Transformative PEEK Film Powers Everything from Cars to Chips

In the ever-evolving worlds of automotive engineering and semiconductor manufacturing, PEEK film can bear extreme conditions while boosting performance are priceless.

PEEK Film in the Automotive Industry

PEEK film meets these challenges head-on in several critical engine and drivetrain components:

① Engine Bay Components & Seals: PEEK film and molded parts are used for engine covers, seals, and gaskets.

Its exceptional heat resistance allows it to bear under-hood temperatures, while its chemical resistance prevents degradation from oils and fuels. This contributes to engine reliability and longevity.

② Bearings and Bushings: PEEK-based films, such as APTIV film, are successfully used in thrust washers for seat motors and, more critically, in high-precision rolling bearing cages.

This material's low friction coefficient and self-lubricating properties minimize wear and energy loss. Even under limited lubrication, PEEK bearings maintain smooth operation, preventing seizure and secondary damage.

③ Transmission Components: In systems like electrically controlled parking brakes and gear shift mechanisms, PEEK components help achieve high transmission ratios in compact spaces.

④ Valve Plates & Friction Materials: PEEK's low friction coefficient, excellent wear resistance, and ability to be molded into complex shapes make it suitable for components like compressor valve plates and friction elements in clutches. Its durability ensures a long service life, even with frequent start-stop cycles.

Wafer Carriers and Handling: PEEK is used to make wafer carriers, wafer handling tools (like wafer clamps and vacuum pens), and mask boxes. Its key advantages here are high purity, low particle generation, and low outgassing. This prevents contamination of silicon wafers and photomasks, which is critical for maintaining high production yields.

What is its Benefits？

① Exceptional Thermal & Chemical Resistance: bears high temperatures (continuous use up to 260°C) and resists corrosion.

② Superior Mechanical & Tribological Properties: Offers high strength, low friction, excellent wear resistance, and self-lubrication.

③ Lightweight & Durable: Replaces heavier metals, contributing to weight reduction and improved efficiency. 

④ High Purity & Stability: Low moisture absorption, minimal outgassing, and excellent electrical insulation make it ideal for cleanroom and high-precision electronic applications.

Conclusion:

PEEK film is more than just a specialty polymer; it's a critical enabler of innovation. In the automotive industry, it helps build more efficient, reliable, and quieter vehicles. In the semiconductor sector, it safeguards the integrity of the tiny brains that power our digital world.
