Alro Plastics offers
PTFE or TFE (polytetra-fluoroethylene), a very dense material having a density of
2.13 - 2.19 grams/cc. PTFE is well known for its
chemical resistance. It is insoluble in all organics with the exception of a few
exotics. Electrical properties are excellent. Impact
strength is high but its resistance to wear, tensile strength and creep resistance
are low in comparison to other engineering materials.
Mechanical properties can be improved by adding fillers such as glass fibers, bronze,
carbon, and graphite. PTFE has an extremely low
coefficient of friction. Very few materials will stick to it. It has useful properties
from cryogenic temperatures up to 260oC (550oF).
PTFE is also offered in FDA compliant grades for food grade applications.
Features:
- Excellent electrical properties
- High impact strength
- Great chemical resistance
- Wide range of temperatures
Applications:
- Bushings and bearings
- Conveyor rollers
- Doctor blades
- Gaskets and seals
- Coil separators
- Conductor, layer, ground insulation
