Most silicone rubber is characterized, chiefly, by its capability of performing satisfactorily at elevated temperatures. Varglas ES-4400 Silicone Rubber, in addition to providing superior dielectric and thermal protection, at less weight, was developed to meet unusual fluid and flame resistance requirements. Its high temperature performance places it in a 220°C classification. Specifications Varglas ES-4400 Silicone Rubber Sleeving conforms to, and is listed on the Qualified Products List (QPL) for, MIL-l-3190/8, latest revision (Grade A). It also exceeds the requirements of NEMA TF-1, Type 5; and ASTM-D372. Under the Component Program of Underwriters Laboratories, Grade A Varglas ES-4400 Silicone Rubber is 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-1 is covered under UL File #E53690.) CSA International certified the use of Grade A for 200°C, 600 volt service and flammability requirements under CSA File #LR58486 VW-1/FT1. Varglas ES-4400 is incorporated in systems work, per UL Safety Standard 1446, to facilitate product acceptance by UL. Applications Varglas ES-4400 Silicone Rubber Sleeving’s superior dielectric strength, high and low temperature performance, and excellent fluid and flame resistance make it ideally suited for use in industrial instrumentation for measurement, analysis and control; surgical, medical and optical instruments and apparatus; electrical and electronic machinery and equipment; and aircraft and other transportation equipment where its lighter weight provides an additional performance advantage. Sizes AWG #24 through 2” l.D. Other sizes subject to inquiry. Standard Color Blue-gray and tan. Other colors made to order. Standard 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.
