Shanghai, April 24, 2026​ – The highly anticipated CHINAPLAS 2026, Asia's largest international plastics and rubber trade fair, kicked off today at the National Exhibition and Convention Center (Shanghai). Among the sea of exhibitors, DAFU New Materials ​ emerged as a standout star, capturing significant attention from industry professionals worldwide with its groundbreaking High-Performance PEEK (Polyether Ether Ketone) Film.

The exhibition hall buzzed with activity at DAFU booth, where the company showcased its latest innovations in specialty engineering plastics, signaling a major shift in the global supply chain for high-end polymer films.

High-Performance PEEK Film: The "Golden Film" for Extreme Environments

DAFU New Materials used the platform of CHINAPLAS 2026 to highlight the superior properties of its PEEK film, often referred to as the "golden film" in the engineering plastics industry. Designed to replace metals and underperforming polymers, Dafon’s PEEK film offers a unique combination of characteristics:

• Exceptional Thermal Stability:​ With a continuous service temperature up to 240°C and short-term resistance to 300°C, it outperforms standard engineering plastics.
• Superior Mechanical Strength:​ High tensile strength, rigidity, and excellent wear resistance ensure durability in demanding applications.
• Outstanding Chemical Resistance:​ Virtually insoluble in any organic solvent, making it ideal for harsh chemical environments.
• Excellent Dielectric Properties:​ Stable dielectric constant and low dissipation factor, even in high-frequency and high-humidity conditions.
• Inherent Flame Retardancy:​ Meets strict UL94 V-0 standards with low smoke emission, crucial for aerospace and rail transit.

These attributes position DAFU PEEK film as a critical material for next-generation technologies in electric vehicles (EVs), 5G/6G communications, semiconductor manufacturing, and medical implants.

Live Demonstrations Drive Engagement at CHINAPLAS

At the DAFU booth, live technical demonstrations and sample displays drew crowds of engineers, procurement managers, and R&D experts. Key application highlights included:

• EV Motor Insulation:​ DAFU presented PEEK film solutions for slot liners and phase insulation in EV motors. Compared to traditional materials like Nomex or PI film,DAFU product offers superior thickness uniformity and heat resistance, enabling higher power density and longer motor life.
• High-Frequency Copper Clad Laminates (CCL):​ Addressing the demand for low-loss substrates in 5G/6G infrastructure, DAFU showcased its ultra-smooth PEEK film designed for high-speed signal transmission, sparking interest from leading PCB manufacturers.
• Semiconductor & Electronics Protection:​ Samples demonstrating the film's use as a protective layer for flexible circuits and precision components highlighted its cleanroom compatibility and anti-static options.

Throughout the event, DAFU technical team engaged in deep discussions with visitors regarding customization, processing techniques, and performance validation, solidifying the company’s reputation as a reliable technology partner.

Breaking the Monopoly: Accelerating Domestic Substitution

For years, the high-performance PEEK film market has been dominated by a handful of international giants. DAFU  New Materials has successfully disrupted this landscape through persistent R&D investment, mastering core technologies from resin synthesis to biaxial stretching processes.

By presenting at CHINAPLAS 2026—the premier stage for the rubber and plastics industry—DAFU  demonstrated that China possesses the capability to produce world-class specialty films. This breakthrough provides downstream industries with a stable, cost-effective, and high-quality alternative for import substitution.

Industry analysts on-site noted that companies like DAFU  are pivotal to the "dual circulation" strategy, strengthening the resilience of global supply chains while driving innovation from China to the world.

Future Outlook: From Spotlight to Market Leadership

Reflecting on the overwhelming response at CHINAPLAS, a spokesperson for DAFU New Materials stated: “The feedback from CHINAPLAS 2026 validates our commitment to high-performance polymers. Moving forward, we will scale up production capacity, deepen collaborations with downstream leaders, and continue to push the boundaries of what PEEK film can achieve.”

With its sights set on becoming a global leader in specialty films, DAFU New Materials is transitioning from merely attracting attention to actively shaping the future of high-tech manufacturing.
