SPD sound insulation board debuted at the Sound Expo for the first time

SPD sound insulation panels lead the transformation of new materials in building acoustics.

Today, (May 11, 2026), the eighth China Acoustic Industry Expo CAAF2026, which has attracted much attention from the industry, opened grandly at the Nanhai International Convention and Exhibition Center in Foshan, Guangdong. With the theme of "Sound drives the future, wisdom gathers in the South China Sea", this exhibition gathers high-quality resources from the entire acoustic industry chain and builds a professional platform for technical exchanges, industry docking, and business cooperation. At this annual event in the field of acoustics, the SPD sound insulation and insulation board independently developed by Zhejiang Keda New Building Materials Co., Ltd. made its world debut for the first time. With its disruptive product performance and innovative technology, it became the focus of much attention at the exhibition site, injecting new vitality into the fields of architectural acoustics and energy-saving insulation.

As an innovative enterprise deeply involved in the field of new building materials, Zhejiang Keda New Building Materials Co., Ltd. has always focused on the pain points of building energy conservation and noise control industries, deeply engaged in technology research and development, and after many iterative upgrades, it has successfully created SPD sound insulation and insulation panels, a high-performance innovative product. This appearance at the Foshan Acoustic Expo is a concentrated display of brand strength and technological achievements. It is also an important milestone for the company to lay out the national acoustic building materials market and empower the upgrading of the green building industry.

This product adopts an innovative formula of water-based polyurea, has a micron-level fine cell structure and ultra-high closed porosity, and is equipped with internal plasticized elastic soft segment molecular chain technology to achieve sound insulation, thermal insulation, flame retardant, environmental protection, and durability. It perfectly solves the industry problems of traditional building materials such as difficulty in balancing sound insulation and thermal insulation, insufficient environmental protection, and short service life. In terms of core performance, SPD The performance of sound insulation and insulation boards is particularly outstanding: in terms of acoustics, it can effectively dampen and absorb sound wave vibration energy, greatly reducing airborne sound and impact noise, and the noise reduction effect far exceeds the conventional industry standards, creating quiet and comfortable spaces for residences, hotels, schools, hospitals and other scenes; in terms of thermal insulation and energy saving, the thermal conductivity of the product is extremely low. Effectively blocks heat conduction, reduces building energy consumption, and promotes green and low-carbon building construction; in terms of environmental protection and safety, it uses water as the foaming medium, contains no volatile organic compounds, is non-toxic and has no odor, and is green and environmentally friendly during construction and use. At the same time, it is added with a halogen-free flame retardant formula, which has excellent flame retardant performance and comprehensively guarantees building safety. In addition, the product also has the advantages of convenient construction, strong adaptability, and good weather resistance. It can be widely used in building floors, walls, roofs and other parts, and is suitable for residential real estate, commercial buildings, public venues, industrial plants and other diverse scenarios. It can fully meet the current construction industry"s all-round needs for acoustic optimization, energy saving and consumption reduction, safety and environmental protection, and provide one-stop high-performance building materials solutions for construction projects.

Merchants from all walks of life are sincerely invited to visit the booth F1A17 of Zhejiang Keda New Building Materials Co., Ltd. at the Foshan Acoustic Expo. The exhibition will last until May 13 to experience product performance in depth, exchange technical solutions, assess product strength, seek cooperation business opportunities, and work together to create a bright future for new architectural acoustic materials!
