Chemical Processing Industry (CPI)

Kynar® PVDF solutions for high purity and highly chemically resistant pipes, fittings and components.

A UNIQUE POLYMER RANGE THAT CAN REPLACE STAINLESS STEEL IN SOME OF THE WORLD'S MOST EXTREME MATERIAL APPLICATIONS

Kynar® PVDF - a Standout Fluoropolymer for CPI

When it comes to the most demanding applications in the chemical process industry, fluoropolymers are famous for their tremendous chemical resistance and overall durability. Kynar® PVDF has the best balance of mechanical properties and melt processability among all the fluoropolymers. Semi-rigid, flexible and highly flexible grades are available.

Typical Applications

Design engineers all over the world know it by name - Kynar® PVDF. The brand is synonymous with quality, purity and performance.

 

Typical applications include stock shapes (machinable rods and sheets), tubing, molding, piping, tower packing, filters and compounds for many of the following.

 

  • Pulp and paper processing - resistant to common bleaching agents
  • Metal preparation - resistant to high temperature acids
  • Petrochemicals - resistant to alkylation acids and hydrocarbon mixtures
  • Food and beverage - FDA listing, resistant to steam cleaning and acidic foods
  • Waste water treatment - resistant to chemical mixtures, outdoor exposure, halogenated cleaning agents
  • Pesticides - resistant to halogenated solvents; low permeation
  • General chemical processing - resistant to a wide range of pH exposures pH<1 to 13.5
  • Semi-conductor manufacture - very high purity water, resistant to acids and ozone
  • Pharmaceutical / Biotech - resistant to ozone and steam sterilization, FDA compliant, resistant to a wide array of acids
  • Plenum pipe - resistant to acid waste drainage
  • Nuclear waste processing - resistant to repeated radiation exposure and hot acid washes
  • Chemically resistant powder coatings

The high heat resistance, low permeability and high mechanical strength of Kynar® PVDF makes it a strong candidate for the production, storage and transfer of highly corrosive fluids.

Focus On: Tower Packing

Arkema offers a wide variety of fluoropolymer grades under the names Kynar® and Kynar Flex® that are readily injection moldable and can be considered as tower packing materials.

 

Tower packing and mist eliminators made with Kynar® PVDF are readily available in several types of configurations for use in distillation and scrubbing columns. Kynar® PVDF is easily injection moldable and can fill even the most intricate dump tower packing molds.

 

Listed below are benefits specific to Kynar® PVDF, a polymer very commonly used in the pulp and paper, mining, petrochemical, semiconductor, pharmaceutical, chlorine caustic, and general chemical industries.

 

Benefits:

  • Temperature Rating up to150°C continuous
  • Highly chemical resistant to strong acids, chlorine, bromine and hydrocarbon mixtures
  • High compressive strength
  • FDA, USP Class 6, NSF compliant
  • Able to process without additives for purity applications

 

Product Availability:

  • Kynar® Homopolymers for high temperature applications
  • Kynar® Copolymers for high pH chemical exposure
  • Kynar® UHM reinforced with glass fibers for high heat deflection and superior strength
