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, tshuaj, khoom noj khoom haus, and personal treatment due to its superb thickening, khi, 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) ntawm 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, thiab HPMC 200000.

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

Cov yam ntxwv tseem ceeb

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 thiab 90 ° C, depending upon the methoxyl and hydroxypropyl web content.

Cia thiab tuav

Store HPMC in an awesome, qhov chaw qhuav kiag li kom deb ntawm ntub dej. 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, muab, thiab nws tus kheej theem tebchaw. Grades such as HPMC 400 thiab 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.

Tshuaj

In medication, HPMC 4000 thiab 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.

Kev Lag Luam Khoom Noj Khoom Haus

Food-grade HPMC, feem ntau 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.

Cov xim thiab txheej txheej

Paint makers make use of HPMC 80000 thiab 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, h, and agricultural chemicals too. Hauv cov tshuaj pleev kis, 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 sawv rau hydroxypropyl methyl cellulose. It is a common additive used in construction, khoom noj khoom haus, 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?

Rau cov nplaum pobzeb, 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?

Yog. HPMC 400 has very low viscosity and dissolves quickly in cold water. It is often used as a thickener or stabilizer in sauces, lwm txoj hauv kev mis nyuj, 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. Yog tias koj ntxiv ntau dhau, it can trap air or reduce workability. This may cause drying cracks. Use the right dosage—usually 0.2% rau 0.4% of total dry weight—and mix thoroughly with other ingredients.

How do I store HPMC powder safely?

Khaws HPMC hauv qhov txias, qhov chaw qhuav. Kaw lub hnab nruj tom qab qhib. Moisture makes it clump or lose performance. Zam lub hnub ci ncaj qha thiab av noo siab. Properly stored, Nws nyob twj ywm kom txog 12 hlis.
