  • What is the Difference Between Carbon Paper and Carbon Cloth Based Gas Diffusion Layers (GDL)?
    Carbon Paper Gas Diffusion Layers (GDL) (e.g. Sigracet, Freudenberg, Toray, etc) tend to be thinner and more brittle than Carbon Cloth Gas Diffusion Layers (e.g. ELATâ ¢, GDL-CT). Â Each type has a different mass transport, porosity, hydrophobicity, and conductivity. Â. Papers such as Toray
  • SmartMoves TM Spotlights: CNC Machines (.pdf)
    There's no question that water sustains life. It also helps shape it. For instance, when water is concentrated into a highpressure stream shot from a waterjet at 60,000 psi, it can cut and shape a wide array of materials ranging from cloth and foam to glass, plastic and rubber as fast as 100 ft
  • Medical Device Link . Filter Technology Separating the Good from the Bad
    need to be thick and fashioned from materials such as asbestos, glass fiber sheets, cloth, and paper. Surface filters trap particles at the top of the matrix as the fluid flows easily through. Membrane filters can almost always be classified as surface filters. One common filter membrane
  • Medical Device Link .
    in the 1950s, it was the introduction of polyimides in the 1960s that made significant contributions to meeting exacting industry demands. In 1961 DuPont introduced film (under the trade name Kapton) and varnishes for electrical applications and wire insulation. Subsequently moulding powders, laminating
    . Use a soft cloth or damp paper towel. Abrasive material,. such as scrubbers, will scratch the surface. The following brand name cleaners have been found. to work well with polypropylene materials. Fantastik household cleaner. Glass Plus cleaner. Formula 409 household cleaner. LPS Resolve Cleaner
  • Medical Device Link .
    , office automation equipment, and consumer electronics. Whereas most people use a bare finger to activate a touch screen, medical personnel are frequently required to wear gloves. Common capacitive touch screens do not respond to a touch obscured by cloth, plastic, or other nonconductive materials
  • Pulp and Paper: Improve Employee Health with Dust Control (Part 1)
    hazardous dust from becoming airborne. A multi-stage system allows debris to pass through several steps of filtration such as a paper bag, main cloth filter and HEPA filter, with each level acting as a barrier to the next. By the time the particles reach the last stage, the majority of the debris
  • What is the Purpose of a Gas Diffusion Layer (GDL)?
    separately from the Membrane or MEA.  Acting as an electrode is the easy part of the GDL/GDE, though. What Does a Gas Diffusion Layer (GDL) Consist Of?. The GDL is a porous structure made by weaving carbon fibers into a carbon cloth (e.g. GDL-CT and ELAT) or by pressing carbon fibers together

    , and consumer electronics. Most people use a bare finger to activate the touch interface of screens they encounter in the world. But in the medical field, personnel are frequently required to wear gloves. Common capacitive touch screens do not respond to a touch obscured by cloth, plastic, or other
