Hydroxypropyl Methyl Cellulose (HPMC)– Spesifikasi Item

Summary

Hidroksipropil metil selulosa (HPMC) is a white to off-white, bubuk tanpa bau. It liquifies quickly in cool water and develops a clear, pilihan kandel. This product is widely utilized in building, obat-obatan, panganan, and personal treatment due to its superb thickening, ngiket, 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) ing 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, lan HPMC 200000.

Lower-viscosity grades like HPMC 400 lan 4000 work well as binders or in applications needing fast dissolution. Tool grades such as HPMC 6000 kanggo 60000 deal balanced performance for ceramic tile adhesives, plesteran, and coatings. High-viscosity types like HPMC 80000 kanggo 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 lan 90 ° C, depending upon the methoxyl and hydroxypropyl web content.

Ruang panyimpenan lan Penanganan

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.

Aplikasi saka Hydroxypropyl Methyl Cellulose (HPMC)

Construction and Building Materials

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

Obat-obatan

Ing obat, HPMC 4000 lan 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, ora beracun, and satisfy rigorous high quality requirements. Some high-viscosity variations also work as eye decrease thickeners to alleviate dryness.

Industri Pangan

Food-grade HPMC, umume HPMC 4000 utawa HPMC 150000, fungsi minangka thickener, penstabil, 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.

Paint lan Coatings

Paint makers make use of HPMC 80000 lan 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. Ing lotion, it gives a smooth feel. Ing lusters Keramik, 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, utawa 100000?

HPMC singkatan saka hydroxypropyl methyl cellulose. It is a common additive used in construction, panganan, and pharmaceuticals. The numbers (400, 4000, 6000, lsp.) 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?

Kanggo adhesives kothak, medium to high viscosity grades work best. Choose HPMC 40000, 60000, utawa 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?

ya wis. HPMC 400 has very low viscosity and dissolves quickly in cold water. It is often used as a thickener or stabilizer in sauces, alternatif susu, lan barang panggang. 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% kanggo 0.4% of total dry weight—and mix thoroughly with other ingredients.

How do I store HPMC powder safely?

Tansah HPMC ing kelangan, panggonan garing. Tutup tas kanthi kenceng sawise mbukak. Moisture makes it clump or lose performance. Ngindhari sinar srengenge langsung lan kelembapan sing dhuwur. Properly stored, iku tetep efektif kanggo nganti 12 wulan.
