Duron® MATERIALS

PTFE Polytetrafluoroethylene View More

Material NameMaterial DescriptionOperating Temperature Range (°F)Wear Resistance (1=Poor & 5=Excellent)Mating Metal Wear
DURON® 1 Premium-Grade Polytetrafluoroethylene (PTFE). This material has superior chemical resistance, resistance to weathering, low friction, low and high temperature capability, and electrical and thermal insulation. Color is white. -450 to 500 1 Low
DURON® 38 Modified Polytetrafluoroethylene has superior chemical resistance, low friction, low and high temperature capability, and electrical and thermal insulation properites. Duron® 38 has higher deformation resistance than Duron® 1. Material is white. -450 to 500 3 Low
DURON® 6 Polytetrafluoroethylene (PTFE) with proven Carbon-Graphite Fill has very good wear resistance, and high chemical compatability, in humid conditions and fluid applications. Color is black. -250 to 600 3 Low
DURON® 8 Polytetrafluoroethylene (PTFE) with a Proprietary Organic Fill has efficient wear characteristics along with low friction coefficients and can run dry at moderate surface speeds. This material is desirable for both bearing and sealing applications running on soft metal surfaces. Color is gold. -350 to 575 4 Low
DURON® 9 Polytetrafluoroethylene (PTFE) with a Proven Inorganic Filler is self-lubricating and provides excellent friction resistance and wear properties. This material has one of the lowest metal-mating wear characteristics of all our filled PTFE materials. Color is tan. -450 to 550 3 Low
DURON® 59 Polytetrafluoroethylene (PTFE) with a Proprietary Fill is best used in high PV and high temperature applications, and has excellent corrosion resistance. Color is black. -300 to 600 3 Low
DURON® 67 Modified Polytetrafluoroethylene with Premium Organic Fill has better compressive strength than Duron® 8. Color is orange. -400 to 550 4 Low
DURON® 85 Modified Polytetrafluoroethylene with Carbon-Graphite Fill is best used where a low friction seal is required or where temperature of chemical extremes are encountered. Color is black. -300 to 500 3 Low
DURON® 96 Polytetrafluoroethylene (PTFE) is a material that has efficient wear resistance and large tolerance to permanent deformation under loading. Duron® 96 has excellent chemical compatibility with a wide range of fluids. Color is black. -320 to 500 2 Low
DURON® 4 Polytetrafluoroethylene (PTFE) with Mineral Fill. This material has greater wear and extrusion resistance than Virgin PTFE. Material is FDA approved. Color is off white. -250 to 500 4 High
DURON® 5 Polytetrafluoroethylene (PTFE) with Graphite Fill has very good wear resistance, and high chemical compatability, in humid conditions and fluid applications. Similar to Duron® 6 with more fill. Color is black. -300 to 575 2 Low
DURON® 11 Polytetrafluoroethylene (PTFE) with Glass Fill. Duron® 11 shares the same chemical compatability benefits as Duron® 1 with much higher wear and pressure tolerances and is an appropriate material for bearing and sealing applications. The wear on the shaft or dynamic bore should be considered. Color is grey. -320 to 475 4 High
DURON® 134 Polytetrafluoroethylene (PTFE) with Carbon-Graphite Fill is a choice material often used in aqueous fluid media at high temperatures. Color is black. -250 to 600 4 Low
DURON® 510 Polytetrafluoroethylene (PTFE) with Carbon-Graphite, and other Premium Fillers has excellent wear characteristics with low coefficients of friction. This is one of our best wear materials used for rotary and high speed reciprocating applications. Color is black. -400 to 550 4 Medium

UHMW Polyethylene View More

Material NameMaterial DescriptionOperating Temperature Range (°F)Wear Resistance (1=Poor & 5=Excellent)Mating Metal Wear
DURON® 15 Extruded Ultra-High Molecular-Weight Polyethylene (UHMWPE) is similar to Duron® 14 for general application use for high pressure and demanding wear applications. Material is clear. -350 to 180 5 Medium
DURON® 138 Ultra-High Molecular-Weight Polyethylene (UHMWPE) Reduces the oxidization rate of the material at higher temperatures thereby slowing material degradation and extending wear-life in chemical applications. Color is white. -350 to 250 5 Medium
DURON® 155 Molded Ultra-high-molecular-weight polyethylene (UHMWPE) Well-suited for sealing small molecular gases or liquids. The material is FDA approved. Material is clear. -350 to 180 5 Medium
DURON® 14 Premium Ultra-High Molecular-Weight Polyethylene (UHMWPE) with a Gold Filler has superior wear and pressure tolerances, but does not have the same high-temperature tolerance as PTFE materials like Duron® 1. Duron® 14 is a choice material for dynamic high-pressure applications where low wear is required. Color is gold. -350 to 200 5 Medium

PEEK Polyetheretherketone View More

Material NameMaterial DescriptionOperating Temperature Range (°F)Wear Resistance (1=Poor & 5=Excellent)Mating Metal Wear
DURON® 19 Injection-Molded Polyetheretherketone (PEEK) is a high-modulus material with an excellent tolerance for high temperatures. Highly recommended for backup rings. Color is tan. -200 to 480 4 Medium
DURON® 50 Polyetheretherketone (PEEK) a high-perfomance engineered thermoplastic material, is used where a high modulus polymer is required to resist high pressure or loads. Material is FDA approved. Color is grey. -350 to 250 4 Medium
DURON® 62 Extruded Polyetheretherketone (PEEK) is typically used as anti-extrusion or backup-ring material because of its relatively low elongation and high stiffness. Material is FDA approved. Color is tan. -350 to 250 4 Medium
DURON® 150 Bearing-Grade Polyetheretherketone (PEEK) is a premium material for bearing applications where traditional metal ball bearings cannot be used. Duron® 150 has a very high temperature tolerance. Color is black. -350 to 250 5 Medium
