UL94 includes 12 flame classifications based on the results of small-scale flame tests. The Meldin® 7001 grade is incorporated into the six classifications where materials are commonly used in manufacturing enclosures, structural parts and insulators and has been UL listed with a “Plastic Recognition Yellow Card” (5VA and V-0). The UL Yellow Card denotes the material color and bears information relative to specific polymeric materials which a company has submitted to UL to be tested, and representative samples of the product have been evaluated by UL and meet their published and nationally recognized standards for safety. The listings (for plastic materials) are published in the "UL Recognized Components Directory," Volume II, Section QMFZ2, under the heading “Plastics.”
UL testing is important and valuable to end users of the material so they can determine the suitability of specific applications as well as save time and cost by eliminating the need for additional testing. As part of the Seals Group’s annual safety standards and material diligence testing, their Meldin® manufacturing site in Bristol, Rhode Island, is audited by a UL representative followed by material testing at their lab per UL94 requirements. Their other grades, Meldin® 7021, 7022, and 7211 (filled polyimides), have also passed UL94 testing with V-0 and 5VA ratings. Aside from being UL94 flammability listed, the Meldin® 7000 series have been qualified for numerous industry-specific as well as customer-specific specifications.
The Meldin® 7000 product line will be featured at the K Trade Fair 2013 (http://www.seals.saint-
