Custom Filled-Type Fluoropolymer Compound

Custom Filled-Type Fluoropolymer Compound

Always ready for your unique material needs

What can we do for you?

  • When the standard polymer formulation does not meet the requirements of your unique application, you can customize the formulation to create innovative fluoropolymer compounds with specific properties that the base polymer does not have. Through our mature customized facilities, fluoropolymer compounds can be made to have enhanced performance compared with base polymers, such as reducing weight, improving dimensional stability or abrasion resistance, etc.
  • Commonly used fillers for custom PTFE composite materials include those listed in Table 1. Of course, if you need to customize other basic fluoropolymer composite materials, such as FEP, PVDF, ETFE, PFA, etc., please contact us to discuss your detailed requirements.
  • When you choose our custom polymer compounding service, you will get a fast turnaround of a wide range of custom polymer compounds, from prototypes and small batches to production-scale quantities.

Table 1. Fillers and characteristics

FillersCharacteristics fillers impart to the materials
  • Good wear resistance
  • Low creep
  • Good compressive strength
  • Excellent chemical compatibility
  • Glass-filled PTFE compounds are abrasive to mating surfaces
Molybdenum disulfide (MoS2)
  • Improving wear resistance
  • Lowering the coefficient of friction
  • Typically combined with other fillers (such as glass and bronze)
Carbon (powder or fiber)
  • Excellent compression (low deformation under load)
  • Excellent wear resistance
  • Good thermal conductivity (heat dissipation)
  • Low permeability
  • Excellent lubricity
  • Decreased wear
Bronze (a copper-tin alloy)
  • Excellent wear resistance
  • Excellent thermal conductivity
  • Higher friction than other filled PTFE compounds
  • Poorer chemical resistance than other PTFE compounds
Stainless steel
  • High wear resistance
  • High load bearing capability
  • Better chemical resistance than bronze-filled PTFE
Wollastonite (calcium silicate)
  • Properties similar to glass (minus the abrasiveness)
PPS (polyphenylene sulfide)
  • Improving wear and abrasion properties
  • Excellent deformation
  • Excellent extrusion resistance
  • Offering superior wear and abrasion resistance
  • Lower friction properties
  • Will not abrade mating surfaces even for soft materials
