• DP-in and DP-out Membranes:
Zhuheng’s DP-in and DP-out waterproof vapor barrier and permeable membranes are engineered for precision and durability in ultra-low energy consumption buildings. The DP-in Waterproof Vapor Barrier (adhesive-applied type) features a multi-layer composite structure with high tensile strength (726N/50mm longitudinal), excellent aging resistance, and a plush fabric base that integrates seamlessly with cement mortar. Its Sd value of 52.1m ensures superior vapor barrier performance, effectively preventing condensation and mold. Meanwhile, the DP-out Waterproof Vapor Permeable Membrane, with a thickness of 1.75mm and a water vapor transmission rate of 1.7×10⁻⁵g/(m²·s·Pa), allows moisture to escape while blocking rainwater—critical in humid climates. These membranes are used in high-performance applications such as sealing joints between windows and walls, pipe penetrations, and prefabricated panel connections. For example, at the Beijing Tongzhou Energy Smart Command Center—the first near-zero energy consumption building in China’s energy sector—Zhuheng’s DP-in and DP-out membranes were applied to the passive curtain wall system, contributing to its successful certification under German PHI standards. The combination of high adhesion, flexibility, and compliance with national and regional standards makes these membranes ideal for complex architectural designs where long-term integrity is non-negotiable.
• Special Adhesives and Tapes:
Zhuheng’s DP-HD200/210/220 Special Adhesives and DPad-in/out tapes represent a leap forward in sealing technology. The DP-HD220 adhesive, formulated with international-grade raw materials, offers exceptional low-temperature performance (usable down to -20°C), zero VOC emissions, and a sagging degree of 0mm—ensuring stable bonding even on vertical surfaces. With a surface drying time of just 2 hours and an elastic recovery rate of 94%, it outperforms conventional sealants in durability and ease of use. The DPad-in and DPad-out self-adhesive tapes take this further with zoned release films and exposed edges, enabling precise application and eliminating misalignment during installation. At the Zhengzhou Foreign Language School project, these tapes were used to seal window joints in a high-rise educational facility, reducing air infiltration by over 90% and significantly improving indoor thermal comfort. The tapes’ ability to bond directly to metal, concrete, and plastic substrates without priming saves time and labor. Additionally, the Vitaseal pre-compressed self-expanding sealing tape—licensed from UK-based VITA Group—has been deployed in cold regions like Tianjin Wuqing Xinhualian Villa, where it provides long-term windproof, soundproof, and heat-insulating performance in joints between external insulation and window frames. These products collectively form a comprehensive sealing system that enhances building longevity, reduces maintenance costs, and supports green building certifications.

• Research and Development Initiatives:
Zhuheng Technology’s innovation engine is fueled by deep R&D investment and strategic partnerships. The company has introduced internationally advanced production and testing equipment, ensuring every product meets or exceeds global benchmarks. Its collaboration with Xi’an Jiaotong University as an off-campus practical education base and Huanghe Science and Technology College has cultivated a pipeline of skilled engineers and technicians dedicated to sustainable building technologies. Furthermore, Zhuheng’s strategic alliance with the UK’s VITA Group has brought cutting-edge polyurethane foam sealing tapes—such as Vitaseal 300/600—into the Chinese market, offering fire-resistant, low-thermal-conductivity (0.046W/(m·K)) solutions for extreme weather zones. The company also leads in developing new product lines like the DP-in ES and DP-out ES series, specifically designed for hot-summer and cold-winter climates, featuring enhanced plasterability and moisture control. These innovations are not developed in isolation; they are informed by real-world data from over 200 completed projects. For instance, feedback from the Shanghai Shiquan Community—where more than 200,000 square meters of housing were built with strict airtightness protocols—led to improvements in adhesive viscosity and peel strength. Zhuheng’s R&D team continuously refines formulations using MS technology and nano-coating composites, resulting in products like NF30 and NF05 that offer super storm resistance and environmental safety. Their participation in drafting national standards such as CECS and China’s first university textbook on ultra-low energy consumption design underscores their role as thought leaders. These efforts position Zhuheng not just as a supplier, but as a driving force behind the evolution of green building science in China.
