HPMC Production Equipment Highlights
Advanced Etherification Reactors with DCS Control
Keyong’s production facility features multiple stainless-steel etherification reactors equipped with Distributed Control System (DCS) monitoring. This allows for precise control over reaction temperature, pressure, and duration—critical for achieving consistent viscosity and substitution levels in HPMC
Integrated Production Workflow (Crushing → Etherification → Refining → Mixing → Packaging)
Our plant follows an efficient, integrated workflow that includes raw material crushing, alkalization, etherification, powder refining, blending, and packaging. This streamlined process ensures uniform quality and high production throughput.
High-Precision Downstream Equipment: Filtration, Drying & Milling
After the chemical reaction, our HPMC slurry undergoes filtration (e.g., rotary pressure filters), controlled drying, and fine milling to produce homogeneous, powdery HPMC with minimal impurities—ideal for construction-grade and specialty applications
Keyong Hydroxypropyl Methylcellulose key application
Keyong HPMC excels as a thickener (enhancing viscosity), emulsifier/stabilizer, and film-forming agent across diverse sectors:
- Construction: improves cohesion, water retention, and workability in wall putty, mortar, and tile adhesives;
- Coatings & Paints: controls flow, prevents sagging, enhances stability;
- Daily Chemicals & Oil Drilling: supports texture and suspension in personal care products and stabilizes drilling fluids.
FAQs
How to choose the right HPMC grade for my application?
Refer to our Product Series section—select Standard for general use or Premium for high-performance needs. Our R&D team can guide precise selection.
Can I test the product before placing a large order?
Yes, we offer sample kits (200–400 g) for you to evaluate in your specific formulation.
Do you offer custom packaging or private labeling?
Absolutely—OEM packaging and labeling options are available per client request.
What are typical dosing guidelines across different applications?
Use approximately 0.4–0.6% for wall putty; 0.3–0.5% for tile adhesive; 0.8–1.2% for self-leveling compounds; exact ratios may vary—consult our technical team.
