PTFE (Polytetrafluoroethylene)

PTFE (Polytetrafluoroethylene) is a synthetic fluoropolymer known for its exceptional chemical resistance, low friction coefficient, and non-stick surface properties. It is widely used in chemical processing equipment, pharmaceutical manufacturing, food handling systems, and sealing applications where corrosive environments or sterile conditions demand a material that won't degrade or contaminate. Engineers select PTFE when standard plastics or metals fail due to chemical attack, when low-friction sliding surfaces are critical, or when non-reactivity with aggressive fluids is essential—though its relatively low stiffness and creep under sustained load require careful design consideration.
