PTFE Machining for High-Performance Components
PTFE machining is the process of manufacturing precision components from polytetrafluoroethylene (PTFE), a high-performance fluoropolymer known for its exceptional chemical resistance, low friction, and wide operating temperature range.
Accumatics specializes in machining PTFE components for sealing, fluid control, and high-performance industrial applications, supporting everything from prototype development to high-volume production.
PTFE Grades We Machine
Accumatics works with multiple PTFE grades to match application requirements:
-
Virgin PTFE (maximum chemical resistance)
-
Filled PTFE (glass, carbon, graphite, PEEK for wear resistance)
-
Modified PTFE (TFM grades for improved sealing performance)
Material selection is based on load, wear, temperature, and chemical environment.
Why Choose PTFE for Machined Components?
PTFE is one of the most widely used engineering plastics for sealing and chemical-intensive applications.
Key advantages of PTFE:
-
Near-universal chemical resistance
-
Extremely low coefficient of friction
-
Wide operating temperature range (-200°C to ~260°C)
-
Non-stick, non-reactive surface
-
Excellent dielectric (electrical insulation) properties
-
Resistant to moisture and environmental exposure
