SPEEDBOARD™ C prepreg is comprised of expanded polytetrafluoroethylene (ePTFE) that has been impregnated with a modified BT resin. The air space inside the ePTFE is replaced with resin and the ePTFE becomes the carrier for the resin. Eventually, the resin flows, fills, and bonds during the lamination process in the same manner as glass-based thermoset prepreg. The conformable ePTFE toughens the dielectric, enabling surface planarization for high-density fine lines and spaces.

Machinable glass ceramic can be produced in sizes up to 20 inches and is readily machinable on conventional equipment with standard cutting tools. Rescor 914 is dense and vacuum tight, inert to oxidizing and reducing atmospheres, and has low thermal conductivity. With a maximum operating temperature of 1,000F, it can be utilized in such applications as electrical insulation, furnace components, and RF heating fixtures.

Bin activators for material handling have been redesigned and improved to include a number of new features and models. Design changes include a new vibrator assembly, sanitary design, and variable rate, while smaller units (less than 6 ft) now offer a vibrator which is more economical than past units. The line has also been expanded to include a new series of bin dischargers.
