Which polymer is described as tough, corrosion resistant and chemical resistance and used for baths?

• A. PMMA
• B. LDPE
• C. UPVC
• D. HDPE

Answer: (A)

PMMA, or polymethyl methacrylate, fits this description well. It’s a tough, rigid thermoplastic with excellent chemical resistance, meaning it stands up to cleaners and other bathroom chemicals without corroding. It’s also well known for being used in baths: acrylic baths are produced from this material because it can be formed into smooth, curved shells and finished to a high-gloss, non-porous surface that’s comfortable to touch and easy to keep clean. The other options don’t fit as neatly for a bath shell: LDPE is too soft and flexible for a solid bath structure, HDPE is tough but not ideal for the glossy, smooth finish of a bath, and UPVC is highly resistant to chemicals and corrosion and is used mainly for pipes and fittings rather than the actual bath shell.
