INSULTHERM ULTRAFLEX (FHN) fiberglass sleeving is ideal for the protection
of wires and hoses exposed to the heat generated from high performance engine
and exhaust components.
FHN can be used where space factor electrical insulation is sufficient, but high
temperature protection is required. It is typically used for insulation on low voltage
applications such as leads in toasters, range units, and other appliances. Ultraflex
expands slightly, allowing it to slide easily over wires and follow curves and contours
without binding.
Ultraflex undergoes a unique heat treatment process during manufacturing to
remove impurities, improve handling, and allow for easy cutting with scissors. The
absence of an acrylic binder results in an extremely flexible and versatile sleeve.
Both long-lasting and sturdy, FHN is an economical choice for low voltage and
high temperature protection.
