One of the challenges with cellulose is its resistance to degradationcellulosecellulose . This is both a benefit and a drawback, depending on the context. The resilience of cellulose makes it an excellent material for long-lasting products such as paper and textiles. However, its slow decomposition in the environment can contribute to the buildup of waste in landfills. Finding sustainable ways to recycle and reuse cellulose-based materials is an ongoing area of research and development.

Shijiazhuang Yongfeng hydroxypropyl methyl cellulose ‎(hpmc)

In general, the gel temperature of HPMC is around 60℃-75℃ depending on its group content and different production technique. Due to the characteristics of MHEC group, it has a higher gel temperature, usually > 80℃. Therefore its stability under high temperature is better that HPMC. In practical construction, in the hot construction environment in summer, the water holding capacity of MHEC with the same viscosity and dosage is better than that of HPMC. Especially in the Southeast Asian countries and India, mortar will sometimes be constructed at high temperature. Cellulose ether with low gel temperature will lose its thickening and water retention at high temperature, thereby accelerating the hardening of mortar, and affects the construction.
