NU-SLEEVE SG-200 is a standard wall (NEMA TF-1, Table 3-1) coated
fiberglass sleeving made by applying a liquid silicone rubber to a fully annealed
fiberglass substrate. It is extremely resistant to abrasion, offers better coating
adhesion to the fiberglass compared to extruded rubber sleevings and has a high
heat/flex capacity. It is highly resistant to end fray and coating fracture, even
when stretched over rectangular conductors or wires larger than the normal
maximum inside diameter, making it an ideal choice for high stress applications
over a wide temperature range from -55°C to +200°C.
NU-SLEEVE SG-200 is highly resistant to inorganic acids and alkalis.
Chlorinated organic solvents and aromatic hydrocarbons will cause some
swelling and subsequent reduction in Tensile strength. Testing with ASTM #1 Oil,
a slight swelling was produced, while IRM #903 Oil will produce a higher volume
increase of up to 40%.
NU-SLEEVE SG-200 is used extensively in high temperature applications where
one or more of the following features are required: flexibility, expandability,
abrasion resistance, cut-through resistance and chemical resistance. It finds
application in terminal and lead insulation and protection, wire harness protection
in extreme environments as well as high current dry transformers. It may also be
stacked to obtain higher dielectric voltage ratings.
