What is phenol resin used for?
Phenolic resins are good for high-temperature applications where parts must meet fire safety standards. Phenolic resins are used in a wide range of applications, including electronics, ballistics, mine ventilation, offshore water pipe systems, aerospace, rail and mass transit.
How is phenol formaldehyde produced?
Phenol formaldehyde (PF) resin is a polymer condensate obtained from the condensation reaction between phenol and formaldehyde in the presence of an alkaline catalyst [1-7]. PF resin is usually synthesized with formaldehyde (liquid formalin) instead of paraformaldehyde (powder) [2, 7, 8-12].
Is phenolic amorphous?
At high temperature, phenolic resins form a char of amorphous carbon. This means phenolic bonded carbon materials can be heat treated to yield an all carbon structure.
Is phenolic resin poisonous?
Amino and phenolic resins contain formaldehyde, which is highly toxic by inhalation, highly toxic by eye contact and ingestion, and moderately toxic by skin contact.
What industries use formaldehyde?
