These products meet all of the requirements of ASTM D5213 which
superseded MIL-P-46112B.
TH Series polyimide films exceed UL 94 V-0 flammability, as
well as a 455° (235°) Relative Thermal Index
(RTI) for both electrical and mechanical properties (UL file E231847).
These high performance films are exclusively manufactured to exacting
specifications for the electrical insulation market by Taimide
Technology, Inc. (Taiwan).
Roll lengths can be customized, but the standard is 5000 feet (1524m)
for TH-025 1.0 mil film and 2500 feet (762m) for TH-050 2.0 mil film.
Rolls can be StablEdge® wound as well as flat pads or
universal packages. Consult customer service for details.
Width tolerances on slit materials will be held to 1/64" (0.4mm) up to
the max width of 61.8" (1570mm).
Splices are possible with slit width orders. They will be held to a
minimum, if they occur. Minimum length between splices will be 300 feet
(91m).
