Description

The new 7.5 µm Kapton® thin - film available from Chemplex exhibits similar properties as the previous traditionally used type: 7.5 µm gauge, high sample retention tensile strength, equivalent % Transmittance values of x - rays, chemical resistance and melting points. The difference between the previous Kapton film and the new Chemplex® 7.5 µm Kapton® thin - film is “it is not subject to the U.S. International Traffic in Arms Regulations (ITAR).” Reportedly, an unknown slight difference between the ITAR controlled and the new 7.5 µm Kapton® thin - film may affect the reliance on previously established calibration data. Chemplex® suggests judiciously re - examining this issue for verification prior to implementing an analytical program. Kapton® is limited in availability only in SpectroMembrane®® Carrier Frames.
