6 FAQs about [Ottawa Polypropylene Film Capacitor Production]
What are the raw materials for capacitor films?
The preferred choice of raw materials for capacitor films are polypropylene (PP) and polyethylene terephthalate (PET). PP is independent of frequency and temperature (<105°C) and has a high impulse stability – therefore it can be used in AC and DC applications.
Why are new polymer materials needed for capacitor films?
New polymer materials are therefore required to overcome these temperature limitations. Accordingly, a new class of engineering materials, EPN (Ethylene-Propylene-Norbornene), has been developed for capacitor films, combining the advantages of polypropylene and cyclic olefin copolymers.
Why are biaxially orientated polypropylene films used in film capacitors?
1. Introduction Biaxially-orientated polypropylene (BOPP) films are commonly used as dielectric materials in film capacitors because of their outstanding breakdown resistance, excellent charge–discharge efficiency, and largescale processability .
Which polymer is best for film capacitors?
Polymers in Film Capacitors - The Next Generation Material is available! Polypropylene is the polymer of choice for most film capacitors, but there is an inherent high temperature limit for its usage. New polymer materials are therefore required to overcome these temperature limitations.
Can a polypropylene film be used as a capacitor dielectric film?
However, the most widely used commercial capacitor dielectric biaxially oriented polypropylene (BOPP) films fail to satisfy the requirements of continuous operation above 105 °C at high electric fields.
What is the history of film capacitors?
Over the history of film capacitors, from a material perspective, the major breakthrough started with the move from paper to polymers, and especially to polypropylene, which finally became the dominant dielectric in film capacitors today.
