Cellulose Ethers Tailored for Customers in Various Fields

Celotech company has established several application labs at demestic and abroad. Through repeated
experiments, we ensure the quality of each batch of cellulose ether, starch ether, RDP and other products,
which greatly reduces the unqualified rate of finished products.

Professional Cellulose Ethers Manufacturing

With a full set of professional feeders, feed distributors, etherification reactors, granulators and pneumatic conveyors, Celotech produces more uniform cellulose ethers with finer particles. It shows excellent stability in cement, concrete and gypsum, especially in products such as dry-mix mortars, detergent, oil-drilling and paint & coatings.

High stability chemical additives are specially designed for harsh environments and climates.

Cellulose ethers have long been used as additives in a variety of formulations, including construction chemicals, pharmaceuticals, food, and personal care products. Its versatility lies in its ability to enhance texture, stability, and functionality in a variety of applications.
