A Targets have a retro-reflective reflector on a circular KAPTON® backing with a 0.002″ SILICONE pressure sensitive adhesive (psa). The A-250 Targets (pictured above) withstand a thermal cycle of ± 300°F.
AA Targets have the same KAPTON® backing as the A Targets. The A denotes an ACRYLIC PSA is used for this series of targets. The advantage of the Acrylic psa we use is that it will pass the NASA out gassing test. The ACRYLIC PSA we use is listed on the NASA Data for accepted out gassing Adhesives.
Retroreflectors are available from 3/16″ through 1″ in size.
Metric retroreflectors are available from 3 mm through 25 mm.
To designate the retroreflective material that allows the target to function at 500°F add an “H” (i.e. A becomesAH and AA becomes AAH).
