Plastics and Elastomer Compatibility
Product Information
Krytox™ perfluoropolyether (PFPE) oils and greases
thickened with polytetrafluoroethylene (PTFE) are agreat choice for nonmetallic components.

Following is a partial list of plastics and elastomers known to havebeen used with Krytox™ lubricants:
ABS

Nylon 6,6

Krytox oils and greases have been used as plastic or elastomer
lubricants for over 40 years. Krytox™ PFPE oils and greases andFluoroguard™ PFPE compounding additives are used as lubricants
for nonmetallic materials in automotive, aerospace, and industrial
applications for seals, gears, squeak elimination, and other critical uses.

Acetal – Homopolymer and Copolymer

Nylon 12Aramids

PEBA

Buna NPEEK

Butyl 325

Polyamides

Chlorosulfonated Polyethylene

Polycarbonate

Krytox™ oils and greases are inert and do not react with elastomers
or plastics. These oils and greases will not cause elastomers orplastics to swell, shrink, or crack. Krytox™ lubricants do not hurt theperformance of the elastomer, nor improve the upper temperaturecapabilities of the material—the thermal stability of the elastomeror plastic itself constitutes any limitation.

Delrin® Acetal

EPDM

EPT, Peroxide Cure

Polypropylene

Ethylacrylate

PTFE Fluorocarbon

FEP

PVC

Fluoroelastomers

Fluorosilicone

SEBS

HDPE

Silicone

HNBR

Styrene Ethylene Butylene Polymer™

Krytox™ greases thickened with PTFE are equally non-reactivewith polymers. Some types of grease that are used for lubricating
metal bearings have additives for anti-corrosion and extreme
pressure metal-to-metal contact, and they can affect some typesof seal materials at higher temperatures. For high temperatureapplications, Chemours usually recommends additive-free oils andgreases for lubrication of plastics and elastomers.

Hydrocarbon Rubber

Styrenic Polymer

Hypalon® Synthetic Rubber

Teflon™ Fluorocarbon

Hytrel® Polyester Elastomer

Thermoplastic Polyurethane

Krytox™ performance lubricants are resistant to oxygen and reactive
gases, and are inert to virtually all chemicals that are commonly usedin chemical processing and plastics manufacturing.

LDPE

Thermoset Polymers

Methyl Silicone

Thermoplastic Rubber

Natural Rubber

TPE

Most plastic materials contain other ingredients in addition to thespecific plastic component. These include coloring agents, fillers,modifiers, anti-wear additives, and other ingredients to make thepolymer work better under specific conditions. Because of thenon-reactivity of Krytox™ lubricants and the many possible productcombinations, Chemours does not test individual formulations forcompatibility.

NBR

TPU

Neoprene WRTUrethane

NitrileVamac® Ethylene Acrylic Elastomers

Nylon

Viton™ A and B Fluoroelastomers
Zytel® Nylon

Nylon 6For higher temperature use with Kalrez perfluoroelastomer, the user should ask forguidance on the proper grades.
