FSK tape is short name for foil scrim kraft tape. It is fire resistant, moisture barrier, very popular in thermal insulation industries. It is combination of aluminum foil, brown kraft paper,
fiberglass scrims. It can used for wrapping the air ducts and laminating the glass wool or rock wool thermal insulation, duct board joints applications. It is a cheaper solution compared to other
reinforced aluminum foil tape. Notably, it attaches well to rigid & flexible air ducts. Also, it is perfect vapor sealing for fiberglass facing joints. In addition, we have 2 way and 3 way
directional scrims foil. As a result, it can meet with your variable requirements.

Process of FSK Tape Production
NO.1
First, we weave the PE fiber mesh into 2 way directional or 3 way directional patterns. Then, layer the lightweight aluminum foil onto the fiberglass scrims.
NO.2
Second, we laminate a layer of brown kraft paper on the aluminum and fiber scrims.
NO.3
Third, we coat with very high bond natural rubber or synthetic rubber, hot melt adhesive on the basing material by our glue coating lines.
NO.4
Finally, we use our lathe slitting machines to cut the jumbo rolls to different standard or nonstandard width and length of small rolls.
