Rilsan
Rilsan® polyamides offer a balance of critical thermal, chemical, and mechanical properties, such as high service temperatures, exceptional chemical resistance, and great impact strength.While Rilsan® may not be the elite performer in any one physical property individually; the combination of Rilsan® polyamides' exceptional properties overcomes the “downsides” that accompany many other engineering resins. Generally, it has a great resistance to high corrosion and abrasion. It can be applied to steel, cast irons or dural.

Polyamide 11 - Rilsan®
Rilsan® polyamide 11 is a high-performance technical polymer developed by Arkema in 1942. Derived from a series of complex chemical operations, Rilsan® PA 11 is one of the few polymers in existence produced from a 'green' raw material - castor beans.
Typical example of use is corrosion protection to piping systems, connecting members, elbow pipes or Y-pieces.
Rilsan® can be applied to new or renovated parts made of steel, alloys or dural.
