PTFE Extruded Tube Uses
Medical Industry Uses: PTFE extruded tubes are used in medical devices and equipment, such as such as catheters, endoscopes, and surgical instruments.
Chemical Industries: Filled PTFE extruded tubes, with fillers like glass fibers or carbon, are used in the chemical industry to enhance the mechanical properties and chemical resistance of PTFE, making them suitable for handling corrosive chemicals.
Electrical Engineering: PTFE extruded tubes are widely used in electrical applications due to their exceptional electrical insulation properties. They serve as insulators, providing insulation and protection against high voltages and harsh environments for wires, cables, and electronic components.
Mechanical Engineering: PTFE extruded tubes find application in mechanical engineering. They are used as bearing pads, bushings, or gaskets to provide low friction, high-temperature resistance, lubricity, wear resistance, and thermal stability in various mechanical systems.
PTFE Extrusion Tube Process
Mixing: through the mixing machine to polytetrafluoroethylene powder and extruder mix.
Storage: storage at 25℃ for 24 hours.
Extrusion molding: extrusion molding through the extruder.
Sintering: the product into the sintering furnace for sintering.
Cooling: after sintering cooling.
The polytetrafluoroethylene pipe produced by extrusion process solves the problem of poor shrinkage of polytetrafluoroethylene pipe under heat, which can not effectively improve the corrosion resistance, electrical insulation and anti-viscosity of the workpiece.
Good deal: buying from seller
