Cole-Parmer has no knowledge of possible effects beyond this period. It is resistant to most detergents, inorganic chemicals, aliphatic hydrocarbons, fats and oils, diluted acids … Properties like impact resistance, chemical resistance, light diffusion, UV filtering and optical effects can be easily modified by subjecting the base ingredient to various physical and chemical processes. Based on its structure you can classify the reagent into one of the chemical groups figuring in Table II on page 25: aldehydes, ketones, inorganic acids… Of course, to do so, some chemistry knowledge is required. Pmma chemical resistant 1. Materials used in the These include exposure time, chemical impurities, mixing of different chemicals, concentration, extreme temperatures or pressures, temperature and pressure cycling and mechanical stresses. The polymethyl methacrylate concrete is prepared with proper mix proportions, and tested for chemical resistance to eleven reagents such as acids, alkali, salts, oils, solvents and tap water according to the draft JIS (Japanese Industrial Standard), Method of Test for Chemical Resistance of Concrete in Aggressive Solutions. We do not have a current detailed Chemical Resistance Chart for PMMA. Plastic may even tolerate for years. A = No Attack, possibly slight absorption. It is especially attractive for its high, optical quality transparency and useful mechanical properties. Negligible … — Satisfactory to 72° F. 3. Stress cracking chemicals include detergents, surfactants, lubricants, oils, ultra-pure water and plating additives such as brighteners and wetting agents. To add on, this grade has stronger chemical resistance in comparison to typical SUMIPEX® PMMA grades, hence it is widely used in the automotive industry for manufacturing of rear tail lamps and for applications which requires higher chemical resistance, such as cosmetic bottles and containers. Some effect after 7 days of constant exposure to the reagent. It is resistant to most detergents, inorganic chemicals, aliphatic hydrocarbons, fats and oils, diluted acids … PMMA is an economical alternative to polycarbonate (PC) when tensile strength, flexural strength, transparency, polishability, and UV tolerance are more important than impact strength, chemical resistance, and heat resistance. 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.
