Disc and Liner Materials

PTFE

• The standard material choice unless other characteristics are needed
• Void-free material isostatically molded from virgin PTFE. 
• High density PTFE >2.16g/cm3
• Guaranteed lining thickness of at least 3mm (0.125”), plus high crystallinity
• FDA-compliant
• Operating temperature: -40⁰F to 400⁰F (-40⁰C to 200⁰C)

Material Characteristics

UMPE

• Best option for abrasion resistance
• Lower temperature and chemical resistance compared to PTFE
• Optional FDA compliance
• Operating temperature: -40⁰F to 185⁰F (-40⁰C to 85⁰C)

Material Characteristics

Abrasion-Resistant PTFE

• Carbon-reinforced PTFE
• Used when temperature or chemical resistance is needed with abrasives
• Not FDA-compliant
• Operating temperature: -40⁰F to 400⁰F (-40⁰C to 200⁰C)

Material Characteristics

Anti-Static PTFE

• Graphite-reinforced PTFE
• For explosive medias, liner is conductive
• ATEX-compliant
• Surface resistance < 106Ω
• Volume resistance < 106Ω cm
• FDA-compliant
• Operating temperature: -40⁰F to 400⁰F (-40⁰C to 200⁰C)
