Connectors stand up to corrosion
ambient moisture and salts that could otherwise cause corrosion and product failure. Yet another benefit of these resins is their potential for flexibility. Special formulations of the resin remain flexible after curing. This is particularly helpful under conditions where thermal cycling is extreme...

Thermoset Composites
resistance than polyesters to solvents and alkalies, but less resistance to acids. Electrical properties, thermal stability (to 550 F in some formulations), and wear resistance are excellent. Phenolics, the oldest of the thermoset plastics, have excellent insulating properties and resistance...

Flouroplastics
and surface arc resistance of fluorocarbon resins are high and do not vary with temperature or thermal aging. Applications: PTFE resin applications can be classified in five categories: Fluid conveying systems -- gaskets, molded packings and seals, piston rings, and bellows. Static and dynamic load...

Next breakthrough material for military use could be carbon foam
The Army Space and Missile Defense Command, Huntsville, Ala., recently recruited Touchstone Research Laboratory Ltd., Triadelphia, W.V., to continue development of its carbon-foam technology. CFOAM's combination of mechanical and thermal properties, along with its ability to accept surface coatings...

Structural Foam
modulus of molded parts remains above 300,000 psi at service temperatures as high as 320T. Even after prolonged exposure to such temperatures, the resins do not discolor or degrade. Thermal stability and oxidation resistance are excellent at service temperatures well. Heat aging of the polymers...

Bonded films take the "bite"
Glass fibers poking out of plastic surfaces can abrade mating parts. Here's a way to stop it. A bonded film in cross section reveals the layered structure that forms the insulating barrier for GFTP parts. The substrate ( bluegray) is covered with nanosized reinforcement particles (pink) in a binder...

No Such Thing as Too Quiet
Sometimes proper selection and placement of insulating materials is part art, part science. Imagine a dishwasher so quiet you have to open the door to see if it's on. Or how about an automobile as quiet as a Rolex, a laser printer whose flashing LED is the only indication it's printing, or a vacuum...

Expanded PTFE Polymer Keeps Electrical and Electronics Cables Clean and Flexible
, and clean-room performance. Cable designers generally want materials that shield, jacket, and act as dielectrics to be inert, hydrophobic, and insulating. The materials also need to perform over a wide temperature range and withstand repeated and varied flexing. To determine material effectiveness...
