Product Description
Polytetrafluoroethylene
PTFE is considered a high performance plastic, with a step up of engineering plastics such as polyamide and polyacetal in the "hierarchy" of polymers, as well as its price. PTFE has very high viscosity, which prevents it from being processed in the same manner as other thermoplastics (injection molding, extrusion etc), so its use is required in powder form, for compression molding and subsequent sintering at high temperatures.
Despite having high impact resistance, PTFE relative to engineering plastics has low tensile strength, creep and to the use, in some applications requiring the incorporation of fillers such as fiberglass, bronze, carbon fiber, stainless steel and synthetic coal. Also common is the incorporation of graphite and molybdenum disulphide to further improve their sliding and anti-adhesive properties, since the coefficient of friction of PTFE is lower than almost all other plastics(remember the Teflon used as non-stick coating in pans?).
Features:
-High impact resistance

-Useful mechanical properties even at cryogenic temperatures
-Low resistance to the use
-Low tensile strength
-Low creep resistance
-Antiflame
Application:
Stadium coverage, sealing tape, non-stick coating, gaskets, grease component, piercing, pipe coating, valves, tubes replacing human veins etc.
