Rigid POLY-MOR material does not have any detrimental effect on the environment due to decomposition or degradation.

Rigid and flexible POLY-MOR materials were tested at a disposal site and evaluated after three and five years. The POLY-MOR material, although discoloured, had not changed structure. Analysis of the leachate water did not show a noticeable deviation in composition from leachate water derived from waste which did not contain POLY-MOR material.

The stability of POLY-MOR material is well documented as noted previously. The chemical and solvent resistance of POLY-MOR material is quite good, and resistance to grease and oil is excellent. Rigid POLY-MOR materials will swell in aromatic oxygenated solvents, but will regain their original properties when dried. They are stable in water solutions of common detergents, salts, acids, and bases. Strong acids and bases attack the rigid POLY-MOR material and cause chemical degradation. Polar solvents can damage the POLY-MOR material, but it has limited solubility in these chemicals.

Rigid POLY-MOR material is inert to mildew and fungi and will not get mouldy or decay. The POLY-MOR materials do not nourish insects or rodents. They are chemically neutral. When exposed to sunlight, ultra- violet rays cause a yellowing of the POLY-MOR material and an embrittlement of the surface.
