Cellulose is abundant in nature, primarily found in the cell walls of green plants, notably in cotton, wood, flax, and hemp. Certain vegetables like broccoli and Brussels sprouts, as well as fruits and grains, also contain cellulose in smaller amounts. This polysaccharide is so prevalent that it is estimated that cellulose is the most abundant organic polymer on Earth, far surpassing other natural materials in terms of quantity.

Além disso, a Ashland desenvolve HEC com diferentes graus de viscosidade e tipos de viscosidade, permitindo que os formuladores selecionem a versão que melhor atende às suas necessidades específicas. Esta flexibilidade é um grande diferencial para indústrias que buscam inovação e eficácia em seus produtos.


Οι υψηλές συγκεντρώσεις υποκαταστάτη (HPMC) είναι γνωστές για τη χρήση τους σε διάφορες βιομηχανίες, ιδίως στη φαρμακοβιομηχανία και τη βιομηχανία τροφίμων. Η υδροξυπροπυλομεθυλκυτταρίνη (HPMC) είναι ένα συνθετικό πολυμερές που παράγεται από φυσική κυτταρίνη και έχει αναδειχθεί ως ένα από τα πιο ευέλικτα πρόσθετα. Η υψηλή ιξώδης HPMC προσφέρει μοναδικά χαρακτηριστικά που την καθιστούν ιδανική για πολλές εφαρμογές.

4. Stability and Performance The stability of HPMC can also be affected by its molecular weight. Generally, HPMC with a higher molecular weight exhibits better stability under varying pH and temperature conditions, which is essential in industries like construction where the material may be exposed to different environmental factors.
