Product Description
Hollyfoam®Self-expanding Sealant Tape
Self-expanding polyurethane foam tape is a pre-compressed, self-expanding foam tape based on a modified material from polyurethane foam. The polyurethane foam expands uniformly to provide a high performance, all-weather seal and is treated with a pressure-sensitive adhesive on one side for fixing to the side of the joint. It is specially designed for sealing gaps around windows and doors, expansion joints in concrete, joints between precast concrete slabs and profile panels.
