Specifications

Varglas 240 Silicone Rubber sleevings conforms to and is listed on the qualified products list for, MIL-l-3190/9, latest revision (Grade A); and exceeds the requirements of UL 1441, Table 19.8; NEMA TF-1, Type 5; and ASTM-D372.

Under the Component Program of Underwriters Laboratories, Grade A Varglas 240 Silicone Rubber is recognized for 240°C, 600 volt service and complies with VW-1 flammability requirements under UL File #E63450. CSA International certifies the use of Grade A for 240°C, 600 volt service and VW-1 flammability under CSA File #LR58486.

Applications

Varglas 240 Silicone Rubber sleevings are suitable for industrial applications such as motors, generators, transformers and engines; where superior dielectric protection at elevated temperatures of 240°C is critical. In addition to automotive engines, Varglas 240 Silicone Rubber flame resistances and wide-operating temperature ranges make it particularly well suited for aircraft engines and other aerospace applications; where it satisfies electrical and thermal barrier requirements while providing the added benefit of lighter weight.

Specifications

Varglas Viton® 231 sleevings conforms to, and is listed on the qualified products list for, MIL-l-3190/7, latest revision (Grade A), and exceeds the requirements of NEMA TF-1 and ASTM-D372.

Under the Component Program of Underwriters Laboratories, Varglas Viton® 231 Sleevings complies with VW-1 flammability requirements under UL File #E53690. It is incorporated in systems work, per UL Safety Standard 1446, to facilitate product acceptance by UL.

Applications

Varglas Viton® 231 sleevings are used when the need to maintain a silicone-free environment is important. It's excellent resistance to flames and abrasion make it ideally suited for the insulation of leads and connections of critical electrical components. Viton® 231 is used in DC generators and motors to reduce arcing problems; as well as for wire harnesses in areas where continuous operating temperatures run as high as 220°C. Varglas Viton® 231 is also used in transformers where resistance to high impingement velocity oils is required and, generally, where better solvent and oil resistance is needed.

Specifications

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.

Applications

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.
