Maxflex Duct Tape is made from EPDM / Neoprene modified elastomeric self-adhesive foam gasket. This gasket foam tape is specially made with good compression set to prevent air leakage at duct flange connections of the air-ducting system (both cooling & heating). Maxflex Duct Tape also reduce noise and adsorb vibration. The cross linked closed cell structure and characteristic of having low thermal conductivity value also serve as an ideal thermal insulation to prevent condensation and heat transfer. The acrylic pressure sensitive glue coated on the tape ease installation work onto the surfaces of flange connection joints.
