An Extreme World Needs Extreme Materials
The flexible tubes used for the transportation of oil and gas are under enormous physical and chemical stress. With Kynar® polyvinylidene fluoride (PVDF) Rilsan® and Rilsan® Fine Powders biosourced polyamides (PA), the Arkema group provides a wide range of solutions to protect them against corrosion, chemical attacks and aging. These high performance polymers are also routinely used for coating pipes and flexible tubes in oil and gas installations. In these conditions, they are subject to extreme pressure and fluid constraints.
Review the Various Offshore Applications of Kynar® PVDF, Rilsan® Resins and Rilsan® Fine Powders
Offshore Seismic Acquisition
Rilsan® Polyamides have truly outstanding qualities for the harsh conditions that seismic acquisition cables operate in. 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 Rilsan® PA12
Choke & Kill Lines
Rilsan® PA11 and Kynar® PVDF chemical and temperature resistance properties allow for 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 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 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.

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 make 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.
Reinforced Thermoplastic Pipe
The light weight and flexibility of reinforced thermoplastic pipes made from Rilsan® PA11 and Kynar® PVDF allow for Oil & Gas customers to deliver the pipes in rolls, which allow for quicker and easier installations.
- Compatibility with aramid fibers
- Lower cost installation
- Resistance to harsh chemicals
- Resistance to high and low temperatures
