Atofina has developed a new conductive polyamide

Atofina has developed a new conductive polyamide. Risan® M-BESN P 212 CTL has been specifically developed for the automotive market. The new Risan 11 polyamide material is claimed to fulfill the requirements of fuel systems specified by the automotive industry SAE J2260, while providing the properties of polyamide 11.

The company says that it is the world's first polyamide 11 to meet the conductivity requirements of US carmakers - surface resistivity below 106 Ohms. Other properties include good resistance to hydrocarbons and alcohols for long fuel system life, as well as good mechanical strength. This includes resistance to vibration, pressure and abrasion, which eliminates the need for any reinforcement. It offers good low temperature properties, down to -40°C, which ensures ideal fitting tightness at low temperatures, as well as improved impact resistance.

According to Atofina, the new PA 11 has a higher melting point than conductive PA12. It also offers improved mechanical resistance, including burst pressure and connection fitting retention, at high temperatures. It also offers good flexibility making the end product (the tube) even easier to fit and therefore significantly optimizing its installation.

Used in monolayer and in two-layer structures (with standard PA11), Risan® M-BESN Black P 212 CTL is primarily processed by extrusion for the manufacture of both corrugated and smooth tubing. Atofina adds that pipes made from Risan 11 are suitable for automotive fuel storage and delivery systems.
