  • Reading food labels is not one of my favourite occupations, but is a necessary evil as I bring up a coeliac child.

  • Another crucial factor is the supplier's ability to consistently meet demand. A good HPMC supplier should have robust manufacturing capabilities and a stable supply chain, allowing them to fulfill orders promptly without compromising on quality. They should also be flexible, able to adapt to changing market conditions and customer needs.
  • In aqueous solutions, HEC is highly soluble at neutral pH values, forming stable, non-ionic solutions. It dissolves readily in cold or hot water, although hot water often accelerates the dissolution process. The solubility decreases as the temperature drops, a characteristic known as retrogradation. However, this can be counteracted by maintaining a constant stirring during the dissolution process.
  • In addition to these physical improvements, HPMC has environmental benefits. It allows for the reduction in the use of other additives, some of which may have a higher environmental impact. The use of HPMC can therefore contribute to more sustainable building practices.
  • Redispersible powder, a versatile and innovative material, has significantly reshaped the landscape of construction and industrial applications in recent years. This unique substance, also known as redispersible polymer powder or RDF, is a game-changer due to its exceptional properties and wide range of applications.
  • Acrylic-based redispersible polymer powders are also noteworthy
  • Cellulose ether is also widely used in the construction industry as a water-soluble polymer additive in cement-based products
