WHAT IS INFINITY FROM MARVIN'S
ULTREX FRAME MADE OF?
Ultrex is thin strands of strong glass cables, saturated with resins, and is pulled through a heated die. The glass cables ARE made from silica sand which is a safe and abundant natural resource. Ultrex has all the
characteristics that are crucial in Arizona’s extreme climate. It’s as strong as steel, rigid, essentially no thermal expansion, heat resistant, non-corrosive, and capped with a patented exterior coating that is resistant to fading and requires little to no maintenance. The finished frame is free from volatile organic compounds (VOC’s). Plastics use petroleum and other harmful chemicals in the manufacturing process.
