Automotive PVB Interlayer Film

Automotive PVB Interlayer Film has passed rigorous weather resistance tests and is suitable for complex and changing driving environments

In the automotive industry, safety and durability are paramount. One of the key components ensuring both is the Automotive PVB Interlayer Film , a high-performance material used in laminated safety glass, particularly in vehicle windshields. Jiangsu Daruihengte Science & Technology Co., Ltd, established in 2010, has become a trusted name in the production and innovation of Automotive PVB Interlayer Films that have passed rigorous weather resistance tests, making them ideal for use in complex and changing driving environments.

High Standards in Product Performance
Jiangsu Daruihengte specializes in the development, manufacturing, and promotion of polyvinyl butyral functional films, ordinary films, and PVB recycling technologies. Its Automotive PVB Interlayer Film is engineered to withstand extreme temperatures, humidity, UV exposure, and mechanical stress — all of which are critical factors in ensuring long-term performance and safety in vehicles.

Through extensive research and testing, the company’s PVB interlayer films have successfully passed stringent weather resistance tests, including thermal cycling, humidity resistance, UV aging, and salt spray corrosion tests. These evaluations simulate real-world conditions such as desert heat, tropical humidity, and coastal corrosion, proving that Daruihengte's products can maintain structural integrity and optical clarity under harsh environmental stresses.

Advanced Production Capabilities
Located on a site spanning over 40 acres, Jiangsu Daruihengte operates three dedicated production lines for PVB interlayer films. Among these, the company proudly owns China's first fully automatic die head with a width of 3.6 meters — a technological breakthrough that enables large-scale, high-precision film production tailored to automotive specifications.

Each production line is equipped with a comprehensive set of product testing equipment and facilities, ensuring that every batch of Automotive PVB Interlayer Film meets international quality standards. The company has also obtained ISO9001:2015 Quality Management System Certification and ISO14000 Environmental Management System Certification , reflecting its commitment to excellence and sustainable development.

Designed for Real-World Applications
The automotive environment presents unique challenges — from sudden temperature changes during cross-country travel to prolonged sun exposure in urban settings. Daruihengte’s Automotive PVB Interlayer Film excels in these scenarios by maintaining strong adhesion between glass layers, preventing shattering, and reducing the risk of injury in the event of impact or collision.

Moreover, the film offers excellent optical clarity, ensuring unobstructed driver visibility. It also provides effective UV protection, blocking more than 99% of harmful ultraviolet rays, which helps protect both passengers and interior car materials from degradation due to sunlight exposure.

Beyond safety, the PVB interlayer contributes to enhanced acoustic insulation, significantly reducing road and wind noise for a quieter, more comfortable ride. Additionally, it supports advanced functionalities such as infrared blocking and smart glass integration, aligning with modern trends in automotive design and energy efficiency.

Global Market Expansion and Industry Recognition
To better serve the growing global demand, Jiangsu Daruihengte has expanded its business internationally. The company has established overseas branches including Malaysia Darui Technology SDN. BHD. and Hong Kong Hente Group Limited , enabling localized support and faster delivery to customers across Europe, the Americas, Southeast Asia, the Middle East, Africa, and beyond.

With steadily increasing production capacity and sales, the "Darui" brand of PVB films has gained widespread recognition in the industry. The company is committed to serving both mid-end and high-end customers domestically and internationally, offering reliable, high-quality solutions that meet evolving automotive needs.

As the automotive industry continues to evolve, so too must the materials that ensure vehicle safety and performance. Jiangsu Daruihengte Science & Technology Co., Ltd stands at the forefront of this advancement with its Automotive PVB Interlayer Film — a product that has not only passed rigorous weather resistance tests but is also ideally suited for the complex and dynamic environments in which today’s vehicles operate. With a strong foundation in R&D, advanced manufacturing capabilities, and a global outlook, Daruihengte is shaping the future of automotive glass safety and innovation.
