The Kaladex® film is a PEN (polyethylene naphthalate) solution designed to meet the most demanding industrial environments, particularly in the energy, mobility, and power electronics sectors.
In these applications, manufacturers must contend with critical constraints: rising temperatures, high electrical stresses, component miniaturisation, and increased reliability requirements. In this context, the choice of insulating materials becomes a key lever for performance and durability.
Kaladex® film represents a strategic alternative between standard PET films and high-performance materials such as polyimides, offering an excellent compromise between cost, thermal performance, and dimensional stability.
ADDEV Materials supports industrial manufacturers at every stage of the project: from selecting the right Kaladex® grade to bespoke processing (cutting, laminating, combining) in order to deliver components that can be directly integrated into your systems.
The Kaladex® film is widely used in systems requiring reliable and durable electrical insulation:
Thanks to its continuous operating temperature of up to 180°C and its superior rigidity, it guarantees stable performance in critical environments.
Kaladex® and Teonex® films both belong to the PEN film family, but have different positioning depending on applications.
The film Kaladex® is notable for:
The Kaladex® film is a biaxially oriented PEN (polyethylene naphthalate) polyester film, developed to offer superior performance to conventional PET films whilst remaining more accessible than polyimide films.
Its specific molecular structure gives it a unique combination of mechanical, thermal, and electrical properties, particularly suited to demanding industrial environments. Notably, it exhibits a higher glass transition temperature (121°C compared to 78°C for PET), as well as excellent dimensional stability at high temperatures.
Thanks to these characteristics, the Kaladex® film allows:
It is thus used in critical applications such as electric motor insulation, flexible printed circuits (FPC), high-performance capacitors, and energy storage systems.
ADDEV Materials supports industrial manufacturers in the selection and transformation of Kaladex® films for direct integration into their systems.
Our capabilities include:
The Kaladex® film is used across many demanding industries:
Its unique combination of properties allows it to replace PET in critical applications and avoid the cost of polyimide.
The choice of a Kaladex® PEN film depends on several technical factors.
The choice of film depends directly on the thermal requirements.
Kaladex® can be used at temperatures of up to 180°C, making it ideal for harsh environments.
For high-voltage applications, favour grades offering high dielectric strength and excellent electrical stability.
Its high rigidity and low deformation ensure excellent performance in stressed systems.
Kaladex® can be processed just like PET film, making it easy to incorporate without altering existing processes.
