Ball Valve Seats Materials Selections
Material Name	Compound %	Main Properties	Color
PTFE	/	Very low coefficient of friction and excellent chemical resistance.	White
Glass Filled PTFE	Up to 40%	Improved ware resistance, compression strength, creep resistance, chemical resistance. Good performance in oxidising environment, good creep resistance.	White cream
Carbon Filled PTFE	Up to 35%	Improved electrical and termal conductivity, resistance to load, low coefficient of friction in dry, water, steam applications, chemical resistance. Superior ware resistance increase and low friction properties.	Black
Graphite Filled PTFE	Up to 25%	Improve wear resistance, decrease friction and increase sliding properties against soft metals- chemical inertness. Improve the temperature resistance in some way.	Black
Bronze Filled PTFE	Up to 60%	Improved compression strength, wear resistant, high thermal conductivity, resistance to abrasion. Reduced chemical resistance.	Dark Brown
Molybdenum disulphide(MoS2) Filled PTFE	up to 5%	Increased PTFE properties of hardness and wear resistance. Increased sliding properties and decrease friction.	Blue azure
PEEK Filled PTFE	Up to 20%	Increased thermal resistance, sliding properties, surface hardness. Superior properties on dynamic applications.	Light Brown
PEEK	/	Excellent mechanical properties including strength, rigidity, impact resistance, low wear rate and low coefficient of friction, retained over a wide range of service temperatures	Light Brown
PEEK compound	/	Improves technical and chemical properties like deformation under load, wear resistance, thermal expansion and electrical conductivity.	/
PVDF	/	Resistant to UV radiation and offers high mechanical strength and abrasion resistance.	Beige
PCTFE	/	Better mechanical properties than other fluoropolymers, low permeability	Translucent
PFA	/	Excellent chemical and temperature resistance, electrical insulation and excellent process ability.	Natural
