NF-77 :  NF-77 is a UL listed flame retardant vulcanized fibre with good tracking rate,
high ampere-arc, and hot wire ignition rate. It has almost the same workability as the standard grade, but can be easily flexed if slightly pre-heated.

      NF-77 Characteristic

K-57 :  K-57 is listed in Class E of Japan Electricity Regulation. It has an ideal incorporation of good workability of fibre and dimensional stability.
