Plastic Properties of Polytetrafluoroethylene (PTFE)

 

Polytetrafluoroethylene (PTFE) shows a remarkable chemical resistance and it is insoluble in all known solvents. It is attacked only by molten alkali metals and by fluorine at high temperatures. PTFE is incombustible and may be used up to 260°C (300°C for short periods). PTFE's coefficient of friction is extremely low and it shows the effect of self lubrication with constant mechanical properties which makes it particularly suitable for bearings, joints, O-rings, stirring bars, hazardous materials bottle pouers, syringes, crucubles, evaporating dishes etc. PTFE may be shaped by compression and sintering into bottles and beakers where its chemical stability and non-wettability make it suitable for use in extreme circumstances. Dynalab Corp's plastic fabrication shop fabricates thousands of catalog and custom PTFE products.

PTFE Bottles

PTFE Syringe with plunger

Non-sticking PTFE syringes are virtually
immune to chemical attack with a working
temperature from cryogenic to 260°C.

PTFE Bottles above are available in capacities from 1mL to 2000mL. Virtually immune to chemical attack, only attacked  by some fluorine containing compounds at high temperature and molten alkalis metals.
