Review the Various Offshore Applications of Kynar® PVDF, Rilsan® Resins and Rilsan® Fine Powders
Choke & Kill Lines
In floating offshore operations, choke & kill lines are high pressure pipes connected to the subsea BOP (blowout preventer) stack that are used to control the pressure in the well. In some cases, the lines can run along the outside of the drilling riser to the surface. Rilsan® PA11 and Kynar® PVDF are often used as liners in these high-pressure piping systems.More Information
Wire and Cable
One of the primary uses of Kynar® PVDF for the oil and gas business is in the manufacture of offshore and downhole cables, which are primarily TEC (tube encapsulated cables) for “flat packs.” Kynar Flex® PVDF is ideal for the TEC application since it gives the wire and fiber optic cables the ability to withstand water permeation, abrasion, mechanical abuse, temperature extremes and corrosive chemicals over a lengthy service lifetime.More Information
Reinforced Thermoplastic Pipe
For over two decades, Rilsan® PA11 and Kynar® PVDF have been reinforced with Aramid fibers to produce reinforced thermoplastic pipes. The resulting products provide a light and flexible solution while still retaining resistance to harsh chemicals and high temperatures.More Information
Umbilicals are the critical link between the surface and underwater equipment such as the wellheads, subsea manifolds and ROV's. Because of its outstanding chemical resistance and durability, Rilsan® PA11 is used as the liner in umbilicals to transport hydraulic and injection fluids. Rilsan® PA11 is also used in the outer sheathing protecting the bundled tubes and cables. The unique offering of Rilsan® PA11 TLO provides an oligomer-free solution, which prevents the clogging of smaller pipes. Kynar Flex® Fluoropolymers can be used for more demanding conditions because of its resistance to harsh chemicals and higher temperatures, and its lower permeation properties.More Information
Rilsan® PA11 and Kynar® PVDF resins are the polymeric benchmarks for offshore flexible risers and flowlines. Thanks to its resistance to hydrocarbons and excellent combination of mechanical properties, Rilsan® PA11 has been used in the industry for over 40 years as a liner and sheathing material and has a lifetime prediction model published in API 17 TR 2. PA11 is also used as anti-wear tape in offshore flexibles. A proven material for over two decades, Kynar® is the ideal solution for more demanding conditions including harsh chemical contact and high temperatures. These materials can last up to 30 years in subsea operating conditions.More Information

Offshore Seismic Acquisition
Rilsan® Polyamides have truly outstanding qualities for the harsh conditions in which seismic acquisition cables operate. Rilsan® PA11 shows high dimensional stability and creep resistance, as well as tremendous resistance to seawater and strong abrasion resistance. In addition, its compatibility with other materials including fiber optics, extruded foams, and sensitive electronic equipment make it ideal for seismic acquisition applications.
Recommendations for Seismic Acquisition Cables:
- Flexible Rilsan® PA11 is the recommended solution for most offshore seismic acquisition cables
- Other solutions include Rilsamid® PA12 grades
Choke & Kill Lines
Rilsan® PA11, Kepstan® PEKK, and Kynar® PVDF chemical and heat resistance properties enable them to be used as liners in the high pressure lines used in offshore choke & kill systems.
For grade information contact an Arkema Technical Representative about PA11, PEKK and PVDF Heat Stabilized Extrusion Grade materials for Choke and Kill line applications.
When operating in harsh environments where maintenance can be very expensive, Oil and Gas companies require materials that can hold up to high temperatures and harsh chemicals. Rilsan® PA11, Kepstan® PEKK composites, and Kynar® PVDF have a high resistance to hydrocarbons and other blends of gasses/liquids and retain their dynamic properties while operating at high temperatures for up to 30 years.
Flexible Risers are subject to the extreme abuses of the ocean including varying temperatures, shifting tides, and harsh salt water. Rilsan® PA11. Kepstan® PEKK composites and Kynar® PVDF hold up extremely well given their inert nature which creates stability in their physical properties over long periods of time.
The low permeation found in Kynar® PVDF makes it an extremely useful material for offshore umbilicals. The resistance to multiple chemicals provides ease of process when creating umbilicals designed to be in contact with various fluids.
Wire and Cable
Kynar Flex® PVDF is an extreme material that can hold up to the demanding conditions that downhole wire & cables are subject to. Its resistance to harsh chemicals and heat makes it useable in numerous applications including electrical downhole cable, fiber optic downhole cable, and hybrid electric/fiber cable. Its compatibility with the many different types of materials, pressures, and temperatures make it a choice that brings ease of process when manufacturing and installing the cables.
Oil & Gas producers demand a product that can be relied on. With decades of trusted use in oil & gas wells around the world, Kynar Flex® PVDF is considered a preferred solution for downhole applications.
Seals and Backup Rings
With ultra-high mechanical properties, extreme temperature capabilities, and outstanding chemical inertness; Kepstan® PEKK is an ideal material for seals and backup rings in demanding oil and gas applications.
Kepstan® PEKK maintains an excellent compressive modulus even at elevated temperatures and offers excellent barrier properties against aggressive chemicals like H2S and Methane.
Powered by high performance 3D printing, Kepstan® PEKK can be 3D printed to form seals and other geometries for oil and gas applications as well, allowing for rapid production of parts on demand and more efficient use of material.
Reinforced Thermoplastic Pipe
The light weight and flexibility of reinforced thermoplastic pipes made from Rilsan® PA11, Kepstan® PEKK, and Kynar® PVDF allow for Oil & Gas customers to deliver the pipes in rolls, which allow for quicker and easier installations.
