• Where Reticulated Polyurethane Foam's a Fit
  to meet CAL-117 fire protection standards. They are inherently impervious to breakdown from microbial organisms and can be manufactured with permanent fungicidal/bactericidal additives to help control microbial activity. In addition to use as sealants or gaskets, reticulated polyurethane foams can...
• Tight seals for the long haul
  , gaskets seal the cover and housing to protect electrical contacts inside. If gasketing materials take a permanent set over time, they lose the ability to press against the cover and flange and make a tight seal. Motor housings often need additional watertight seals to plug access holes. Roof-mounted...
• MAKE YOUR MARK with the Power of Hot Light
  Industries are searching for environmental friendly, fast and reliable, task flexible marking systems which are capable of direct part marking on a variety of materials with high quality and permanent marks for traceability. ./44446c76-c6c3-4113-8512-649f6aaa8e55 LaserStar Marking Systems...
• MICRO:Product Technology News (Oct '99)
  ). The pump also synchronizes automatically with the manufacturer's other PLCs, and its software integrates fully with the company's pump monitoring system, which has microprocessor control and an adjustable threshold for warnings and alarms. A permanent measurement display shows exhaust pressure...
• Specifying elastomer footpads
  the recess when compressed. The Poron cellular urethanes don't take a permanent compression set under load and retain over 90% of their original thickness when tested under ASTM D3574 guidelines at room temperature. It is important to note however, that compression set test methods for foams don't...
• PSAs take hold
  or carrier, sometimes with different adhesive types. For example, one carrier side may contain a permanent adhesive while the other side uses a removable formulation. Like roll-form transfer films, roll-form, double-coated tapes typically employ one release liner while sheets use two. Double-coated tapes...
• I want my MVT
  . And in this respect also the absence of noise and smell are relevant. To fulfill these requirements a film should be formulated with a low modulus and coefficient of friction value, and low permanent set after stain. IT'S ALL IN THE CHEMISTRY. A number of properties affect the permeability or breathability...
• Plastic Nuts become a hot topic
  as the point at which frictional heat causes permanent deformation of the plastic. Torlon polyamide-imide and Vespel polyimide engineering plastics, for example, have PV limits five to 10 times that of acetals. Both can be compounded with lubricants, though their high melting temperatures make them...
• HOW TO SELECT THE IDEAL ENCLOSURE GASKET
  . Testers then strike the materials with a 16-ounce hammer and measure. Tensile and Elongation Test. it to determine the compression, as well as any permanent impact points. Compression. testing is not required by UL, but the American Society for Testing and Materials (ASTM). provides standards...
• Oil-Resistant Rubbers
  , good resilience, low permanent set, and good abrasion resistance. Tear resistance is inferior to that of natural rubber, and electrical insulation is lower. NBR is used instead of natural rubber where increased resistance to petroleum oils, gasoline, or aromatic hydrocarbons is required. Uses of NBR...
