The 21st China International Polyurethane Exhibition (PU China 2025) was grandly held at the Poly World Trade Center from in Guangzhou September 3 to 5. This annual event, which has drawn global attention in the polyurethane industry, brought together over 200 enterprises from around the world, with an exhibition area spanning 20,000 square meters.

The exhibition covers the whole industry chain of polyurethane industry from raw materials to products, equipment, scientific research and other links, providing visitors with one-stop solutions.

01 Exhibition: the innovation gathering place of polyurethane industry

The exhibition attracted global leading enterprises such as Wanhua Chemical, Huntsman and Xiangyuan New Material to compete on the same stage, showing the latest breakthroughs in the polyurethane industry in the fields of green and low-carbon, circular economy and composite materials. POLYWIN Chemical, located at 1130, attracted special attention and showed a number of innovative technologies and products.

In the face of increasingly strict environmental requirements and continuous upgrading of performance, this exhibition brings together the world's leading enterprises to explore the way to break the game and develop new paths for polyurethane materials.

During the exhibition, a number of seminars and technical exchanges were held to share the latest technological advances and market opportunities in the polyurethane industry. These activities provided a platform for exhibitors and visitors to deeply communicate, discuss industry trends and share innovative achievements.

03 Innovative achievements: HDI and H12MDI aliphatic systems

POLYWIN Chemical's HDI and H12MDI prepolymers deliver optimal physical properties for all aliphatic elastomers, establishing them as essential building blocks for premium casting elastomers and coating formulations. The company's latest aliphatic product line utilizes HDl monomers and proprietary low-free technology to create systems with less than 0.1% free HDI monomers, enabling the application of HDI that was previously impractical due to high vapor pressure.

The aliphatic system has a very long operational time and excellent UV resistance. They also have excellent hydrolysis resistance at high temperatures.

04 Technical accumulation: low free technology is widely used

Our customers can achieve exceptional toughness, dynamic performance, and processability without excessive exposure to harmful vapors from residual TDI monomers. POLYWIN Chemical's Madisonol VE series enhances the technical performance and safety of TDI systems. The free TDI level is reduced to below 0.1%, which not only significantly improves workplace safety but also offers lower viscosity, extended casting lifespan, faster demolding, and reduced internal heat compared to traditional systems.

POLYWIN Chemical's low free system has two series, polyether and polyester, with hardness range from 70 Shore A to 75 Shore D. Special formulations outside this range can also be provided. The diversity is self-evident.

05 Castable plastics: POLYWIN Chemical's Madisonol PM polyurethane system, strong and tough performance characteristics

The Madisonol PM polyurethane system delivers engineering-grade strength, enhanced toughness, and impact resistance in two-component polyurethane applications, comparable to nylon injection molding. Unlike thermoplastics, PM series products offer superior cost-effectiveness for small-batch production due to lower molding costs, making them ideal for prototyping. Available in transparent and opaque white options with easy coloration, the system features a hardness range of 80 Shore D to 85 Shore D (with a modulus up to 2000 MPa) and a heat deflection temperature exceeding 105℃.

06 Industry impact: Promoting the application boundary of polyurethane materials

The innovative technology of POLYWIN Chemical is of great significance to promote the development of the entire polyurethane industry. With the transformation of lightweight and environmental protection in the automotive industry, especially in electric vehicles, polyurethane materials have gained a broader application space.

In the context of the deep restructuring of the global polyurethane industry chain, POLYWIN Chemical has continuously enhanced its core competitiveness by improving the stability of the supply chain and increasing the investment in technology research and innovation.

The company's technological innovation not only meets the market demand for high-performance materials, but also opens up new market opportunities for the application of polyurethane materials in new energy, green building, intelligent equipment and other fields.
