RESISTANCE TO
CHEMICAL AGENTS

The chemical and solvent resistance of POLY-MOR expanded resins is very good, and resistance to grease and oil is excellent. Rigid expanded resins will swell in aromatic oxygenated solvents, but will regain their properties when dried. Strong acids and bases attack the rigid expanded material and cause chemical degradation. Polar solvents can damage the material, but have limited solubility in these chemicals.

The resistance of POLY-MOR expanded polymer resins to chemical agents has been evaluated as a function of loss of volume following prolonged exposure, and evaluated in the following categories:

  • Excellent resistance (loss of volume < 3%)
  • Good resistance (between 3% and 6%)
  • Fair resistance (between 6% and 15%)
  • Poor resistance (between 15% and 25%)
  • No resistance – do not bring into contact (strong solvent action or chemical attack)
