PVC foam tape made of foam with a density of 250±30kg/m3, coated on both sides with high-viscosity acrylic adhesive, with a blue film lining for easy peeling. It has a microporous structure that allows the structural silicone to cure on all sides of the seam. It is often used to create a seal between double glazing units and door and window frames.
