Product Overview

HPMC is a non-ionic cellulose ether derived from natural polymers like cotton through chemical modification. It is available in two main types: hot-dissolving and instant-dissolving. The hot-dissolving variant is ideal for dry mixtures such as wall putty and mortar, while the instant-dissolving type is suited for liquid products like adhesives and coatings.

Key Properties and Advantages

• Excellent Thickening Effect: HPMC enhances viscosity in surfactant systems, improving product consistency.
• Superior Water Retention: Prevents rapid drying and cracking in applications like mortars and coatings.
• Enhanced Bonding: Ensures strong adhesion in construction materials and adhesives.
• Thermal Stability: Maintains performance under varying temperature conditions.

Applications Across Industries

1. Construction

HPMC is critical in gypsum and mortar formulations. It improves workability, water retention, and mechanical strength. For example, in exterior wall insulation mortar, HPMC enhances adhesion to surfaces and reduces micro-cracks (HPMC for Exterior Wall insulation Mortar).

2. Pharmaceuticals

As a medical excipient, HPMC acts as a binder, disintegrant, and controlled-release agent in tablets and capsules. Its non-toxic nature ensures safety for patient use.

3. Food Industry

HPMC functions as a thickener and fat replacer in food products, contributing to texture and stability without compromising nutritional value.

4. Cosmetics

In skincare, HPMC forms a smooth, non-greasy film on the skin, enhancing moisture retention and product spreadability (HPMC Skincare).

HPMC vs. HEC: Key Differences

While both Hydroxyethylcellulose (HEC) and HPMC are cellulose derivatives, their properties diverge:

• HEC: Excels in film formation and clarity, ideal for skincare and pharmaceuticals.
• HPMC: Offers superior water retention and thermal stability, preferred in construction and adhesives.

Manufacturing Process

1. Raw Material Preparation: High-quality cellulose, propylene oxide, and catalysts are selected and mixed according to precise formulas.
2. Reaction: The mixture undergoes etherification under controlled temperature and pressure to form HPMC.
3. Refining: Impurities are removed via centrifugation and washing, followed by drying to achieve the final product.
4. Packaging: HPMC is packed in multi-layer paper bags (25 kg net weight) for safe storage and transport.

Storage and Handling

HPMC should be stored in a cool, dry place away from sunlight. Unopened packaging maintains quality for years, while opened container111s require protection from humidity. For safety guidelines, refer to the MSDS.
