SOLVAY
Modified PEEK range launched / Suits applications where standard PEEK over-specified
Solvay Advanced Polymers (Alpharetta, Georgia / USA; www.solvayadvancedpolymers.com) has introduced a new line of modified PEEK (polyether ether ketone) grades which it says offer a cost effective alternative to standard PEEK. The new “AvaSpire” AV-600 products “provide a cost-effective solution for high performance applications where PEEK is over specified”, says Jamal El-Hibri, senior research associate with the company.
Unfilled AvaSpire AV-600 grades have a 20% higher tensile elongation at yield than comparable PEEK grades and at least double the tensile elongation at break points, according to Solvay. This can benefit press-fit assemblies, and help manage the stress inherent in designs with unavoidable sharp corners.
The company says unfilled AV-600 grades also offer improved vertical flammability rating and higher stiffness between 150 °C and 190 °C than comparable PEEK material. The PEEK-based compounds have processing advantages over standard PEEK, including reduced warpage and improved ability to achieve tight dimensional tolerances, adds Solvay.
