Construction‑Grade HPMC, also named Hypromellose (Hydroxypropyl Methylcellulose), is an essential functional additive specially developed for dry‑mix building material systems. Produced from high‑quality refined cotton raw materials, the product features stable chemical performance under regular storage and construction conditions. Its gel temperature ranges from 50℃‑90℃ according to different grades, which perfectly adapts to diverse construction environment requirements.
Our HPMC powder serves mortar factories and engineering projects globally. Available viscosity covers 40000‑200000cps (2% Brookfield aqueous solution). Custom grade options are supported to match your unique mortar formula demands.
Good vertical suspension performance. Effectively prevent mortar sagging and falling off on wall and ceiling surfaces. Suitable for hand trowel construction as well as machine sprayed plastering operations.
Excellent water retention performance. Slow down water evaporation during construction, guarantee full hydration reaction of cement and gypsum components, reduce wall defects caused by rapid water loss.
Low‑ash formulation performance. Ash content controlled ≤2.0%, will not introduce excess impurities into finished dry‑mix products, protect the final strength and surface effect of mortar.
Flexible gel‑point characteristic. Different gel temperature grades cope with high‑temperature summer construction and normal‑temperature working scenarios, keep stable working time of mortar.
Outstanding mixing compatibility. Can be evenly blended with cement, gypsum, lime and other common building raw materials, without abnormal agglomeration or stratification in mixed system.
Easy cold‑water dispersion. Convenient for factory batching and on‑site mixing work, lower operation difficulty for mortar producers.
This construction‑grade HPMC is widely used in manufacture of various dry‑mix building products:
Interior and exterior wall putty, wall surface finishing mortar
Masonry mortar, tile adhesive and tile grout materials
Gypsum plaster, gypsum repairing and leveling products
Machine spray plastering dry‑mix compounds
External wall thermal insulation and protective mortar
