Coating adds heat shield for PPA resins.A new coating developed for polyphthalamide (PPA PPA 1. Palpation, Percussion & Ausculation 2. Pittsburgh pneumonia agent 3. Postpartum amenorrhea 4. Price per accession 5. Pure pulmonary atresia ) resins (also known as nylon 6T) provides a thermal barrier Noun 1. thermal barrier - a limit to high speed flight imposed by aerodynamic heating heat barrier limit, bound, boundary - the greatest possible degree of something; "what he did was beyond the bounds of acceptable behavior"; "to the limit of his ability" of up to 200 F to give the plastic added resistance to high-heat applications. Test plaques of Amodel PPA from Solvay Advanced Polymers, Alpharetta, Ga., were coated with a 4-mil layer of new IC-105 from Tech Line Coatings Inc., Murrieta, Calif., and then exposed to 600 F. After an extended time, the temperature of the plastic substrate was measured at only 400 F. This differential of 200[degrees] is said to add significant capability for PPA in auto under-hood applications such as turbocharger tur·bo·charg·er n. See turbosupercharger. tur  bo·charged adj. air-cooler housings. The proprietary coating reportedly eliminated oxidation of the PPA parts, which is expected to prevent degradation of properties such as tensile strength tensile strength Ratio of the maximum load a material can support without fracture when being stretched to the original area of a cross section of the material. When stresses less than the tensile strength are removed, a material completely or partially returns to its , elongation elongation, in astronomy, the angular distance between two points in the sky as measured from a third point. The elongation of a planet is usually measured as the angular distance from the sun to the planet as measured from the earth. , and stiffness. This opens up opportunities for PPA to replace aluminum or more costly polymers like PEEK. PPA parts can be coated by spraying or dipping and then air dried. Tech Line is exploring the use of its coatings with other plastics. Solvay. (800) 621-4557/PTDirect: 362NP * Tech Line: (951) 304-0498/PTDirect: 757NK |
