Characteristics and advantages of hydroxypropyl methyl cellulose HPMC 400 4000 6000 40000 60000 80000 100000 150000 200000

Excellent water solubility: It can be quickly dissolved in cold water to form a clear and stable solution.

Efficient thickening and water retention ability: Increase the viscosity of the material, effectively reduce water evaporation, and improve work efficiency.

Good stability: It has good stability to acids, alkalis, and salts, and is suitable for a wide range of pH values.

Film-forming and protective effects: After drying, it forms a tough and transparent film to protect the substrate and prevent water penetration and evaporation.

Non-toxic and non-irritating: It has good biocompatibility and is suitable for the fields of medicine and food.

Adjustability: By changing the degree of substitution and molecular weight, its performance can be adjusted to meet different application requirements.

Hydroxypropyl Methyl Cellulose (HPMC)– Item Specs

Summary

Hydroxypropyl methyl cellulose (HPMC) is a white to off-white, odor-free powder. It liquifies quickly in cool water and develops a clear, thick option. This product is widely utilized in building, drugs, food, and personal treatment due to its superb thickening, binding, and film-forming residential or commercial properties.

Viscosity Grades

HPMC is available in several thickness qualities. Each quality is called after its approximate viscosity in millipascal-seconds (mPa · s) at 2% focus and 20 ° C. Common grades consist of:
HPMC 400, HPMC 4000, HPMC 6000, HPMC 40000, HPMC 60000, HPMC 80000, HPMC 100000, HPMC 150000, and HPMC 200000.

Lower-viscosity grades like HPMC 400 and 4000 work well as binders or in applications needing fast dissolution. Tool grades such as HPMC 6000 to 60000 deal balanced performance for ceramic tile adhesives, plasters, and coatings. High-viscosity types like HPMC 80000 to 200000 offer strong water retention and are suitable for self-leveling substances and high-performance mortars.

Trick Qualities

All HPMC grades are non-ionic and steady throughout a wide pH array (3– 11). They stand up to microbial attack and do not interact with many salts or surfactants. The gel temperature level generally falls in between 50 ° C and 90 ° C, depending upon the methoxyl and hydroxypropyl web content.

Storage space and Handling

Store HPMC in an awesome, completely dry place away from dampness. Keep containers firmly closed. Avoid long term direct exposure to humid air to avoid clumping. Usage standard industrial health methods when handling the powder to limit dirt inhalation.

Applications of Hydroxypropyl Methyl Cellulose (HPMC)

Construction and Building Materials

HPMC is extensively made use of in cement-based items like tile adhesives, provides, and self-leveling compounds. Grades such as HPMC 400 and HPMC 6000 enhance workability and water retention. This aids seal moisturize appropriately and minimizes fracturing. Higher-viscosity kinds like HPMC 100000 or HPMC 200000 include thickness and prevent drooping on vertical surfaces.

Drugs

In medication, HPMC 4000 and HPMC 6000 act as binders or film-coating agents for tablet computers. They manage just how fast a medication dissolves in the body. These grades are safe, non-toxic, and satisfy rigorous high quality requirements. Some high-viscosity variations also work as eye decrease thickeners to alleviate dryness.

Food Industry

Food-grade HPMC, commonly HPMC 4000 or HPMC 150000, functions as a thickener, stabilizer, or emulsifier. It maintains sauces smooth, stops ice crystals in frozen desserts, and boosts texture in gluten-free baked goods. It is approved for usage in lots of countries and identified as E464.

Paints and Coatings

Paint makers make use of HPMC 80000 and HPMC 100000 to boost viscosity and stop pigment settling. These grades assist repaint spread equally and stick better to walls. They likewise decrease splatter during application and boost storage space security.

Various other Uses

HPMC appears in cosmetics, ceramics, and agricultural chemicals too. In lotions, it gives a smooth feel. In ceramic lusters, it holds bits with each other prior to shooting. Low-viscosity grades like HPMC 400 match liquid systems, while ultra-high types like HPMC 200000 support gels or pastes. Each quality provides specific performance based upon its molecular weight and alternative level.

Frequently Asked Questions About HPMC Grades

What is HPMC and why are there so many numbers like 400, 4000, or 100000?

HPMC stands for hydroxypropyl methyl cellulose. It is a common additive used in construction, food, and pharmaceuticals. The numbers (400, 4000, 6000, etc.) show the viscosity of the product in millipascal-seconds (mPa·s). A low number like 400 means thin and fast-dissolving. A high number like 200000 means thick and slow-moving when mixed with water.

Which HPMC grade should I use for tile adhesives?

For tile adhesives, medium to high viscosity grades work best. Choose HPMC 40000, 60000, or 80000. These help keep the mix sticky and prevent tiles from sliding. They also improve water retention so cement can cure properly.

Can I use HPMC 400 in food products?

Yes. HPMC 400 has very low viscosity and dissolves quickly in cold water. It is often used as a thickener or stabilizer in sauces, dairy alternatives, and baked goods. Always confirm the product meets food-grade safety standards before use.

Why does my plaster crack when I use HPMC 150000?

HPMC 150000 is very thick. If you add too much, it can trap air or reduce workability. This may cause drying cracks. Use the right dosage—usually 0.2% to 0.4% of total dry weight—and mix thoroughly with other ingredients.

How do I store HPMC powder safely?

Keep HPMC in a cool, dry place. Seal the bag tightly after opening. Moisture makes it clump or lose performance. Avoid direct sunlight and high humidity. Properly stored, it stays effective for up to 12 months.
