Voltalef® 302 Polychlorotrifluoroethylene Arkema High Performance Polymers
VOLTALEF 302 resin is a fluorinated polymer which presents an exceptional behavior at very low temperatures. It is usable in continuation from -200°C to +150°C with allowable peaks at 200°C. It is non-inflammability, has excellent chemical and radiation resistance, good barrier properties, is insensitivity to oxygen and water with good electrical properties. The processing is critical but can be done by extrusion, injection and compression molding.
Voltalef 302Voltalef® 302, also known as PCTFE, belongs to the family of fluoropolymers and is used in the manufacture of products for sealing and cryogenic applications. The outstanding properties of Voltalef
Voltalef® PCTFE is a brand of the French chemical group ARKEMA. It is a group that works specifically in performance materials and more particularly in specialty chemicals. Voltalef® PCTFE products have been created and sold by this group for over 40 years. Like all PCTFEs, Voltalef® products have exceptional properties compared to PTFE (Teflon®). They are especially appreciated in many sectors due to their thermal resistance:
* a temperature range between -255 °C and 150 °C
* high mechanical strength compared to PTFE, especially when used in compression with very low creep
* a good density, a low rate of deformation, thus extremely resistant to compression and shock,
* a flammability rate close to zero,
* good chemical inertia: Voltalef® is resistant to most mineral and organic reagents,
* good resistance to UV and X-ray radiation
* a very low temperature permeability to liquids, humidity and gases.

ARKEMA currently produces several types of Voltalef® : Voltalef® telomers, presented in the form of fats and oils (Voltalef® 300 series) or Voltalef® in the form of granules and powder, intended for compression and extrusion processes (Voltalef® 302 and Voltalef® 402).
Voltalef® provides high performance products for various applications
Voltalef® 302 can be processed and machined in several ways: * Compression molding produces parts with excellent mechanical and chemical properties because of the slow and homogeneous cooling process,
* Extrusion allows to obtain longer rods (2 meters in standard and up to 3 meters). Extrusion is done with a diameter of 8 to 20 mm.Thanks to these processes, Voltalef® can be used to manufacture reliable, high-performance products for critical sectors such as cryogenics, chemical engineering, the military, electricity, aerospace and aeronautics, as well as in the medical sector.
