Product Introduction
Our construction‑grade Hydroxypropyl Methyl Cellulose (HPMC) is a high‑purity, odour‑free white powder engineered for dry‑mix mortar applications, CAS No. 9004‑65‑3.
Produced under strict standardized production control, this functional powder delivers outstanding water retention, thickening and workability‑improving performance for tile adhesives, wall plasters, cement mortars and gypsum‑based products. Every batch undergoes full laboratory inspection to ensure stable physicochemical properties, low‑level impurities and reliable lot‑to‑lot consistency.
Upon request, we provide complete compliance documents including batch‑specific COA, MSDS and technical data sheets, supporting customs clearance as well as customers’ formula R&D and testing. Widely recognised in global building‑material markets, our HPMC earns long‑term trust from dry‑mortar producers and construction‑chemical distributors worldwide.

Core Physical & Chemical Indicators

Appearance: Uniform white or off‑white, odorless fine powder

pH Range: 4.0‑8.0. Mild property, non‑corrosive to cement and gypsum‑based substrates

Loss on Drying: ≤5.0%

Residue on Ignition: Low ash content to guarantee stable performance during long‑term mortar curing

Heavy Metals & Arsenic: Strictly controlled within safety limits, compliant with global building chemical safety standards

Viscosity Options: Multiple adjustable viscosity grades available for different construction formula requirements

Storage Stability: Quality remains stable in cool and dry conditions. Shelf life up to 24 months under properly sealed storage

Standard Packaging: 25kg kraft paper bag with inner PE moisture‑proof liner, leak‑proof and dust‑proof, suitable for ocean freight

Unique Performance Advantages for Construction Projects

Unique Performance Advantages for Construction Projects

• Excellent Water Retention Locks mortar moisture, prevents fast water loss under hot, dry or sunny conditions. Avoids putty cracking, hollowing and peeling, and extends workable time.
• Anti‑Slip & Strong Adhesion Prevents large ceramic and marble tiles from slipping on vertical walls. Boosts mortar bonding strength on concrete and brick substrates.
• Good Construction Lubricity Offers fine plasticity and trowel‑ability. Reduces plastering resistance and saves labor for on‑site work.
• Stable Dispersion Mixes evenly with dry cement powder. No fish‑eye agglomerates after water addition for consistent mortar texture.
• Safe & Low‑Hazard No toxic volatiles and no harmful fumes during use per MSDS. Only normal ventilation required, no special transport restrictions.
