Benefits
The benefits of PTFE applications
High chemical resistance.
Not attacked by acids, bases, and most organic solvents.
Withstands up to + 260 ° C continuously.
Tough at low temperatures down to -160 ° C.
Lowest friction of all plastics.
Not degraded by UV radiation.
Not attacked by microorganisms.
Good electrical and dielectric properties.
Very low water absorption.
Restrictions
The restrictions of fluorescent 500
High melt viscosity makes the material difficult to work with.
Poor creep resistance.
High density relative to other plastics.
Attacked by molten alkali metals, fluorine gas, oxygen difluoride, and chlorine trifluoride (except PTFE).
Fluorescent 500 has nine times greater resistance to deformation under load than unfilled PTFE. The plastics coefficient of linear thermal expansion approaches the expansion rate of aluminum and often eliminates fit and clearance problems. Fluorescent 500 has better wear characteristics, maintains low frictional properties, and is non-abrasive to most mating materials. The PTFE plastic is most commonly used in such things as:
