RT-375
Very clear, thin-wall, flexible,
fluoropolymer heat-shrinkable tubing
RT-375 is a highly flame-resistant,
heat-shrinkable, thin-wall tubing
that has excellent clarity. It is
manufactured from a modified
fluoropolymer whose properties
include toughness, chemical
resistance, and high-temperature
performance.
A very thin wall gives RT-375
excellent flexibility.
Applications include protection of
wire and cable markers subject to
abuse; bundling and jacketing of
wires and cables to protect them
from mechanical and chemical abuse
while permitting full inspectability of
the item covered; and protection of
electronic components without losing
the ability to identify the part.
RT-375 is UL-recognized and
CSA-certified at 150°C, 600 V,
with a VW-1 flame-retardancy rating.
Temperature rating
Full recovery temperature:
150°C
Continuous operating temperature:
–55°C to 150°C
