GH9 is a new type of sodium carboxymethyl cellulose developed by our company. GH9 boasts excellent fluidity with a viscosity of 1000~1200, strong resistance to both acids and alkalis, and its aqueous solution can be fully dispersed through a 300 mesh standard sieve. The substitution degree and purity meet imported standards, effectively solving problems such as excessive sedimentation during sieving and instability of viscosity over prolonged storage, gaining wide recognition from customers in the ceramic printing glaze industry.
