Makrolon polycarbonate sheet may be used in a diverse range of environmental conditions. However, as with any thermoplastic, some environmental conditions have proven to be detrimental to Makrolon sheet. Varying degrees of stress, strain and temperature may also alter the resistance of Makrolon sheet; consequently fabricated parts should be tested thoroughly under actual in-service conditions prior to final design.

In general, Makrolon sheet has good resistance to water, organic and inorganic acids, neutral and acid salts and aliphatic and cyclic hydrocarbons. Alkalines, amines, ketones, esters and aromatic hydrocarbons attack Makrolon. Solvents for Makrolon are: methylene chloride, ethylene dichloride and dioxane

This chemical and solvent resistant listing is intended to assist designers in determining whether Makrolon sheet can be used in certain environments. It is very important to test prototype parts under end-use conditions for final verification of performance. All data is based on 70°F and 0% strain.

Makrolon sheet has good resistance to water up to approximately 150°F. Above this temperature, the effect of moisture is time-temperature related. Exposing Makrolon sheet to repeated steam cleaning or dish washing can create hydrolic crazing. The result can be a clouding of the surface and ultimately a loss of physical strength properties.
