A comprehensive understanding of UltraCarb
Luke Hollingbery completed a PhD entitled “Decomposition and Fire Retardancy of Naturally occurring mixtures of Huntite and Hydromagnesite”.
Academical articles on Huntite and Hydromagnesite
During the course of the PhD project, Dr Hollingbery started to write articles for submission into international academically refereed journals. To date five of his papers have been published, these are:
Published in Thermochimica Acta by L A Hollingbery and T R Hull
Published in Polymer Degradation and Stability by L A Hollingbery and T R Hull
Published in Polymer Degradation and Stability by T R Hull, Artur Witkowski, and L A Hollingbery

UltraCarb as fire-retardant
We now have a far more detailed appreciation of how the UltraCarb product acts as a fire retardant in polymer compounds. Highlights of this work include:
- A detailed mechanism for the decomposition of both huntite and hydromagnesite
-
A new appreciation for the fire retardant action of both huntite and hydromagnesite
- Hydromagnesite is active in the early stages of the fire, endothermically releasing water and carbon dioxide; this helps to reduce the initial spread of the fire
- Huntite is active in the later stages of the fire; the platy particles build a strong char layer (far stronger than other mineral flame retardants) which inhibits the further development of the fire.
- Both huntite and hydromagnesite have an active part to play in fire retardancy; something which had not been previously quantified.
This in-house knowledge enables us to confidently and accurately assist customers to optimise their polymer compounds with the UltraCarb grades required to meet their requirements.
