Tha HPMC a’ frithealadh mar thiughadair, ceanglaiche, foirmean film, agus àidseant gleidhidh uisge. In building and construction materials like tile adhesives and makes, it assists keep water, a’ leasachadh comas obrach, and improves bond. Ann an clàran agus pilichean, it regulates medication release and works as a binder. Its thermal gelation property permits it to create gels when heated, which is useful in specific formulations.

Technical Grades

Different qualities of HPMC are available based on methoxyl and hydroxypropyl substitution levels. Tha raointean tiugh cumanta a’ toirt a-steach 4,000 mPa·s, 15,000 mPa·s, 40,000 mPa·s, agus timcheall air 100,000 mPa·s(air a thomhas aig 2% fòcas, 20 °C). Each grade meets rigorous top quality criteria for purity and performance.

Sàbhailteachd agus làimhseachadh

HPMC is safe and typically acknowledged as secure (GRAS) for usage in food and pharmaceutical applications. Bùth ann an stoidhle iongantach, àite gu tur tioram fada bho taiseachd. Usage basic commercial hygiene methods when handling the powder to prevent dust inhalation. Cùm soithichean dùinte gu daingeann nuair nach eilear gan cleachdadh.
