Kynar® is the registered trademark of Arkema Inc.'s polyvinylidene fluoride (PVDF) resin.
PVDF is a fluorinated polymer, or fluoropolymer, that is dissolved, dispersed, foamed, and melt processed
for use in a wide range of industrial and architectural applications.

| Where is Kynar® PVDF used? |
Kynar® PVDF resins are used in the power, renewable energies and chemical processing industries for their
excellent resistance to temperature, harsh chemicals and nuclear radiation, in the pharmaceutical, food & beverage
and semiconductor industries for their high purity and availability in a multitude of forms, in the mining and metal
preparation industries for their resistance to hot acids of a wide range of concentrations, and in the automotive and
architectural markets for their chemical resistance, excellent weatherability and resistance to UV degradation.

| What is the chemical resistance of Kynar® PVDF? |
Kynar® PVDF components are resistant to some chemicals up to 300°F (149°C), depending on the pH. The Kynar® PVDF
Chemical Resistance Brochure lists hundreds of chemicals, their concentration, and the highest recommended operating temperature
for Kynar® PVDF components in contact with them. Arkema has documented case histories of Kynar® PVDF based on over
25 years service in chemical applications.

| Why is Kynar® PVDF a preferred polymer and material of construction for high purity components used in semiconductor and pharmaceutical applications? |
Components formed from pure Kynar® and Kynar Flex® resins do not produce particulate contaminants. Kynar® resins are 100%
pure fluoropolymer and require no further additives in processing.

-
| How does the price of a Kynar® PVDF system compare to that of a stainless steel system? |
Kynar® PVDF systems have installed costs comparable to stainless steel systems.

-
| What is the regulatory status of Kynar® PVDF resins? |
Certain Kynar® resins meet USDA, 3-A, USP Class VI, NSF 51 NSF 61, and CRC Kosher listings. Specific grades of Kynar® PVDF also meet
several flame and smoke codes such as FM4910,
UL 723 and ASTM E 84 (25/50),
UL 94 (V0),
ULC S102.2, ASTM E 162, ASTM E 662,
NFPA 262 and others.

-
| Is special equipment needed to process Kynar® PVDF? |
Kynar® PVDF is processed at relatively low temperatures compared to other fluoropolymers. The same tooling used for polyolefins,
PVC, or nylon can be used to injection mold or extrude Kynar® PVDF. Arkema does recommend chrome or nickel plating of the screws and equipment.

-
| What component forms are available in Kynar® and Kynar Flex® PVDF resins? |
Kynar® PVDF components can be found in a complete line of fluid handling products including solid and lined pipe, vessel linings, coated metal, pumps,
valves, tower packing, sheet and rod, nozzles, films, flexible tubing, microporous membranes and monofilament fabrics.
