Dishwasher Safe Plastic Glassware
Plastic glasses are made from a variety of different plastics. The cost of item is based on the quantity of plastic used, the quality of the plastic and the length of the annealing process used to set the plastic rigid.
A glass may have the heavy feel of a normal high quality glass but, if it's made from acrylic or low grade polycarbonate, then any exposure to heat could fracture or cloud your plastic glasses. Dishwashers, microwaves, exposure to direct sunlight and even washing-up water could ruin a glass that looks and feels great in the shop.
At Posh Plastics we only sell plastic glasses made from high quality polycarbonate. All of our products are safe to use in the dishwasher* and to expose to heat. Even our lighter weight products have been tested through 2000 dishwasher cycles.
The Thunder plastic glasses are designed to be made with more plastic, to give extra weight and a more realistic feel to those drinking from them. Many people will drink from a Thunder glass and have no idea that the glass they have just used is made from plastic.
The annealing, or baking process, that the glasses go through, bakes the plastic to increase the durability. As this represents the highest cost to the production process, many manufacturers shorten this stage. Thunder glasses are considered the clearest, most durable plastic glasses available because of the length of this baking process and are therefore slightly more expensive.
Given that all polycarbonate glassware will last quite a long time, the cost difference over time makes Thunder a better value product than cheaper plastic glasses.
*All of our polycarbonate products are safe wash in industrial and domestic dishwashers, up to 140°F/60°C, in the top rack. Products from RB Drinks are safe to wash on cycles with temperatures up to 265°F/130°C. This would be safe to wash in top-end domestic dishwashers on higher-intensity cycles. Check the temperature ranges of your cycles with the manufacturer to ensure that you cause no damage to your glassware.
