Phenolic Resin Duct Thermal Stability
Jan 12, 2017

Its present shortened or cracks before using successive scale for temperature 140-175 ℃, phenolic resin duct in a wide temperature range with outstanding thermal stability. And have suffered not one use of irradiation reported temperatures of up to 180 degrees. Phenol

Formaldehyde air pipe foam components mixed with inert fillers can improve thermal stability, such as participation in 10% glass fiber phenolic foam suffered 800 ℃ high temperature 1 hour shortened or cracking. At low temperatures using phenolic foam without constraint. These work

Other organic foam could not do.
