EXAR® SFX UL 3575
EXAR® Oil Resistant SFX 7.5KV, is the medium voltage product line of our Exar family. This innovative new material transforms Exar irradiation cross-linked polyolefin into a flexible, rubber-like material. While maintaining the excellent thermal, size, toughness and varnish release advantages of our original EXAR, the SFX maximizes flexibility over a very broad temperature range. The end result is a cable ideally suited to applications where a combination of flexibility, size and performance is required.
