| Varglas Silicone Resin Sleeving & Varglas Silicone Resin 500 Sleeving |
Description
Varglas Silicone Resin 500 Sleeving is a Fiberglas® braid with a silicone composite coat ing. This sleeving is best in areas where design requirements specify superior moisture, flame and radiation resistance. In addition to its Class 200°C rating, it also exhibits good low temperature properties. Varglas Silicone Resin Sleeving is available as Silicone Resin 500 in the four top grades and as standard Silicone Resin in Grade C-3 with Silicone Resin 500 being a more flexible product designed to conform to sharp bends.
Specifications
Varglas Silicone
Resin 500 Sleeving conforms to, and is listed on the Qualified Products
List (QPL) for, MIL-l-3190/5, latest revision (Grade A); NEMA TF-1, Type
4; and ASTM-D372.
Under the Component Program of Underwriters
Laboratories, Grade A Varglas Silicone Resin 500 is recognized for 200°C,
600 volt service under UL File #E63450. It is incorporated in systems
work, per UL Safety Standard 1446, to facilitate product acceptance by UL.
The Canadian Standards Association certifies the use of Grade A Resin 500
for 200°C, 600 volt service under CSA File #LR-58486 “HFS”. Additionally,
standard Silicone Resin (Grade C-3) complies with UL’s VW-1 flammability
requirements under UL File #E53690.
Applications
Varglas Silicone
Resin 500 Sleeving is used in nuclear motors, electric motors, equipment
leads, relay leads and heating cable where flexibility, high dielectric
protection and heat endurance are required and temperatures up to 200°C
are encountered. Its good abrasion and radiation resistance also find wide
use in aerospace and atomic energy applications.

Packaging
Coils, spools or
36” lengths at manufacturer’s option, unless otherwise specified. There is
no cutting charge for 36” lengths, but lengths other than 36” are subject
to cutting charges.
Sizes over 1” l.D. are generally supplied in
36” lengths.
