The base of Bermocoll products is cellulose, one of the the world's most common natural polymers.
In Bermocoll EHEC, the hydroxyl groups of the cellulose are modified with ethyl and hydroxyethyl substituents. The properties of cellulose ethers are determined by the type of substituents, and also by their number and distribution along the molecule chain.
Bermocoll MEHEC is a methyl ethyl hydroxyethyl cellulose. The number of methyl groups corresponds closely to those found on MHPC or MHEC grades currently available. In addition, low amounts of ethyl and hydroxyethyl substitution are present on the molecule.
The chemical modification results in significantly changed characteristics with regard to solubility, surface activity, chemical resistance and enzyme resistance. In this way, it is possible to produce sets of cellulose ethers with carefully calculated performance characteristics.
We have a strong RD&I organization with the capabilities to maximize the benefits of Bermocoll in your application.
