Methyl cellulose and HPMC are two types of cellulose-based polymers commonly used in building materials. However, Methyl Cellulose is gradually being replaced by HPMC due to the higher requirements in modern construction. In addition, some suppliers refer to methyl cellulose as the common name for hydroxypropyl methyl cellulose (HPMC) and Hydroxyethyl methyl cellulose (HEMC). We will explore the difference between HPMC and HEMC in later articles.
Temperature also significantly influences HPMC's solubilityFertigpräparate als „künstliche Tränen“ (Auswahl):
The hydrophilic nature of HPMC means that it can interact with water through hydrogen bonding. When HPMC is added to water, the polar hydroxyl groups on the polymer chain attract water molecules, causing the polymer to hydrate and swell. This process is further facilitated by the thermal motion of water molecules, which helps to separate the individual HPMC chains and promote their dissolution.
