The Performance Of HPMC In Honeycomb Ceramics

The Performance Of HPMC in Honeycomb Ceramics

Hydroxy Propyl Methyl Cellulose (HPMC) is a nonionic cellulose ether polymer. Depending on the degree of substitution of the substituent groups and the degree of modification, they exhibit different chemical properties， applicable to building materials, industrial coatings, ceramics, textiles, agricultural chemicals, and other fields.

Honeycomb ceramics are widely used in power generation desulfurization and denitrification, and automotive exhaust treatment. HPMC plays a crucial role in the production of thin-walled honeycomb ceramic , significantly contributing to the shape preservation of the green body.

The performance of HPMC in honeycomb ceramics:

1. HPMC improve the operability of honeycomb ceramic molds;

2. Adding  HPMC gives honeycomb ceramic products better green body strength;

3. HPMC have good lubricity, which is beneficial for honeycomb ceramic extrusion molding and improves product qualification rate;

4. HPMC make honeycomb ceramic products round and delicate;

5. HPMC give honeycomb ceramic products a very dense internal structure after combustion;

6. Adding HPMC in honeycomb ceramics has a significant shaping effect on the green body, ensuring product dimensional accuracy, uniform wall thickness, and reducing scrap rate.
