KimaCell®HPMC E4000 is hydroxypropyl methyl cellulose ether for ceramics. Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose ether made from natural polymer material cellulose through a series of etherification. It is an odorless, tasteless and non-toxic white powder that swells into a clear or slightly cloudy colloidal solution in cold water. It has the characteristics of thickening, dispersing, emulsifying, film-forming, suspending, adsorbing, surface active, maintaining moisture and protecting colloid, etc. It is mainly used in building materials, coating industry, synthetic resin, ceramic industry, textile, agriculture, daily chemical and other industries.

In the ceramic industry, KimaCell® HPMC E4000 is used as a binder for molding surprise ceramic products, imparting lubricity, water retention, and improving the original strength of raw materials. The concentrated solution is adsorbed on the surface of the ceramic particles, which reduces the friction between the particles and enhances its lubricity, so that the molded products obtained have the required surface finish and dimensional stability; the HPMC product with low ash content can be used Sintered ceramic products with excellent electrical properties are obtained.
Adding HPMC to ceramic products can achieve:
The operability of mold tires for ceramic products.
Good green body strength of ceramic products.
Good lubricating performance, which is beneficial to extrusion molding.
The surface is round and delicate.
Ceramic products have a very dense internal structure after burning.
