Teflon rod is a kind of rod formed by molding, paste extrusion or plunger extrusion process with unfilled polytetrafluoroethylene resin (which may contain recycled polytetrafluoroethylene resin). It has good high and low temperature resistance, corrosion resistance, low friction and other advantages. Therefore, it has a wide range of applications and is suitable for gaskets, seals and lubricating materials working in corrosive media, as well as electrical insulation parts materials used at various frequencies.

Teflon rods are mixed with polytetrafluoroethylene resin (which can contain recycled polytetrafluoroethylene resin) and additives, then put into a mold for compaction, and then through a certain pressure, the mold is kept at a certain temperature. After a period of time, the powder is compacted and coalesced together to form polytetrafluoroethylene blanks, then the blanks are taken out, heated to the melting point in a sintering furnace, and the particles of polytetrafluoroethylene resin are melted into a whole, and cooled into semi-finished product or finished product is made, therefore, there are three main factors that affect the performance of PTFE rods, one is PTFE resin, the other is the production process, and the third is the heating temperature and humidity. Specifically, it is: PTFE resin will affect the quality of PTFE rod finished product. It mainly refers to the fluidity of PTFE resin. If the raw material-PTFE resin has poor fluidity during the production of PTFE bars, it is easy to decompose, and corrosive gas will be generated after decomposition.
The production process will affect the quality of the finished PTFE rod.
The powder resin of PTFE rod is usually formed by powder metallurgy method and then sintered. Latex resin is generally treated by cold extrusion and re-sintering process, which can form anti-corrosion layer on the surface of articles. If the product is required to have light transmittance and toughness, rapid cooling should be adopted, and then extrusion molding should be adopted, thus producing extruded PTFE rod.

Polytetrafluoroethylene (PTFE) is an engineering plastic with excellent comprehensive properties, specifically manifested in: a wide range of high and low temperature use, the use of temperature -180 ∽ 250 ℃; Excellent chemical stability; High electrical insulation; Outstanding surface non-tackiness; Good lubricity; Excellent aging resistance.
Polytetrafluoroethylene (PTFE) plates are made by molding and turning; rods are made by extrusion, pushing or molding; and films are made by turning.
Plates and rods are mainly used for corrosion-resistant gasket seals, linings, lubricating materials and electrical insulation parts used at various frequencies; films are used for capacitor media, wire insulation, electrical instrument insulation, etc.
