• High Adhesion and Durability:
Zhuheng Technology’s waterproof airtight tapes stand out in the market due to their unmatched adhesion and long-term durability, proven through rigorous testing and real-world applications. Take the Shijiazhuang Lihang Guantang and Tangyue Mansion project—a 110,000-square-meter residential benchmark in Hebei Province. This project required airtight solutions that could withstand years of exposure to temperature fluctuations, humidity, and structural movement. Zhuheng’s DPad-in and DPad-out tapes, featuring a dual-layer adhesive system with modified acrylic technology, demonstrated exceptional bonding strength. Test results show a 180° peeling strength of up to 2.4 N/mm (DPad-in) and 1.8 N/mm (DPad-out), far exceeding national standard requirements of ≥0.4 N/mm. More importantly, these tapes maintained integrity after immersion, thermal aging, and cold-drawing tests—critical for long-term performance. In another example, the Tianjin Wuqing Xinhualian Villa Renovation Project used Zhuheng’s self-adhesive tapes in a retrofit scenario where wall flatness was inconsistent. Despite challenging conditions, the tapes adhered firmly without delamination or cracking, even at temperatures as low as -10°C. The tapes’ high elongation at break (up to 411% for DPad-in) allows them to accommodate structural deformation without failure. Additionally, the pre-compressed Vitaseal 300/600 sealing tapes, co-developed with UK-based VITA Group, offer a unique combination of elasticity and compression recovery, effectively sealing joints between window frames and insulation boards. These tapes maintain their seal over decades, resisting aging, UV degradation, and mechanical stress. Customers consistently praise the tapes for reducing labor time, minimizing rework, and eliminating air leakage issues—key factors in achieving passive house certifications. The result? Buildings with lower energy consumption, improved indoor comfort, and reduced maintenance costs. Zhuheng’s commitment to durability isn’t just theoretical—it’s validated by over 15 million square meters of successful installations across China.
• Environmental Compliance and Safety Standards:
Zhuheng Technology’s waterproof airtight tapes are engineered not only for performance but also for environmental responsibility and occupant safety—making them a preferred choice among eco-conscious builders and architects. All products comply with strict international and domestic standards, including GB/T 17146-2015, GB/T 5453-1997, and CECS association specifications. For instance, the DP-HD200/210/220 special adhesives are solvent-free, isocyanate-free, and emit less than 22 g/L of VOCs—well below the 100 g/L national limit. This ensures safe handling during construction and minimal indoor air pollution post-installation. The DPad-in and DPad-out tapes are made with environmentally friendly, non-toxic materials that meet occupational health and safety requirements. Real-world validation comes from the Shanghai Shiquan Community, a central urban redevelopment project with over 200,000 square meters of ultra-low energy consumption housing. The project team selected Zhuheng’s NF30 and NF05 series tapes specifically for their zero-VOC formulation and compliance with green building three-star standards. Similarly, the Zhejiang Yuhuan Sino-German Future City Project, designed to meet both Chinese and European sustainability benchmarks, relied on Zhuheng’s eco-friendly sealing solutions to reduce carbon footprint. The company’s participation in drafting China’s first university textbook on ultra-low energy consumption building design further underscores its role in promoting sustainable practices. Moreover, Zhuheng’s products are certified for use in sensitive environments such as schools and hospitals—like Zhengzhou Foreign Language School—where air quality is paramount. Their low-emission profiles, combined with excellent water vapor diffusion resistance (Sd values ranging from 0.1m to 60.1m), ensure balanced moisture management, preventing condensation and mold growth. These attributes make Zhuheng’s tapes not just technically superior, but ethically aligned with global green building trends. As the industry moves toward net-zero emissions, Zhuheng’s commitment to safety, sustainability, and transparency positions it as a true leader in responsible construction innovation.
--- How to Choose the Right Waterproof Airtight Tape ---
• Consider the Application Area:
Selecting the right waterproof airtight tape requires careful consideration of the specific application area, climate zone, and construction method. Zhuheng Technology offers a comprehensive product portfolio tailored to different scenarios, supported by real-world case studies. For example, in the Qingdao Sino-German Ecopark Dejian Gongyuan project—a coastal city with high humidity and frequent rainfall—the outdoor side of door and window openings required a breathable membrane with high water vapor permeability. Zhuheng’s DP-out Waterproof Vapor Permeable Membrane (Sd value: 0.1m) was chosen because it allows internal moisture to escape while blocking external water, preventing wall condensation and mildew. Its 1.75mm thickness and 399 N/50mm transverse tensile strength ensured it could withstand wind pressure and structural movement. Conversely, in colder regions like Beijing, where winter temperatures drop below -10°C, the indoor side of window frames needed a vapor barrier with strong low-temperature adhesion. Zhuheng’s DPad-in Waterproof Vapor Barrier Tape, with its 2.4 N/mm peeling strength and ability to bond at -10°C, was ideal. For pipe penetrations through external walls—such as in the Beijing Zhonglv Dongyue Mansion project—Zhuheng’s GD-IN and GD-OUT sleeve tapes were used to create watertight seals around steel pipes. These tapes feature a durable plush fabric base and high-strength adhesive, ensuring long-term stability. In prefabricated buildings like those in the Shanghai Lingang New Area, self-adhesive tapes with zoned release films (e.g., DPad-out100DB) were preferred for their speed and precision. Meanwhile, in older buildings undergoing renovation, such as the Tianjin Wuqing Xinhualian Villa, adhesive-applied systems (DP-in + DP-HD220) were selected due to their tolerance for uneven surfaces. Zhuheng’s technical team provides detailed guidance based on joint width, material type, and climate, ensuring optimal performance. Ultimately, the key is matching the tape’s properties—adhesion strength, Sd value, flexibility, and temperature range—to the specific demands of the site. With over 200 successful projects across China, Zhuheng’s data-driven approach ensures customers choose the right solution every time.
