Flexible bakeware has changed the way that pastry chefs work. The non stick flexible molds and trays do not have to be greased and will still unmold without breakage. Flexipans are made with a combination of fiberglass and silicone. This allows the molds to be flexible, and gives it it's non stick quality. The combination also gives the bakeware a longer life, making it possible to use them two or three thousand times before the first signs of sticking.The ease of cleaning also makes these flexible bakeware such a desirable tool.
