Butyl tapeAge and Weather Resistant Butyl Rubber Formula 100% Solids Content Used as Pipe Line Joint Anticorrosion and Exterior Primary Spacing and Glazing SealDesigned High Intensity Adhesive between Two SurfacesIDEAL Butyl Tape is an extruded, preformed architectural glazing tape and fill in the pipe line joint tape furnished on release paper rolls. Based on a butyl rubber formulation with proven age and weather resistant properties, it is designed to create a long lasting, flexible weather seal between two surfaces which will be subjected to normal expansion/contraction and wind loading forces. It is used as fill pipe line joint; also used to seal architectural surfaces such as metal to metal joints, metal to glass, metal to plastic, etc. The thickness is designed to be compressed approximately 10 percent at installation to accommodate surface alignments.Specification of Butyl tape:Color of Butyl Adhesive: Black ; Color of Separate paper/film: yellow or white and transparence;Thickness of Tape:2mm,3mm ; Width of Tape:20mm,30mm,50mm ;Length of Each Roll:6m,10m,20m,30m.
