistance.
