The role of hydroxypropyl methyl cellulose in insulation materials

Hydroxypropyl methyl cellulose (HPMC) is widely used in building materials, and it has the following characteristics for external wall insulation:

Bond strength:

Choosing the appropriate cellulose can provide the highest bond strength mortar;


In the application method, the mortar added with cellulose has a certain consistency and does not sag. Make the mortar work continuously in the application;

Water retention:

It is easy to heat the wall, easy to paste, so that other additional materials can achieve the best effect;


Adding hydroxypropyl methyl cellulose during construction can reduce the air inlet of the mortar and reduce the water absorption rate.
