PVB Interlayer Film Manufacturers

PVB interlayer can effectively isolate noise and improve the sound insulation effect of building and car glass

In today’s modern society, where urban noise pollution is increasingly becoming a challenge, the demand for soundproofing solutions in architecture and automotive design is stronger than ever. One of the most effective materials in improving acoustic performance in glass applications is the Polyvinyl Butyral (PVB) interlayer. PVB interlayers not only provide enhanced safety and durability for laminated glass but also significantly contribute to sound insulation, making them a critical material in both building and automotive industries.

At the forefront of this advanced material technology is Jiangsu Daruihengte Science & Technology Co. Ltd, a leading company that has been dedicated to the development, manufacturing, and promotion of high-performance PVB film since its establishment in 2010. With over a decade of expertise, Daruihengte has become a reliable partner in providing high-quality polyvinyl butyral film for a wide range of applications, including photovoltaic, aerospace, defense, construction, and automotive sectors.

The key advantage of pvb interlayer film lies in their viscoelastic properties, which enable them to dampen sound vibrations that typically pass through standard monolithic or tempered glass. When used in laminated glass structures, the pvb film absorbs and dissipates acoustic energy, resulting in a significant reduction in noise transmission. This makes PVB interlayered glass ideal for urban buildings located near highways, airports, or industrial zones, as well as for automobiles where interior comfort and cabin quietness are important performance features.

Daruihengte’s commitment to innovation is exemplified by its investment in state-of-the-art production technologies. The company owns three advanced polyvinyl butyral interlayer film production lines, including the first automatic die head for PVB film with a width of 3.6 meters in China. This setup allows the company to produce PVB films with consistent thickness, clarity, and acoustic performance, all while maintaining high levels of quality control. Each production line is equipped with comprehensive product testing equipment to ensure that every roll of PVB film meets international standards.

Located on a sprawling 40-acre facility, Daruihengte combines large-scale production capabilities with rigorous quality assurance. The company has achieved ISO9001:2015 quality management system certification and ISO14000 environmental management system certification, demonstrating its dedication to both product excellence and sustainable practices.

In order to further expand its global reach, the company has established Malaysia Darui Technology SDN. BHD. and Hong Kong Hente Group Limited as strategic international branches. These initiatives have helped Daruihengte successfully export its PVB products to over 20 countries and regions, including markets in Europe, the Americas, Southeast Asia, the Middle East, and Africa. The “Darui” brand of PVB films has earned widespread recognition for reliability, performance, and innovation.

Daruihengte offers a wide variety of PVB interlayer films tailored to different acoustic requirements. For instance, sound-insulating PVB films for building glass are specifically engineered to reduce noise levels up to 30–35 decibels, significantly enhancing the comfort of indoor environments. In the automotive sector, Daruihengte's PVB films help reduce road noise and engine vibration, contributing to a quieter, more pleasant driving experience.

Moreover, these acoustic benefits do not come at the expense of other important features. Daruihengte’s PVB films maintain excellent optical clarity, UV resistance, and impact resistance, which are essential for both safety and aesthetics in laminated glass products. Whether it’s for high-rise curtain walls, residential windows, or vehicle windshields, Daruihengte’s solutions provide multifunctional performance in a single material.

Looking ahead, Jiangsu Daruihengte Science & Technology Co. Ltd remains committed to serving both middle- and high-end markets around the world. With growing demand for high-quality laminated glass solutions, the company continues to invest in R&D and global collaboration, striving to bring better acoustic, safety, and environmental solutions to its clients.

As the need for quiet, safe, and energy-efficient environments continues to rise, PVB interlayers stand out as a practical and effective solution. With proven performance in noise isolation, Daruihengte’s PVB interlayer films not only meet but exceed industry expectations. Whether for a high-speed car or a peaceful home in a bustling city, Daruihengte provides the silent strength behind the glass.
