PTFE

The physical properties of PTFE

Polytetrafluoroethylene (PTFE) is very non-reactive and is often used in containers holding reactive and corrosive chemicals. According to DuPont, its melting point is 600 K (327 °C; 620 °F). It maintains high strength, toughness and self-lubrication at low temperatures down to 5 K (-268.15 °C; -450.67 °F), and good flexibility at temperatures above 194 K […]

Fluoric polymers (PTFE/PVDF)

Fluoropolymers have excellent, almost universal chemical resistance. They can be used both at high and very low temperatures (-260 to +260°C). They also possess outstanding resistance to weathering (UV-stability). Due to the low coefficient of friction, they are often used as sliding materials or as corresponding additives in other high-performance plastics. TECAFLON PVDF (PVDF) Polyvinylidenefluoride […]

Fluoropolymers Properties

Properties Fluoropolymers are produced from alkenes in which one or more hydrogen atoms have been replaced by fluorine. The most important members are polytetrafluoroethylene (PTFE), polychlorotrifluoroethylene (PCTFE), poly(vinyl fluoride) (PVF) and poly(vinylidene fluoride) (PVDF) Due to the weak van der Waals forces, polyfluoroolefins have a very low coefficient of friction and very low surface tension […]
