Polymethyl methacrylate is resistant to dilute inorganic acids, but concentrated inorganic acids can erode it, and it can resist alkalis, but warm sodium hydroxide and potassium hydroxide can erode it, and it can resist salts. And fats and oils, resistant to aliphatic hydrocarbons, insoluble in water, methanol, glycerin, etc., but can absorb alcohol swelling, and produce stress cracking, not resistant to ketones, chlorinated hydrocarbons and aromatics Its solubility parameter is about 18.8 (J / CM3) 1/2, which can be dissolved in many chlorinated hydrocarbons and aromatic hydrocarbons, such as dichloroethane, trichloroethylene, chloroform, toluene, etc., vinyl acetate and acetone can also make it Dissolve.
Polymethyl methacrylate has good resistance to gases such as ozone and sulfur dioxide.
