What chemicals should acrylic display stands avoid contact with?

Acrylic display stands are made of polymethyl methacrylate (PMMA), which has good chemical stability but is sensitive to certain organic solvents and corrosive substances. Contact with these substances may cause surface damage, performance degradation, or appearance deterioration. The following are categories of chemicals that must be avoided, along with specific examples:

1. Organic solvents: Directly corrode the surface, causing whitening, cracking, and dissolution.
Organic solvents destroy the bonds between acrylic molecules, causing surface swelling, loss of gloss, and even complete dissolution. The following should be strictly avoided:

Esters: Ethyl acetate (commonly used in adhesives and paint thinners), butyl acetate (paint solvent).
Ketones: Acetone (main component of nail polish remover), butanone (industrial cleaner).
Halogenated hydrocarbons: chloroform (trichloromethane, a component of some acrylic adhesives), dichloromethane (a common component of adhesive removers), carbon tetrachloride.
Aromatic hydrocarbons: benzene (solvent, chemical raw material), toluene (paint and adhesive thinner), xylene (printing ink solvent).
Others: alcohol (high-concentration ethanol, prolonged contact may cause surface dullness), gasoline, kerosene, banana oil (mixed organic solvent, highly corrosive).

2. Strong acids and alkalis: Corrode materials, causing rough surfaces and discoloration Although acrylic is resistant to weak acids and alkalis, prolonged or high-concentration contact with strong acids and alkalis will cause a chemical reaction, damaging the surface integrity: Strong acids: Sulfuric acid (battery fluid, industrial acid), hydrochloric acid (main ingredient in toilet cleaners), nitric acid (chemical raw material). Strong alkalis: Sodium hydroxide (caustic soda, commonly found in drain cleaners), potassium hydroxide (industrial alkali), and ammonia water (used in some glass cleaners and fertilizers).
