Plastics Explained
The plastic glasses listed on this web site are made from a variety of different plastics, each with its own characteristics. Below is a short description of each type of plastic along with a table of characteristics to help you chose the type of glass you require.
Polycarbonate
Polycarbonate is a very hard wearing plastic and is used to make crash helmets and riot shields as well as plastic glasses. Our polycarbonate glasses are dishwasher safe up to and beyond 500 washes and are virtually unbreakable in normal everyday usage. For these reasons these glasses are recommended for use in pubs and nightclubs as well as household use.

SAN
SAN or Styrene Acrylonitrile is a hard wearing plastic and will take a lot of usage although it will crack if put under a lot of pressure. SAN glasses are dishwasher safe and can withstand high temperatures. These glasses are recommended for restaurant and household use.

Polystyrene
Polystyrene (PS) is a hard but slightly brittle plastic and is used to make reusable and disposable plastic glasses. The reusable polystyrene glasses are dishwasher safe for over 100 washes and heat resistant to 100°c. Polystyrene can be recycled and its resin identification code is to the right.

Polypropylene
Polypropylene (PP) is a thermoplastic polymer and used in a wide variety of applications including textiles, stationary, packaging and plastic glasses. Polypropylene can be recycled and its resin identification code is to the right.
