PTFE Raschig ring
Products Introduction
Polytetrafluoroethylene (PTFE), commonly known as "Plastic King", is a polymer compound formed by polymerization of tetrafluoroethylene. It has excellent chemical stability, corrosion resistance, sealing properties, high lubrication and non-stickiness, electrical insulation and good resistance to aging.
PTFE Raschig Ring packing has the advantages of strong sealing, high pressure resistance and strong corrosion resistance. It has excellent sealing material performances. When used alone or in combination with other packings, it is especially suitable for static sealing parts under high temperature and high pressure conditions. In addition to aqua regia and strong oxidizing acids, it can be safely used in all media.
