PTFE Release Fabric is a medium porosity PTFE coated glass fabric, sometimes known as Teflon Peel Ply, and is ideal for use on flat or single curvature mouldings. The PTFE release coating ensures easy release from the laminate without fear of contamination, and it's designed for use in extreme temperature and pressure processing conditions.
PTFE (Polytetrafluoroethylene) coated fabrics, such as this release fabric, are utilized in a variety of composite manufacturing processes due to their release properties and resistance to high temperatures and abrasion. These fabrics are often made from woven fiberglass cloth with a clear PTFE coating, making them non-toxic, odorless, tasteless, and FDA compliant. They offer exceptional durability and extremely low elongation, with dimensional stability ranging from -100°F to +500°F (-73°C to 288°C).
PTFE-coated fiberglass fabrics are used in processes including hand lay-up, open mould, and vacuum bag. Their flexibility allows them to conform nicely to moulds, and their release characteristics enable easy and clean removal from moulds. Additionally, they are heat-resistant and abrasion-resistant, making them suitable for high-performance applications. Depending on the application, these fabrics can be used for single-use or multiple uses, with the heavier PTFE content offering better release properties.
PTFE Release Fabric is a versatile tool in composite manufacturing, aiding in achieving high-quality, durable, and precise composite materials, especially in demanding conditions. It's an essential component in industries where precision, durability, and resistance to extreme conditions are paramount, such as aerospace, automotive, and marine engineering.
