FINALLY, A KYNAR® GRADE FOR SEALS, O-RINGS, AND DIAPHRAGMS

Kynar UltraFlex™ is an elastomeric material based on Arkema's proven PVDF (polyvinylidene fluoride) resin. This unique fluoropolymer exhibits exceptional resistance to chemicals, ozone, ultraviolet light, radiation and moisture. Molding is very similar to many fluoroelastomers without the use of curing agents and molding time is significantly reduced. Post-curing of molded parts improves mechanical properties and chemical resistance.

PVDF Elastomers

• Clear Elastomeric Fluoropolymer
• Not Affected by UV or Radiation
• Weatherable
• Water Repellent
• Broad Chemical Resistance
• No Curing or Cross-Linking Agents
• No Shelf Life for Feed Stock

KYNAR ULTRAFLEX™ Elastomer is a clear elastomeric fluoropolymer that resists chemicals, ozone. UV rays, radiation and moisture.

A unique new technology creates open-celled construction foams that exhibit most of the known properties of Arkema's KYNAR® polyvinylidene fluoride (PVDF) fluoropolymer without the use of blowing agents or melt processing. This method allows the creation of foams with substrates that would otherwise be sensitive to heat or chemicals used in other foaming methods. This composite technology creates properties that are not inherent in open-cell construction polymers.

PVDF Foam & Foam Composites

• Viscoelastic Properties
• Open-Cell Construction
• Breathable
• Does Not Support Combustion
• Chemically Stable to 250ºC
• Heat Resistant
• Uniform Cell Sizing
• 70 - 90% Free Volume Spacing
• Fillers Create Composite Structure
• Transparent to UV Radiation
• Weatherable and Water Repellent
• Thermoformable

KYNAR ULTRAFLEX™ foam can be molded or thermoformed into a wide variety of shapes, thicknesses.

Open-cell structure allows for moisture vapor transmission and hydrostatic pressure resistance. Pore size can be adjusted with foam density.

Glass encapsulated in PVDF ULTRAFLEX™ resists bum-through by a propane torch longer than a 1/8" aluminum sheet, while exhibiting virtually no flame or smoke generation.
