Hydrochlorofluorocarbons (HCFCs) are a group of compounds, whose structure is very close to that of Chlorofluorocarbons (CFCs), but including one or more hydrogen atom. However, they are much less stable.
HCFCs are also part of a group of chemicals known as the volatile organic compounds (VOCs).
HCFCs are often now used as blowing agents during the manfacture of foam insulation products. Especially since the complete eradication of CFCs in the UAE, Qatar and Oman in 2010.
