HPMC 2420A/ 2410A– Augstas tīrības pakāpes hidroksipropilmetilceluloze

Preču apskats

Our HPMC 2420A and 2410A are premium-grade hydroxypropyl methyl cellulose products. They fulfill stringent top quality requirements for commercial and construction usage. Both grades carry CAS number 9004-65-3 and use dependable efficiency in demanding applications.

Triku prasības

These HPMC grades feature a low substitution account, which supports superb water retention and workability. The methoxy content varies from 19% uz 24% , while the hydroxypropoxy material falls between 4% un 12% . Viscosity is measured at 20 ° C in a 2% šķidrs šķīdums:
– HPMC 2420A : 18,000– 22,000 mPa · s.- HPMC 2410A : 8,000– 12,000 mPa · s.

Both products look like white to off-white free-flowing powders. They liquify quickly in cold water but do not liquify in hot water over gelation temperature level (typically 50– 70 °C ). pH a 2% remedy stays within 6.0– 8.0 , ensuring compatibility with common building products.

Efektivitātes priekšrocības

Ūdens aizture is strong, which aids cement-based blends stay practical much longer. This decreases cracking and enhances bond. Darbspēja remains constant even under varying temperature levels. The item also provides excellent film-forming ability and serves as a reliable thickener. It stands up to microbial deterioration and preserves security in storage space when kept completely dry.

Tipiski pielietojumi

These HPMC grades are commonly used in:.
– Grīdas flīžu līmes.
– Ārējās izolācijas gala sistēmas (EIFS).
– Pašlīmeņojošas vielas.
– Apmetumus un nodrošina.
– Ģipša izstrādājumi.

Produced under regulated conditions, each batch undertakes strenuous testing to make certain harmony and compliance with global requirements. Iepērcieties pārsteidzošā veikalā, completely dry location away from dampness to protect efficiency.

Applications of Factory-Grade HPMC (Hidroksipropilmetilceluloze)– Qualities 2420A & 2410A

Secret Utilizes in Building and Structure Products

Factory-grade HPMC with CAS number 9004-65-3 is extensively utilized in building. Grades 2420A and 2410A use strong water retention and workability. These homes make them optimal for tile adhesives, apmetumi uz cementa bāzes, un pašizlīdzinošie maisījumi. The HPMC assists keep water in the mix longer. This offers workers more time to apply and smooth the material before it establishes.

Function in Dry-Mix Mortars

Sausā maisījuma javās, HPMC kalpo kā biezinātājs un stabilizators. It avoids components from dividing during storage space or mixing. Low alternative grades like 2410A improve open time and decrease droop on upright surfaces. This is very important for plaster and skim layer applications where smooth finishes are needed.

Benefits in Gypsum-Based Products

HPMC additionally works well with gypsum plasters and joint compounds. It regulates water release so the plaster establishes equally. This reduces cracking and improves surface strength. Grade 2420A , with somewhat greater viscosity, gives better movie formation and bond in these systems.

Performance in Outside Insulation Equipments

For external thermal insulation composite systems (ĒTIKAS), HPMC enhances versatility and cohesion. It helps the base coat stick strongly to insulation boards while withstanding climate tension. Both 2410A and 2420A support consistent texture and simple troweling– key for quick, clean installment.

Why Select These Grades?

These HPMC qualities are made for commercial use. They dissolve conveniently in cool water and remain steady under regular job-site conditions. Their reduced gel temperature guarantees efficiency also in warmer climates. Manufacturers rely upon them for predictable outcomes set after set.
