Construction Grade - HPMC
Dongyuan Shengda is a reputable cellulose ether manufacturer that provides high-performance construction-grade HPMC (Hydroxypropyl Methyl Cellulose) for modern building materials. This non-ionic cellulose ether, produced by alkalizing and etherifying cellulose, is commonly used in dry-mix mortar, putty powder, gypsum products, tile adhesives, plastering materials, coatings, and self-leveling compounds. Even at low doses of 0.1-1%, HPMC improves water retention, workability, fluidity, adhesion strength, and surface smoothness. It has excellent thickening, dispersing, emulsifying, and film-forming properties, while also increasing open time and construction efficiency. Dongyuan Shengda's construction HPMC is resistant to hydrolysis and UV exposure, ensuring consistent quality, strong compatibility with additives, and dependable performance in humid environments.
Liquid Detergent Grade - HPMC
Dongyuan Shengda is a professional cellulose ether manufacturer that produces high-quality, daily chemical-grade HPMC (Hydroxypropyl Methyl Cellulose) for detergents and personal care products. HPMC is used as an effective thickener and stabilizer in laundry detergents, dishwashing liquids, hand sanitizers, cleaners, shampoos, and shower gels, ensuring uniform particle suspension and preventing settling. It enhances product appearance and consistency by providing over 90% transparency and a quick dissolution time of 3-5 minutes. This white to slightly yellow powder, made from natural cellulose, has excellent viscosity control, foam stabilization, easy dispersion, and film-forming properties. It is non-toxic, irritant-free, allergen-free, and highly compatible with a variety of everyday chemical additives.
