seals
lubricating materials
that work in corrosive media, as well as electrically insulating parts used at various frequencies. Rods made of unfilled polytetrafluoroethylene resin (which may contain recycled polytetrafluoroethylene resin) through molding paste extrusion or plunger extrusion processes.
Characteristics
The operating temperature range is very wide (from degrees to degrees Celsius).
Basically resistant to all chemicals except some fluorides and alkaline metal liquids.
Excellent mechanical properties including aging resistance especially for bending and swing applications.
Outstanding flame retardancy (compliance and test procedures are specified as flame retardant materials in air.
Excellent insulating properties (regardless of frequency and temperature)
Very low water absorption and It has a series of unique properties such as self-lubrication and non-stickiness.
Applications
There are two types of PTFE rods: push rods and molded rods. PTFE has the best performance among known plastics. Excellent chemical corrosion resistance and dielectric properties, can be used at temperatures of ℃, and has the lowest friction coefficient. It is mainly suitable for some long products and non-standard mechanical parts seals/gaskets, ring materials, wear-resistant plates/seats for electrical insulation Parts corrosion resistance industry machinery parts lining petroleum and natural gas petrochemical industry chemical industry instrument equipment manufacturers, etc.
Application fields of PTFE rods
Chemical industry
Can be used as anti-corrosion Materials can be used to manufacture various anti-corrosion parts, such as pipes, valves, pumps and pipe joints. In terms of chemical equipment, it can be used to make linings and coatings for reactor distillation towers and anti-corrosion equipment.
Mechanical aspects
Can Used as self-lubricating bearing piston ring oil seals and sealing rings. Self-lubricating properties can reduce wear and heat of machine parts and reduce power consumption.
Electronics and electrical appliances
Mainly used to manufacture various wires, cables, batteries, electrodes and batteries Diaphragm printed circuit board, etc.
Medical materials
Utilizing their heat-resistant, water-resistant and non-toxic properties, they can be used as materials for various medical devices and artificial organs. The former such as sterilized filters, beakers, artificial heart and lung devices, The latter, such as artificial blood vessels, heart and esophagus, etc. have been widely used as sealing materials and filling materials.
