Hydroxy propyl Methyl Cellulose in ceramic applications, mainly plays the following roles:
Adhesive: HPMC has good adhesive properties, which can firmly bond ceramic powder together to form a uniform porcelain body.
Plasticizer: HPMC has good plasticizing properties, which can make ceramic materials more flexible and easy to shape during the molding process.
Dispersant: HPMC can effectively disperse ceramic powder so that it can be more evenly distributed throughout the porcelain body, thereby improving the quality of the porcelain body.

Stabilizer: HPMC can improve the stability of ceramic materials so that they can still maintain good physical and chemical properties at high temperatures.
