1. Product Overview
InnoNew Material is a professional manufacturer specializing in construction chemical additives, our Hydroxypropyl Methyl Cellulose (HPMC) is high-purity cellulose ether refined from natural cotton linter via alkalization, etherification, washing and drying processes. It is white fine flowing powder, non-toxic and eco-friendly, with outstanding water retention, thickening, anti-sagging, lubrication and workability improvement functions, serving as core additive for dry-mix building materials globally.

3. Core Superior Performance & Innovation Points
Ultra Stable Batch ConsistencyOur closed automated production line realizes precise etherification degree control; viscosity fluctuation range is controlled within ±5%, effectively avoiding construction sagging, slow setting and insufficient bonding caused by unstable raw material quality for customers.
High Water Retention TechnologyOptimized molecular structure design keeps water retention rate ≥98%; greatly extends open time of tile adhesive, prevents rapid water loss on porous base wall, reduces hollowing and tile falling rate.
Dual Fast/Slow Dissolving OptionsStandard instant-soluble type disperses rapidly under stirring without agglomeration; delayed-soluble type avoids powder clumping in automatic dry mortar batching systems, perfectly matching automatic mixing production lines.
Low Ash & Low Impurity FormulaControlled ash content ≤3.5%, no insoluble foreign matter, will not form pinholes and rough surface on putty and mortar finished surfaces, improving construction smoothness.
4. Wide Application Range
✅ Tile adhesive, large format tile glue, marble adhesive
✅ Interior & exterior wall putty, skim coat
✅ Dry mix masonry mortar, rendering mortar
✅ Self-leveling cement mortar, floor grout

FAQ
Q1: What is the recommended addition dosage of your HPMC?
A: Conventional dosage ranges from 0.02%–0.5% of total dry raw materials; tile adhesive uses 0.2%–0.35%, wall putty uses 0.1%–0.25%. Our technical team can provide targeted formulation suggestions according to your local raw materials and construction environment.
Q2: Can you customize HPMC gel temperature and dissolution speed?
A: Yes, InnoNew Material supports customized gel temperature (55℃~85℃), instant/slow dissolving type, mesh size and viscosity adjustment to match high-temperature construction areas and automatic mortar production lines.
Q3: How to guarantee batch viscosity stability of HPMC?
A: We adopt full-automatic closed reaction production equipment, each batch undergoes three viscosity tests before delivery, viscosity tolerance controlled within ±5%; we can provide free sample testing before bulk order cooperation.
Q4: What payment terms do you accept for HPMC bulk orders?
A: We support T/T, L/C at sight, D/P, Western Union and other flexible payment methods, suitable for long-term cooperative distributors and mortar factories.
Q5: Do you provide technical support for mortar formula optimization?
A: Yes, our professional construction chemical engineers offer remote formula guidance free of charge; for large long-term partners, overseas on-site technical service is negotiable.
