PTFE
Polytetrafluoroethylene (PTFE), also known as Teflon, is a versatile plastic material with exceptional properties. It is chemically resistant, non-stick, and can withstand high temperatures (-200°C to +260°C). PTFE is commonly used in industries such as chemical processing, food processing, electrical engineering, automotive, and medical due to its unique combination of properties.
Properties
l Resistant to low and high temperatures (-200°C ~+260°C)
l Non-stickiness, low water absorption
l Non-flammable, corrosion resistance
l Oxidation resistance
Applications
l Used in various wires and cables, battery electrodes and other electronic and electrical appliances.
l It is also used for gasket seals and lubricating materials for working in various media, as well as electrical insulating parts used at various frequencies.
Specification
l Width: 5~1300 mm
l Thickness: 0.03~1.0 mm
l Length can be re-processed according to customer requirements.
