With the advancement in chemical synthesis and application technologies, **hydroxypropyl methyl cellulose ether** continues to replace traditional cellulose derivatives in various fields, offering green, high-performance alternatives.
- Q1: What is the molecular structure of hydroxypropyl methyl cellulose ether?
- A1: It is a non-ionic cellulose ether, derived from alkali cellulose and reacted with methyl chloride and propylene oxide. The resulting structure features hydroxypropyl and methoxyl groups providing solubility and gelation functionality (More Info).
- Q2: What are the available viscosity grades?
- A2: Viscosity options span from 400 to 200,000 mPa.s (2% solution, 20°C). Applications often dictate the appropriate grade; construction-grade ranges are widely in the 50,000–150,000 mPa.s window.
- Q3: What are the storage and shelf-life recommendations?
- A3: Store in a cool, dry environment. The material is stable for over 24 months in sealed packaging, with minimal moisture uptake or functional loss if protected from direct sunlight and humidity.
- Q4: How can compatibility be evaluated in building materials?
- A4: Compatibility with cement, gypsum, and lime is crucial. Laboratory tests involve setting time, flexural/compressive strength, adhesion, and shrinkage measurements to tailor **hydroxypropyl methyl cellulose ether** performance.
- Q5: What are the main installation standards for use in drymix mortars?
- A5: International standards include EN 998 (European Standard for Thin Layer Mortars for Masonry), ASTM C91 (United States Portland Cement Based Plaster), ensuring optimized HPMC content and mixture homogeneity.
- Q6: Does HPMC affect mortar open time and sag resistance?
- A6: Yes. The unique molecular modification of **hydroxypropyl methyl cellulose ether** improves water retention, extends open time and enhances anti-sagging, crucial for tile adhesives and putties.
- Q7: Are custom formulations or private labeling available?
- A7: Pengze Technology (Shijiazhuang) Co., Ltd. provides OEM/ODM customization to meet unique viscosity, gelation, and regulatory requirements for global clients.
