Product Description

What is HPMC/Hemc?

Hydroxypropyl Methylcellulose (HPMC) is a nonionic cellulose alkyl hydroxyalkyl mixed ether. It's made from cellulose through alkalization, etherification, neutralization, and washing.

Hydroxypropyl Methyl Cellulose Ether

As a nonionic cellulose mixed ether with excellent performance, HPMC has good dispersing, emulsifying, thickening, bonding, water retention, and glue retention properties – just like other cellulose ethers (CMC, MC, HEC, MHEC, HEMC, HBMC). It dissolves in water and also dissolves in ethanol and acetone below 70°C. You can use it widely as a thickener and adhesive. Thanks to its thickening, dispersing, emulsifying, and film‑forming abilities, it's used in petrochemicals, building materials, ceramics, textiles, daily chemicals, synthetic resins, coatings, electronics, and other industrial fields.

HPMC in Cement Mortar

HPMC plays many roles in construction materials. You can add it to masonry mortar, plastering mortar, stucco, and plastering paste. Even a small amount makes a big difference. In cement and gypsum plasters, HPMC's water retention gives you higher bond strength and better hardness after curing.

Good water retention lets cement hydrate fully. That means stronger bonds, better tensile and shear strength in hardened mortar, and easier handling. Construction goes smoother and faster.

When you're working with cement mortar, you need good water retention. Bricks and walls soak up water quickly, and mortar usually has a lot of sand. Without enough water retention, bricks pull water out too fast. The mortar loses water in spots, and the cement doesn't hydrate fully. Mortar made with sand, lime, and cement has low natural bond strength. But add cellulose ether, and bond strength goes way up – even under heavy loads or sideways stress.

FAQ

What are your prices?
Prices change based on availability and market conditions. Contact us for an up‑to‑date price list.

Can you provide documentation?
Yes. We can provide most documents, including certificates of analysis, conformity certificates, and other export papers. We also offer solid after‑sales service.

How is shipping cost calculated?
It depends on the shipping method. Express is fastest but most expensive. Sea freight works best for large volumes. We need quantity, weight, and method to give you an exact cost. Contact our sales team.
