Product Description 3M ™ Fire Barrier Packing Material PM4 is designed to be used as an alternative packing material to mineral wool, fiberglass and backer rod in through-penetration firestop systems. With excellent strength and flexibility characteristics, it is an ideal through-penetration packing material. 3M ™ Fire Barrier Packing Material PM4 is also non-asbestos, mold resistant, less irritable* and inorganic. This installation-friendly material is easy-todispense and its compact packaging is optimized for portability. The smooth-textured woven material can be torn by hand, eliminating the need for a knife. 2. Applications Packing material is a part of many through-penetration firestop systems and may be used around metallic, nonmetallic, insulated pipe, HVAC and power, and communication cable penetrants. In typical commercial and industrial construction, 3M ™ Fire Barrier Packing Material PM4 can be used in gypsum and concrete assemblies. In marine applications, 3M ™ Fire Barrier Packing Material PM4 is used at bulkhead locations. 3. Specifications Along with the appropriate depth of caulk or sealant, the listed systems using 3M ™ Fire Barrier Packing Material PM4 have F Ratings of up to four hours. These systems are tested by Underwriters Laboratories, Inc. in accordance with ASTM E 814 (UL 1479) Standard Test Method for Fire Tests of Penetration Firestop Systems. Refer to the specific third-party firestop system for the 3M ™ Fire Barrier Packing Material PM4 depth and compression requirements. Prior to installation, refer to the appropriate third party listing or approval for proper installation instructions. 3M ™ Fire Barrier Packing Material PM4 has been tested in accordance with the following:
