• High-Strength Materials for Durability:
Zhuheng Technology’s waterproof air-tight tapes are engineered with premium-grade materials that deliver exceptional durability under extreme conditions. For example, in the Shanghai Lingang New Area Top Scientists Community project—a landmark ultra-low energy consumption development covering over 180,000 square meters—Zhuheng Shield DP-in and DP-out membranes were used to seal all window and pipe penetrations. The project required long-term performance in high-humidity coastal environments, where traditional tapes often fail due to delamination or moisture degradation. Zhuheng’s multi-layer composite structure, reinforced with high-strength non-woven fabric and UV-resistant coatings, ensured zero leakage over five years of operation. Testing data confirms that the DP-in Waterproof Vapor Barrier maintains a tensile strength of 726 N/50mm (longitudinal) and an Sd value of 52.1m, exceeding national standards by over 70%. Similarly, the DP-out Waterproof Vapor Permeable Membrane achieved a water vapor permeability of 22.2g/(m²·24h) while resisting 1000mm water column pressure for 20 hours without failure. These results were validated through independent third-party testing at China Building Materials Testing Center. Furthermore, in the Shijiazhuang Lihang Guantang and Tangyue Mansion project—spanning 110,000 square meters—Zhuheng’s self-adhesive DPad-in and DPad-out tapes were applied across thousands of joints, achieving consistent 180° peeling strength above 2.4 N/mm even after thermal aging. Such real-world success underscores Zhuheng’s commitment to delivering materials that not only meet but exceed the demands of modern green building standards.

• Advanced Production Techniques:
Zhuheng Technology leverages cutting-edge production techniques to ensure precision and consistency in every batch of waterproof air-tight tapes. The company’s factory in Shijiazhuang, equipped with imported German coating lines and automated lamination systems, enables full control over adhesive thickness, film uniformity, and curing processes. A prime example is the development of the ZHUHENG YIJIA® High-Performance Series, which integrates nano-coating composite technology and modified acrylic adhesives—originally refined through collaboration with Xi’an Jiaotong University. This innovation was first deployed in the Beijing Tongzhou Energy Smart Command Center, China’s first near-zero energy consumption building in the energy sector. The project demanded seamless integration between passive curtain wall systems and complex structural joints. Zhuheng’s DP-HD220 Special Adhesive, with its low VOC content (only 21g/L) and extrudability of 898ml/min, enabled flawless bonding even at -10°C, a critical factor during winter construction in northern China. Additionally, the zoned release film design on DPad-in and DPad-out tapes—patented by Zhuheng—prevents misapplication and improves installation accuracy, reducing rework by up to 40% on site. In the Zhengzhou Foreign Language School project, this feature allowed contractors to complete 98% of joint sealing in one pass, significantly accelerating timelines. Moreover, Zhuheng’s strategic partnership with UK-based VITA Group enabled the introduction of Vitaseal pre-compressed self-expanding sealing tapes into the Chinese market, now widely used in projects like Tianjin Wuqing Xinhualian Villa Renovation. These advanced technologies collectively reflect Zhuheng’s dedication to pushing the boundaries of what’s possible in building envelope protection.

• Contributing to Carbon Neutrality Goals:
Zhuheng Technology is not just a supplier of high-performance materials—it is a proactive contributor to China’s carbon peaking and carbon neutrality goals. Since 2019, Zhuheng has been deeply involved in drafting provincial and national standards, including Hebei’s DB13(J)T8503-2022 and Shanghai’s upcoming ultra-low energy consumption building design standard. Its products have been included in the Ministry of Housing and Urban-Rural Development’s Passive Low-Energy Building Product Selection Catalog, validating their role in enabling net-zero emissions. One of the most impactful examples is the Qingdao Sino-German Ecopark Dejian Gongyuan project, where Zhuheng’s airtightness system reduced air infiltration rates to below 0.6 ACH (air changes per hour), meeting PHI certification requirements. This level of airtightness cut heating demand by over 80%, directly contributing to a 65% reduction in annual CO₂ emissions compared to conventional buildings. In addition, Zhuheng’s entire product line is free from isocyanate and solvents, with VOC levels below 100g/L—well within the strictest environmental regulations. The company also operates a closed-loop recycling program for packaging waste and has partnered with Huanghe Science and Technology College to train future engineers in sustainable construction practices. As of 2024, Zhuheng’s materials have been used in over 15 million square meters of green building projects nationwide, equivalent to avoiding more than 230,000 tons of CO₂ annually. By choosing Zhuheng, builders aren’t just investing in superior performance—they’re actively supporting a cleaner, more sustainable future for the built environment.
