Acrylic PMMA Plastic Chemical Compatibility


What is acrylic plastic?Acrylic (PMMA, polymethyl methacrylate) is a widely used amorphous thermoplastic polymer. It is best known by its trade names Lucite® and Plexiglas®.

Acrylic is tough, durable, easy to shape and relatively inexpensive. It is especially attractive for its high, optical quality transparency and useful mechanical properties. Acrylic plastic also has excellent resistance to ultraviolet (UV) light and weathering. It does not yellow over time.

Acrylic (PMMA) plastic and these chemical compatibility guidelines

Things to keep in mind when referring to this chemical compatibility guideChemical resistance information is based on data provided by testing done under laboratory conditions. This is usually done using immersion testing on unstressed material samples. Also, immersion test procedures are not generally standardized.

 


Why lab testing is not enoughIn a lab, it is not possible to cover all the possible variables that might exist in actual operating conditions. This is because so many factors can affect a materials chemical resistance. These include exposure time, chemical impurities, mixing of different chemicals, concentration, extreme temperatures or pressures, temperature and pressure cycling and mechanical stresses.


Stress CrackingCertain combinations of chemical exposure and mechanical stress can also cause environmental stress cracking. Environmental stress cracking is not purely a result of chemical attack. A combination of three factors cause stress cracking: tensile stress, a stress cracking chemical and the inherent susceptibility of a thermoplastic to stress cracking. Stress cracking chemicals include detergents, surfactants, lubricants, oils, ultra-pure water and plating additives such as brighteners and wetting agents.


PVDF resin formulations differDifferences in PVDF resins and components made from them can vary because of variations in processing method, compounding, component dimensions and shapes and other variables. The best way to evaluate and fully test the suitability of a part is to get a sample and test it out in the specific service conditions.
 

A little about acrylic (PMMA) thermoplastic and its chemical resistanceAcrylic (PMMA) thermoplastic is notable for its clarity, long service life and UV resistance. It is resistant to most detergents, inorganic chemicals, aliphatic hydrocarbons, fats and oils, diluted acids and concentrated alkalis at room temperature. This chart is a guide to PMMA compatibility with a wide range of chemicals found in industrial, commercial and laboratory applications.
