Carbon Filled Ptfe Rod Products

Carbon Filled Ptfe Rod Products For produce bearings , Dielectric parts

PTFE rods filled with(carbon ,graphite ,glass fiber) :
PTFE resin,filled with some filling stuff,can prolong the life of products and strengthen the performance,eg:Graphite,Carbon ,Glass fiber ,bronze

Description :

PTFE Rod is often chosen to produce bearings because of its very low friction and also for its free running ability. Because of its ability to conform to shape otherwise known as flow, PTFE Rod is used for seals in valves, this is because it can conform to shape and create a high specification valve seal. PTFE Rod can easily be machined but due to the surface softness, care must be taken in lathe jaws or high compressive loads, which may cause distortion. Another important element to remember regarding PTFE Rod is the coefficient of expansion due to heat changes; this can be uneven with PTFE and may cause distortion in components.

Properties:

1.Working temperature:-180~+260°C
2.Melting point:327°C
3.Yield strength: 23MPa
4.Density: 2200 kg/m3
5.Coefficient of friction<0.10
6.Strong chemical-resistant


Specifications:

PTFE Rod is manufactured in two distinct ways, extruded PTFE Rod is the most popular and is relevant to smaller sizes, Moulded PTFE Rod is relevant to the diameters over 100mm in size, smaller sizes are also available in extruded form.
(a) Sizes Availabe,
-Extruded Rod Min. Diameter= 5mm, Max. Diameter= 150mm,
Length= normal 1 m, or according to customer's request
-Moulded Rod Min. Diameter= 5mm, Max. Diameter=300mm,
Length: Max. 300mm
(b) Extruded Rod Diameter 4~9mm made from dispersion PTFE resin; Diameter 10~50mm made from dispersion PTFE resin

Features of PTFE rods:

Exceptional chemical resistance.
Low dielectric constant and loss factor and is stable across wide temperature and frequency range.
Useful mechanical properties from cryogenic temperatures at 500°F (280°C).
Low coefficient of friction.

Application:
