Properties of MHEC
The glass transition temperature for HPMC varies based on its molecular weight and substitution level. Generally, lower molecular weight grades of HPMC exhibit lower Tg values compared to their high molecular weight counterparts. This variance arises because lower molecular weight materials possess fewer entanglements among polymer chains, leading to enhanced molecular mobility at lower temperatures. As a result, the Tg of HPMC can range from approximately 50°C to 120°C. Understanding this range enables manufacturers to select the appropriate grade of HPMC for specific applications, ensuring the material performs effectively under operational conditions.
