Description

It is a fluorinated polymer which presents an exceptional behavior at very low temperatures. It is usable in continuation from -200°C to +150°C with allowable peaks at 200°C. It is non-inflammability, has excellent chemical and radiation resistance, good barrier properties, is insensitivity to oxygen and water with good electrical properties. The processing is critical but can be done by extrusion, injection and compression molding.
