XCELTHERM® HFF

High flash point of greater than 410°F (210°C) as measured by Pensky-Martens Closed Cup method (ASTM D93), petroleum based, non-toxic for use up to 600°F (315°C). Recommended for use in wood kilns, paper and packaging, wood panel production, marine transportation or any application where a higher than usual flashpoint is required.
