Technical Polymers Chemical Processing Industry
 Arkema's technical polymers are used in a wide range of chemical industry applications.
Chemical Handling Systems
Kynar® Polyvinylidene Fluoride (PVDF) components are used extensively in the high purity semiconductor market (low extractible values), pulp and paper industry (chemically resistant to halogens and acids), nuclear waste processing (radiation and hot acid applications), and the general chemical processing industry (chemical and temperature applications). Kynar® PVDF fluoropolymers have also met specifications for the food and pharmaceutical processing industries.
Kynar Flex® resins are a series of PVDF-based fluoropolymers that are similar to Kynar® resins in purity and chemical resistance, but possess unique qualities of additional chemical compatibility in high pH solutions, increased impact strength at ambient and colder temperatures, and increased clarity.
Kynar® PVDF is fabricated into wide range of components including:
- Pipes, fitting and valves
- Pump assemblies
- Sheet and stock shapes
- Films
- Lined pipe
Rilsan® Polyamide 11 & 12 is extensively used in petrochemical, fuel handling and hydraulic applications. Rilsan® Polyamide 11 & 12 is a choice material in handling petroleum and natural gas application for both downstream and upstream operations. Rilsan® Polyamide has excellent resistance to chemical attack and permeation in petroleum and gas applications.
Rilsan® Polyamide 11 & 12 is available in many components including Pipes
Fittings
Vales
Lined pipe
Castor Oil Chemicals
Corrosion Control
Heptanoate salts act as stable anti-corrosion agents in hard water. The sodium salt gives efficient corrosion control at concentrations between 0.5 and 4.0 g/l. The protective coating effect can be used on copper, iron, aluminum and zinc.
The most effective mixture is obtained using a ratio of 10% sodium undecylenate (C7) and 90% sodium heptanoate (C11) salts.
Lubricants
The largest market for heptanoic acid is the production of neopolyol esters (NPEs) used as lubricants in military and commercial jet engines (JET LUB). NPEs are also used as lubricants in fluorocarbon based refrigerant systems (FRIGELUB).
NPEs result from the condensation reaction of heptanoic acid with a polyhydric alcohol such as neopentyl glycol, trimethylol propane (TMP) or pentaerythritol.
