High Purity Redispersible Polymer Emulsion Powder RDP for Construction
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.
we could offer OEM service according to customers requirement.
Methyl Hydroxyethyl Cellulose is a white, yellow-white or off-white powder or granules, hygroscopic after drying. It is a methylcellulose based cellulose. It has several properties used in the pharmaceutical and construction industries. Methyl Hydroxyethyl Cellulose (MHEC) alone or in combination is the most widely used cellulose in mortar formulations. MHEC has various properties such as thickening, emulsifying, binding, forming, protective colloid and water retention.
