EPDM Acrylic Tape for High-Performance Window and Door Sealing

Introduction Window and door joints are among the most challenging details in a building envelope. They must accommodate structural movement, temperature cycles, and long-term exposure to sun, rain, and frost—all while keeping water and air out. Zhuheng Technology offers an EPDM acrylic tape designed specifically for these demanding sealing applications. Product Description Zhuheng EPDM acrylic tape consists of an EPDM membrane base, a solvent-free acrylic adhesive layer, and a PE double-silicone release liner. The tape is supplied ready to apply: simply remove the liner and press the tape into place. No additional primer or glue is required on site. Mechanical Performance Laboratory testing confirms the tape delivers 840% elongation at break, giving it the flexibility to follow joint movement without tearing. Tensile strength reaches 9.8 MPa, and tear strength is 27 kN/m. These properties allow the tape to absorb displacement while maintaining a continuous seal. Environmental Resistance The product operates across a temperature range of -40°C to 90°C. It passes a low-temperature bending test at -40°C without cracking and withstands a 30-minute water tightness test. Accelerated weathering tests show tensile strength retention of 85% and elongation retention of 75%, supporting reliable outdoor performance over time. Adhesion 180° peel strength on mirror stainless steel is 1400 N/m at 23°C and 900 N/m at -10°C, demonstrating consistent adhesion across a wide service tempera
