PRODUCT SPECIFICATIONS:
Description: Material is RoHS compliant (European Union directive 2002/95/EC).
GMUHS31 is a crosslinked, flexible, heat shrinkable thermal transfer and dot
matrix printable polyolefin. This product meets the material requirements
and physical properties of AMS-DTL-23053/5C (Class 1 and Class 3) and
UL standard 224 with a VW-1 rating. When printed using RMH4BL,
RMEH4BL, RHH4BL-S, RMR4BL, RMER4BL, RMR4WH, RHR4BL-S,
or RMR2BL thermal transfer ribbons it will also meet SAE-AS5942, MIL-
STD-883F Method 2015.13, Solutions A, B and D, and MIL-STD-202G
Method 215K, Solutions A,C and D. This product has been tested for use as
an identification marker for use in (Class 1E) harsh environments in various
nuclear power plants.
