This is a FLEXIPAN from DEMARLE. It's a flexible, non-stick baking mold made from a combination of silicone and fiberglass. The usable temperature range is wide, from -40°C to +250°C, allowing for use with baked goods in the oven to frozen desserts. There's no need to grease the mold, and baked goods and frozen items can be easily removed. It has excellent durability and is said to withstand over 2500 bakes. Thank you for viewing.
