HPMC for Honeycomb Ceramic Additives

● ETON cellulose ether can improve the operability of honeycomb ceramic mold tires;

● Adding ETON cellulose ether can make honeycomb ceramic products have better green tire strength;

● ETON cellulose ether has good lubricity, which is beneficial to the extrusion molding of honeycomb ceramics and improves the product qualification rate;

● ETON cellulose ether can make honeycomb ceramic products round and delicate;

● ETON cellulose ether can make the honeycomb ceramic product have a very dense internal structure after combustion;

● The addition of ETON cellulose ether in the honeycomb ceramic has an obvious effect on the shape preservation of the green tire, which can ensure the dimensional accuracy of the product, ensure the uniformity of the wall thickness, and reduce the rejection rate.

Product Details

ETON HPMC(Hydroxypropyl methyl cellulose) is mainly used in the field of honeycomb ceramics. Honeycomb ceramics were first used to purify the exhaust gas of small cars.

Now they have been widely used in chemical industry, electric power metallurgy, petroleum, electronics, electrical appliances, machinery and other industries. With the development of technology, more and more thin～walled honeycomb ceramics are used. HPMC plays an important role in the production of thin walled honeycomb ceramics, and has an obvious shape preserving effect on the green body.

Characteristics of honeycomb ceramics

1. after adding HPMC, the operability of honeycomb ceramic mold can be improved.

2. after HPMC was added, the honeycomb ceramic products had better blank strength.

3. HPMC has good lubricity, which is conducive to the extrusion molding of honeycomb ceramics and improves the product qualification rate.

4. HPMC can make honeycomb ceramic products smooth and delicate.

5. HPMC can make honeycomb ceramic products have a very dense internal structure after combustion.

6. HPMC plays an important role in keeping the shape of honeycomb ceramics, which can ensure the dimensional accuracy of products, ensure the uniformity of wall thickness and reduce the scrap rate.
