Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose ether prepared by subjecting refined cotton to alkalization, followed by etherification with propylene oxide and chloromethane through a series of reactions. It exhibits excellent dispersibility, emulsifying, thickening, binding, and water-retention properties and is readily soluble in water. HPMC is widely used in various industrial sectors, including construction materials, petrochemicals, textiles, daily chemicals, ceramics, coatings, and synthetic resins.

Hydroxyethyl cellulose (HEC) is a non-ionic, water-soluble cellulose ether, appearing as a white, free-flowing powder that dissolves in both cold and hot water. The product exhibits excellent resistance to acids and alkalis, as well as to electrolytes, providing stable thickening while also offering water retention, suspension, and anti-sagging properties; its aqueous solutions are clear and transparent. It is widely used in interior and exterior latex paints, construction adhesives, gypsum putties, personal care and household cleaning products, oilfield drilling muds, and other industries. HEC boasts superior dispersibility, resists caking, and ensures stable storage. Packaged in sealed 25 kg kraft paper bags, it should be stored in a cool, dry place.

Carboxymethyl cellulose (CMC), also known as sodium carboxymethyl cellulose (as its industrial products often exist in sodium salt form), is a water-soluble anionic polymer compound obtained by chemical modification of natural cellulose (such as cotton linters, wood pulp, etc.). It is one of the most widely produced and used cellulose ether products.

Polyvinyl alcohol is produced via the polymerization of vinyl acetate followed by alcoholysis. It is a white, stable, non‑toxic, water‑soluble high‑molecular‑weight polymer that dissolves rapidly in water to form a stable colloid; water serves as an excellent solvent for it.

Redispersible latex powder is a powdered form produced by spray-drying polymer emulsions, also known as dry‑powder adhesive. Upon contact with water, it rapidly reverts to an emulsion while retaining the same properties as the original emulsion—namely, forming a film upon evaporation of the water. This film exhibits high flexibility, excellent weather resistance, and strong adhesion to a wide range of substrates.

PP fiber, formally known as polypropylene fiber, is a bundle of short monofilaments produced by drawing and modifying polypropylene. It is a specialized crack‑resistance and reinforcement fiber for dry‑mix mortars and concrete. With strong chemical inertness, it does not react with cement or gypsum, exhibits excellent resistance to acids and alkalis, is corrosion‑resistant, and does not rust, making it widely used in crack‑control applications in construction.

Calcium formate, also known as calcium methanoate, is an organic calcium salt formed by the neutralization of formic acid with calcium. It appears as a white crystalline powder, is chlorine‑free and non‑corrosive, and exhibits excellent early‑strength development at low temperatures. It is used in gypsum mortars, cement‑based tile adhesives, and concrete to accelerate setting and enhance early strength, making it well suited for winter construction. With a purity of 98% or higher, it contains minimal impurities, disperses uniformly, and is easy to incorporate.

Hydroxypropyl Starch Ether (HPS)
Hydroxypropyl starch ether (HPS) is a non-ionic, water-soluble polymer compound obtained by chemical etherification modification of natural starches (corn starch, tapioca starch, potato starch, waxy corn starch, etc.). It retains the advantages of the natural source of starch while significantly improving the water solubility, stability, and processing performance of the original starch by introducing hydroxypropyl groups.
