</div>

<p style="color:#444444;font-size:16px;line-height:1.8;margin:0 0 15px 0;">Hydroxypropyl methyl cellulose ether is a non-ionic, water-soluble polymer produced by treating refined natural cellulose with controlled etherification, grafting methyl and hydroxypropyl groups onto the cellulose backbone. In our production, this yields a methoxyl content of 19–30% and a hydroxypropyl content of 4–12% — the substitution window trusted across the cellulose ether industry.</p>

<p style="color:#444444;font-size:16px;line-height:1.8;margin:0 0 15px 0;">Because the polymer carries no electrical charge, hydroxypropyl methyl cellulose ether dissolves into a neutral solution of pH 6.0–7.0 and coexists with salts, surfactants, cements and active ingredients without unwanted reactions. It thickens efficiently, retains water at a rate of 90% or higher, and gels reversibly between 65–75°C before returning to full solubility on cooling.</p>

<p style="color:#444444;font-size:16px;line-height:1.8;margin:0;">We supply hydroxypropyl methyl cellulose ether as a white or off-white powder with a free-flowing bulk density of 350–450 kg/m³, spanning 300–200,000 mPa·s in viscosity. Every lot leaves the plant with a certificate of analysis, so your incoming inspection starts from verified data.</p>

</div>

<h3 style="color:#1d5c96;font-size:17px;font-weight:700;margin:0 0 8px 0;">What is hydroxypropyl methyl cellulose ether?</h3>

<p style="color:#555555;font-size:15px;line-height:1.7;margin:0 0 20px 0;">It is a non-ionic, water-soluble cellulose ether made by grafting methyl groups (19–30% methoxyl content) and hydroxypropyl groups (4–12% hydroxypropyl content) onto natural cellulose. The result is a white or off-white powder that thickens, retains water and gels reversibly at 65–75°C.</p>

<h3 style="color:#1d5c96;font-size:17px;font-weight:700;margin:0 0 8px 0;">How does hydroxypropyl methyl cellulose ether differ from other cellulose ethers?</h3>

<p style="color:#555555;font-size:15px;line-height:1.7;margin:0 0 20px 0;">Its dual substitution of methyl and hydroxypropyl groups delivers the best overall balance of solubility, thermal gelation and water retention — which is why it is the most widely specified cellulose ether in both construction and pharmaceutical formulation.</p>

<h3 style="color:#1d5c96;font-size:17px;font-weight:700;margin:0 0 8px 0;">Which viscosity grade do I need?</h3>

<p style="color:#555555;font-size:15px;line-height:1.7;margin:0;">Our hydroxypropyl methyl cellulose ether spans 300–200,000 mPa·s. Lower viscosities suit self-leveling systems and sprays, mid-range grades serve tile adhesives and renders, and high-viscosity grades maximize water retention where workability is critical. Our lab recommends the exact grade for your formulation.</p>

</div>

<h3 style="color:#1d5c96;font-size:17px;font-weight:700;margin:0 0 8px 0;">What is your minimum order quantity?</h3>

<p style="color:#555555;font-size:15px;line-height:1.7;margin:0 0 20px 0;">MOQ is 500 kg for standard grades. Trial quantities of 25 kg can be arranged for qualification testing, and free samples are available before any commitment.</p>

<h3 style="color:#1d5c96;font-size:17px;font-weight:700;margin:0 0 8px 0;">How should hydroxypropyl methyl cellulose ether be stored?</h3>

<p style="color:#555555;font-size:15px;line-height:1.7;margin:0 0 20px 0;">Store in the original sealed bag in a dry, ventilated area. Properly stored, the product keeps its specifications for 24 months without measurable viscosity loss.</p>

<h3 style="color:#1d5c96;font-size:17px;font-weight:700;margin:0 0 8px 0;">Do you provide documentation with each order?</h3>

<p style="color:#555555;font-size:15px;line-height:1.7;margin:0;">Yes. Every hydroxypropyl methyl cellulose ether shipment includes a full certificate of analysis covering appearance, viscosity, substitution contents, pH, bulk density, water retention and gelation temperature.</p>
