Phenol formaldehyde (PF) resin have excellent resistance to heat and chemicals, making them ideal for volatile environments. They are non-conductive and flame resistant, so they are a good choice for any environment that require compliance with fire safety, smoke emission, combustion and toxicity standards.
In addition, phenol formaldehyde resin properties include good thermal insulation, low density and excellent durability. They are unaffected by corrosion and impervious to most chemicals. They are easy to mold into a variety of shapes and complex contours, making them adaptable to custom equipment or environments.
Moujen's basic limit switch: MJ2-1 series with the suffixes "PH" or "PH-20", are made with these phenolic materials as their enclosures.
