Item # K-FAC 19, K-FAC 19 (1900ºF Rated Mineral Wool Board: 1/2" and 1" Thick x 48" x 96" Sheets)

K-FAC 19 High Temperature board is a cost effective high strength mineral fiber board with outstanding thermal insulating efficiency. It is composed of mineral fiber and selected mineral additives. An organic binder that will dissipate above approximately 475ºF is used for low temperature handling. On initial start-up. heat rise should not exceed 15ºF per minute to allow the binder to dissipate without excessive temperature rise. This will occur only on the first startup and will not adversely affect the insulation value. An inorganic binder system allows K-FAC 19 high temperature board to be used at service temperatures up to 1900ºF. The board should not be subjected to direct flame impingement as a hot face material. It's combination of high insulating value, high temperature resistance, and low cost make K-FAC 19 ideal for a variety of insulation applications.

K-FAC 19 is widely used in applications on precipitators, dryers, ducts and breeching, utility boilers, furnaces, kilns, etc. where high temperature insulating materials are required. The material is ideal for refractory backup insulation behind insulating firebrick and other refractory linings. It's exceptional strength and easy handling facilitates the use of large-size boards which translates to reduced labor costs. K-FAC 19 can be cut quickly by hand with a knife or saw for fabrication and application on the job. The recommended attachment method is by impaling on pins or studs.
