HP cellulose is a high molecular polymer with a macromolecular linear structure and hydroxyl groups on the functional groups, which can form hydrogen bonds with the mixing water molecules to increase the viscosity of the mixing water. The long molecular chains of HP cellulose attract each other, making HP cellulose molecules intertwine to form a network structure, which wraps the cement and mixing water. Due to the network structure similar to the film formed by HP cellulose and its wrapping effect on cement, it can effectively prevent the evaporation of water in mortar and hinder or slow down the hydration speed of cement.

One of the primary applications of MHEC in the pharmaceutical industry is as a binder in tablet formulations. Tablets are a popular dosage form due to their convenience and ease of administration. MHEC acts as a binder by providing cohesion and adhesion to the tablet ingredients, ensuring that the tablet maintains its shape and integrity. This is particularly important for tablets that are intended to be swallowed whole, as they need to withstand the forces exerted during swallowing.
