MATERIALS:Solvay Advanced Polymers LLC’s AvaSpire® AV-700 Series is a new line of modified PEEK grades that fill the cost/performance gap between high-performance crystalline polymers (PPS, LCP and high-temperature nylon) and PEEK, an ultra-performance crystalline polymer. These proprietary PEEK-based formulations - available in unfilled, filled and wear-resistant grades - offer comparable strength and modulus, equivalent or better chemical resistance and up to a 30 percent cost reduction versus comparable PEEK grades. Targeted uses include applications in automotive, heavy-duty off-highway equipment, oil and gas recovery, semiconductors and chemical processing. The flagship material is AvaSpire® AV-722 BG 20, an unfilled resin that is the basis for most of the AV-700 series formulations. The line also consists of AvaSpire® AV-722 CF30, a 30 percent carbon fiber-reinforced grade, and three wear-resistant grades (AV-742 SL30, AV-722 SL30 and AV-755 SL45). Another grade, 40 percent glass-filled AvaSpire® AV-750 GF40, has been previously available.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
