Acrylamide crystals is manufactured with the original carrier-free biological enzyme catalytic technology by Tsinghua University. With the characteristics of higher purity and reactivity, no copper and iron content, it is especially suitable for high molecular weight polymer production. Acrylamide is mainly used for the production of homopolymers, copolymers and modified polymers that are widely used in oil field drilling, Pharmaceutical, metallurgy, paper-making, paint, textile, water treatment and soil improvement, etc.
