A seaming tape for joining pieces of floor-covering together, such as carpet or resilient floor covering material, and a method for using the same to join adjacent pieces of planar material is provided. The seaming tape can include an upper mesh tape portion and a lower blocking tape portion that is narrower in width than the mesh tape portion. The mesh tape portion can further include a pressure-sensitive adhesive to hold the blocking tape portion in position.
摘要:
A pipe insulation product including a core of insulating material and a laminate. The core includes a cylindrical outer surface; a cylindrical inner surface; and a wall extending between the cylindrical outer surface and the cylindrical inner surface. The laminate includes a metallized polymeric film sheet layer forming an inner layer, a scrim, a porous media sheet layer, and a polymeric film sheet layer forming an outer exposed layer bonded together via an adhesive. The laminate is coextensive with and bonded to the cylindrical outer surface of the core and the laminate and core are flexible so that the core and laminate can be opened, placed about a pipe, and closed without degrading the laminate.
