PTFE Raschig ring
Products Introduction
Polytetrafluoroethylene (Teflon or 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.
Rasching ring is one of the earliest artificial fillers used in the industry. It is usually made of ceramic or metal sheet, and its height is equal to its diameter. The commonly used size is 25mm~75mm (some as small as 6mm and as large as 150mm). The ceramic wall thickness is 2.5mm~9.5mm, and the metal ring is 0.8mm~1.6mm. The wall of the ring should be as thin as possible when the strength permits. Although the mass transfer performance of the Raschig ring is not ideal, it is still used by some factories due to its simple structure, easy manufacture and low price.
