ARKEMA to set new standards for PPA- based materials

February 21/2012

(arkema) -- Arkema has expanded its Rilsan  HT (high temperature) range with an ultra-flexible grade that is close to the flexibility of polyamide extrusion grades. Launched in 2009, Rilsan HT is the first flexible polyphthalamide (PPA)-based material to replace metal in high-temperature tubing applications.

With this breakthrough in ultra-flexibility, new opportunities for cost-effective alternatives to metal, rubber or fluorinated polymers in tubing assemblies are becoming a reality. With up to 70% renewable carbon content, Rilsan  HT aptly fits many industries' focus on environmentally sustainable solutions.

In the PPA material class known for its success as a metal substitute as well as its inherent brittleness and restriction to rather rigid injection-molded parts, the first flexible Rilsan HT grade with an 820 MPa modulus marks a significant step-change. This latest member of the Rilsan HT family now shifts the modulus boundaries even further downward, close to 500 MPa.
