What are polycarbonate glasses? Polycarbonate glasses have the ability to look just like real glasses but are far more durable. A polycarbonate glass is virtually unbreakable and can be used anywhere that you want to avoid the chance of having broken glass around. These are ideal for nightclubs, pubs and outdoor events, as a dropped glass won't break and pose a threat to staff and Polycarbonate can be used in a glasswasher as it avoids going cloudy or hazy for around 500 washes. Polycarbonate glasses can be used as a direct replacement to glass, and you can even get polycarbonate pint glasses that are nucleated to nurture the head on your beer.
