Varglas Silicone Rubber Sleeving
Varglas Silicone Rubber sleevings are produced by coating braided fiberglass with a high-performance silicone rubber that is extremely flexible and exhibits unusual toughness and abrasion resistance. In addition to having a Class 200°C rating, its brittle point of -73°C also suggests its use in a wide range of applications requiring resistance to temperature extremes.
( -73°C to +200°C) (-100°F to +392°F)
Dielectric Strength Grade(s): A-1 B-1 C-1
Varglas Silicone Rubber sleevings conforms to, and is listed on the Qualified Products List for, MIL-l-3190/6, latest revision (Grade A); NEMA TF-1, Type 5; and ASTM-D372.
Under the Component Program of Underwriters Laboratories, Grade A Varglas Silicone Rubber sleevings are recognized for 200°C, 600 volt service and complies with VW-1 flammability requirements under UL File #E63450 (VW-1 compliance of Grades B through C-3 is covered under UL File #E53690). CSA International certifies the use of Grade A for 200°C, 600 volt service and flammability requirements under CSA File #LR58486 VW-1. Varglas Silicone Rubber is incorporated in systems work, per UL Safety Standard 1446, to facilitate product acceptance by UL.
Varglas Silicone Rubber sleevings are in many applications like, appliances, motors, generators as well as in automotive, marine, aircraft electrical and electronic components such as transformers, coils, and relays to name a few. Silicone Rubber sleevings are best used where a 200°C thermal rating is required. In addition to being well-suited as heavy duty insulation when subjected to high heat, such as in die-casting and plastic molding, Varglas Silicone Rubber sleevings are also suitable for use in extremely low-temperature environments such as high altitude and aerospace applications.
