White Ptfe Teflon Gasket, Round, Thickness: 1 mm

PTFE (Polytetrafluoroethylene) is a unique material. It is one of the most valuable engineering materials available due to its versatility. PTFE has an unmatchable profile of unique properties; a fluorocarbon polymer with outstanding chemical and thermal resistance, so it can be used to seal against virtually any chemical under a huge range of operating temperatures. As a semi-crystalline plastic that doesn't absorb UV light, it also shows excellent resistance to sunlight.
