HPMC E6000

KimaCell®HPMC E6000 is hydroxypropyl methyl cellulose ether for ceramics. Different amounts of powdered hydroxypropylmethylcellulose (HPMC) and starch were used as binders in the extrusion of silicon nitride green bodies. Their three-point bending strength and the microstructure of the fracture surface were investigated. It was found that HPMC can significantly increase the green strength compared to the use of starch. Adding 10% HPMC has a flexural strength of 29.3±3.1 MPa, which is about 7.5 times that of similar starch materials. The significant increase in strength was attributed to the coarse, fibrous HPMC particles that aligned along the extrusion direction and were pulled out during the bending test. This work represents a simple yet effective method to extrude high-strength ceramic green bodies.

Application of HPMC E6000

In the ceramic industry, KimaCell® HPMC E6000 is used in Ceramic fiber-reinforced high-temperature-resistant gas filter material can balance strength and porosity, and can improve the mechanical strength of the filter material on the basis of ensuring good filtration performance.

High temperature filter material is the core component to realize high temperature gas filtration and dust removal. Both high-density and low-density ceramics can be used as filter media. Common high-density ceramics are made of silicon carbide, alumina or cordierite materials, and low-density ceramics are mainly made of aluminosilicate fibers. Low-density ceramic filter materials have the characteristics of high porosity, low filtration resistance, and good fracture toughness. However, due to the loose nature of the fibers, their mechanical strength is low, which increases the risk of damage to filter cartridges. Although high-density ceramics have high mechanical strength, they have high filtration resistance, and there is a mutual restrictive relationship between porosity and strength, and the specific gravity is relatively large, which increases production, installation and transportation costs.
