Solvay Introduces New KetaSpire® PEEK Grades for Precision ABS/ESC Brakes and Electric Vehicle Components

Solvay today announced the launch of a new grade of KetaSpire® PEEK, KT-850 SCF 30, designed for precision braking systems and electric vehicle electronic pump assemblies
.

Carbon fiber-filled PEEK is typically used for anti-lock braking system (ABS) and electronic stability control (ESC) components such as lifters, shrapnel, and plungers
.
The new KT-850 SCF 30 grade can further replace metal (aluminum) by improving the flow characteristics of the material and the surface finish of the part
.

The ABS/ESC plunger plays a key role in the functioning of the hydraulic unit of the system
.
The system combines an electronic pump, an electronic control unit (ECU), valves that control wheel brake pressure and sensors that measure wheel speed
.
The plunger is responsible for operating the movement of the valve by controlling the supply of brake fluid
.

Replacing metal with polymer plungers requires materials like KetaSpire® KT-850 SCF 30, which balances high performance properties including coefficient of friction, mechanical strength, dimensional tolerance control and sealing capabilities
.

Replacing aluminum in precision components such as ABS plungers can reduce overall costs and increase productivity
.
KetaSpire® KT-850 SCF 30 provides the fluidity required to fill parts, which are approximately 15mm in length, while also meeting the tight tolerances required for ABS/ESC plungers
.
The processability of KetaSpire® KT-850 SCF 30 is superior to that of existing materials, resulting in greatly increased throughput, improved surface finish, and better sealing and mechanical properties
.

“The new carbon-filled KetaSpire® PEEK grade comes at a critical time when manufacturers are looking to enhance sealing and mechanical performance
.
This means it is a true solution for the electric vehicle market and we are proud that it is our complete brake part of a high-performance solution for the system
,” said Brian Baleno, Head of Transportation Industry Marketing, Solvay Materials Division.
