Pre Compressed Foam Tape
Expanding foam tape is a constructed from pre-compressed, soft polyurethane foam and can be found used in joints that are subjected to water vapour. It performs brilliantly in applications that need to be sealed against driving rain and the addition of self-adhesive backing.
Description
Product description:
Pre Compressed Foam Tape is made of impregnated permanently elastic fine cell soft polyurethane foam, which expands slowly and evenly to provide a seal against wind and driving rain.After application the tape expands to fill gaps and also adapts to uneven surfaces.Supplied in various roll lengths and widths.
Features：
●Weather seal for wind-driven rain
●Vapour diffusion permeable
●Self-adhesive backing
●Seals against uneven surfaces
●No shrinkage or blow-out due to closed-cell breakage
●Acoustic and thermal insulation
