I-Viscosity (2% ikhambi ku 20 °C): 50– 100,000 mPa · s (ihluke ngekhwalithi).
pH (2% isevisi): 4.0– 8.0.
Izinga lokushisa le-gel: 50 °C– 90 °C( depends on replacement degrees).

Izicelo Ezivamile

Ekwakheni imikhiqizo, HPMC enhances attachment, ukugcinwa kwamanzi, and droop resistance in ceramic tile adhesives, inikeza, kanye nama-self-leveling compounds. In the pharmaceutical industry, it is utilized in tablets for managed drug launch and as an eye lube in fabricated tears. Food producers utilize it as a thickener or emulsifier (Inombolo ye-E464). It likewise appears in cosmetics, amapende, and agricultural products as a result of its security and compatibility.

Indawo yokugcina kanye Nokusingatha

Gcina i-HPMC ngendlela emangalisayo, indawo eyomile ngokuphelele kude nomswakama. Maintain containers firmly closed. Usage conventional industrial hygiene methods when dealing with. Gwema ukungcola okuphefumulayo. Use gloves and shatterproof glass if required. The service life is normally 24 izinyanga uma zigcinwe ngendlela efanele.

Izicelo zeHydroxypropyl Methylcellulose (I-HPMC)

Building Products

I-HPMC plays a crucial function in dry-mix mortars like floor tile adhesives, amapulasi, nezinto ezizilinganisa. It enhances workability by providing the mix a smooth appearance. Water retention is an additional huge benefit– it maintains wetness in the mix longer so concrete can totally moisten. This brings about stronger bonds and fewer cracks. HPMC additionally quits products from sagging on upright surface areas.

Ezemithi

Emithini, I-HPMC is made use of as a binder, finish representative, noma isithako esikhishwe okulawulwayo. Tablet finishes made with HPMC liquify at the right time in the digestion system. This aids deliver medicines precisely where they are required. It is secure, iphephile, and authorized by significant health companies worldwide.

Imakethe Yokudla

I-HPMC imisebenzi njenge-thickener, i-emulsifier, and stabilizer in many foods. You’ll discover it in sauces, izinketho zobisi, and gluten-free baked goods. It provides items a better mouthfeel and maintains components blended uniformly. Due to the fact that it’s plant-based and stable under warmth, it fits well in contemporary food handling.

Personal Treatment and Cosmetics

Ama-shampoos, amakhilimu, and tooth pastes frequently contain I-HPMC. It adds body to fluids and assists put on hold fragments like exfoliants or pigments. The outcome is a regular product that feels smooth on skin or hair. It additionally increases foam top quality in cleansers without aggravating the skin.

Amapende nama-Coatings

I-HPMC enhances paint performance by managing thickness and avoiding pigment settling. It makes application much easier– whether by brush, roller, noma fafaza. Ngemva kokumisa, films stay uniform and withstand splitting. This makes HPMC a dependable choice for both interior and exterior paints.
