Product Description

Product Description

PFA, Perfluoroalkoxy is preferred when extended service is required in hostile environments involving chemical, thermal and mechanical stress. PFA proffers high melt strength, stability at high processing temperatures, excellent crack and stress resistance, low coefficient of friction and higher flex life.

PFA can be used in a wide range of temperatures: from -328°F/-200°C to 500°F/260°C. In comparison to other fluoropolymers, it demonstrates greater mechanical strength, stiffness and wear resistance. It has a low coefficient of friction and beneficial anti-stick properties.

The main fields of application are the semiconductor industry, medical sector, fluid handling in chemical, medical, pharmaceutical applications, seats for valves as well as other components of valves and pumps.

Main Properties & Application

• Outstanding chemical resistance
• Good electrical insulation performance
• Good resistance to high & low temperature
• Excellent weld-ability and processing properties
• Good crack-resistant performance
• Good non-sticky properties
• Higher thermal stability than FEP
• Working temperature of up to 500º F (260ºC)
• Lower permeability than FEP
• Combines attributes of PTFE and FEP
• Translucent
• Maintains mechanical strength at high temperatures
• Moisture absorption close to zero

PFA sheet applications:
• Chemical tank liners
• Semiconductor equipment components
• Pump and valve parts
• Electrical components
• Medical devices parts
• Food processing machinery components
• Bearings \ bushings \washers
