Walk through any shop of reusable plastic wine glasses and nearly everything good is one of two materials. Tritan is a copolyester made by Eastman. Acrylic is PMMA, the plastic behind Plexiglas. From a metre away they look alike. In daily life they behave very differently.
Side by side
Acrylic vs Tritan
| Tritan | Acrylic | |
|---|---|---|
| Clarity | Very clear, close to glass | The clearest plastic, bright shine |
| Toughness | Shatter-resistant, bounces off stone | Brittle; can crack on a hard drop |
| Dishwasher | Yes, top rack | Hand-wash; heat and detergent wear it down |
| Scratches | Resists better | Scratches more easily |
| BPA | Made without BPA or BPS (Eastman) | Not made with BPA |
| Colours | Mostly clear | Every colour and pattern |
| Feel | Firm, some weight | Rigid, light |
| Price | Usually higher | Usually lower |
Which one for where
Pool and hot tub
Tritan. Wet tiles, wet hands and dropped glasses are exactly what it is made for.
Boat
Tritan, stemless. Acrylic can crack on a hard deck.
Patio dinner
Either. Acrylic if you hand-wash and like colour; Tritan if it all goes in the dishwasher.
Picnic
Either, packed with a cloth. Both scratch when glasses rub together.
Party you host every summer
Tritan. One set, many seasons, straight into the dishwasher.
Coloured theme table
Acrylic. It is where the colours are.
Safety: what each one is made of
Neither material is made with BPA, the chemical behind the worries about older polycarbonate glasses. Eastman says Tritan contains no BPA or BPS. A 2011 study questioned hormone-like activity in some BPA-free plastics, Tritan included, and Eastman disputes it. Polycarbonate, the third plastic you may still see in bars, is made with BPA, and the EU banned BPA in food-contact materials from 20 January 2025. The full safety answer is in what is Tritan: is it safe.
How to tell them apart in a listing
- Read the material line. Good sellers name it. “Plastic” or “BPA-free” alone tells you nothing about which one it is.
- Read the washing line. “Dishwasher-safe” points to Tritan. “Hand-wash recommended” points to acrylic.
- Look at the colours. A rainbow of tints is almost always acrylic.
- Check the base. Both carry recycling code 7, so the code will not settle it.
And the wine?
No published test compares the same wine in Tritan and acrylic. In both, the bowl shape does most of the work: choose a bowl that narrows at the top, a smooth rim, and a size that leaves room above the pour. White, rosé and sparkling wines, served cold, suit plastic glasses best.

Acrylic vs Tritan: your questions
Which is better, acrylic or Tritan?
Tritan for most people: it survives drops and the dishwasher. Acrylic is slightly clearer, comes in more colours and is usually cheaper, but it is brittle and needs hand-washing.
Which is clearer, acrylic or Tritan?
Acrylic is the clearest plastic. Tritan is very clear too and stays clearer in the dishwasher.
Are acrylic and Tritan BPA-free?
Neither is made with BPA. Eastman says Tritan contains no BPA or BPS. Polycarbonate, an older plastic, is made with BPA.
Which is better for the pool?
Tritan. It survives drops on tiles and goes in the dishwasher afterwards.
