Hidroxipropil metil celulosa (HPMC)– Especificacións do produto

Visión xeral

Hidroxipropil metil celulosa (HPMC) is a white or beige powder. It dissolves in cold water to form a clear, opción viscosa. HPMC is extensively used in building, produtos farmacéuticos, comida, and cosmetics due to its excellent thickening, encadernación, formador de película, and water-retention buildings.

Graos de viscosidade

HPMC is available in several viscosity grades. Each grade is named by its approximate thickness in millipascal-seconds (mPa · s) á a 2% concentración en auga a 20 °C. Common qualities consist of:
HPMC 400, HPMC 4000, HPMC 6000, HPMC 40000, HPMC 60000, HPMC 80000, HPMC 100000, HPMC 150000, e HPMC 200000.

Lower-viscosity qualities like HPMC 400 e 4000 are excellent for applications needing simple circulation and quick dissolution. Tool qualities such as HPMC 6000 a 60000 offer well balanced performance for floor tile adhesives and plasters. High-viscosity types like HPMC 80000 a través 200000 supply strong water retention and enlarging, suitable for self-leveling compounds and specialized mortars.

Versatile Grades for Diverse Demands

Hidroxipropil metil celulosa, ou HPMC, can be found in many viscosity qualities– como 400, 4000, 6000, 40000, 60000, 80000, 100000, 150000, e 200000. Each grade serves a specific purpose based upon its thickness and efficiency in water.

Low-viscosity qualities like HPMC 400 and HPMC 4000 mix easily into liquids. They function well in floor tile adhesives, compostos autonivelantes, e morteiros en seco. These grades help regulate water retention so seal collections appropriately.

Medium grades such as HPMC 6000 and HPMC 40000 are common in outside insulation systems and plaster. They offer great workability and quit drooping on vertical surface areas. Home builders depend on them for smooth application and strong attachment.

High-viscosity types– consisting of HPMC 60000 , 80000 , 100000 , 150000 , e 200000 — are thick and steady. They are utilized where long open time and high water retention issue the majority of. Instances consist of thick-bed renders, servizo de reparación de morteiros, and specialized grouts. These grades keep the mix wet much longer, which helps healing in hot or dry conditions.

Efficiency You Can Trust Fund

HPMC boosts consistency across all construction products. It avoids separation of ingredients and makes mixing less complicated. The item likewise minimizes dust during handling and boosts pumpability.

In addition to construction, some HPMC qualities sustain pharmaceutical and food usages. Yet in structure applications, the focus stays on stamina, traballabilidade, and dependability.

Different projects require various thickness. Selecting the appropriate HPMC grade makes sure much better results– whether you’re laying floor tiles, finish walls, or fixing concrete. Constantly match the quality to your mix style and job conditions.

Frequently Asked Questions About HPMC Grades

What is HPMC and why are there so many grades?

HPMC significa hidroxipropilmetilcelulosa. É un polímero soluble en auga feito a partir de celulosa vexetal. Different grades—like 400, 4000, 6000, up to 200000—refer to viscosity levels. Higher numbers mean thicker solutions when mixed with water. Each grade suits specific uses based on how thick or thin the final product needs to be.

Which HPMC grade works best in construction materials?

Grades such as 40000, 60000, e 100000 are common in tile adhesives, renderiza, e emplastos. They give good workability, retención de auga, e tempo aberto. Lower grades like 400 ou 6000 are too thin for these jobs. High-viscosity HPMC helps keep water in the mix so cement can cure properly.

Can I use high-viscosity HPMC in food or pharmaceuticals?

Si, but only if it meets food-grade or pharma-grade standards. Viscosity matters less than purity here. Grades like 400 ou 4000 are often used in tablets or sauces because they dissolve quickly and feel smooth. Always check the product’s certification before using it in consumables.

How does viscosity affect performance?

Viscosity controls thickness and flow. HPMC de baixa viscosidade (p.ex., 400–6000) spreads easily and mixes fast. High-viscosity types (p.ex., 150000–200000) create gels that hold shape and slow down water loss. Pick the right viscosity based on whether you need fluidity or stability.

HPMC é seguro de manexar?

HPMC é non tóxico e biodegradable. It does not irritate skin under normal use. Aínda así, wear gloves and a mask when handling fine powders to avoid breathing dust. Store it in a dry place—it absorbs moisture from the air and may clump.
