Steinerfilm® S

Special Metallized Films

Steinerfilm® S are metallized and/or customized films where the base film is neither OPP nor PET.

Polytetrafluorethylene (PTFE is better known as Teflon)

Polytetrafluorethylene  (PTFE) is well-known as a heat resistant material.

 

Teflon has the highest density of all plastic materials. The commercial thickness range starts from 12µm.

Teflon is surprisingly "soft" and can only be wound at a relatively low winding tension despite its thick gauge.

Teflon and its derivatives are PTFE, PFA, FEP or EFTE films (mainly temperature reasons) - please ask us for details.


 

Polyimide, PI (better known as Kapton)

 

Polyimide, PI (Kapton) is well-known as a heat resistant material.

 

The complex mid-molecules arrange either linear or cyclic.

The commercial spectrum of thickness starts from 12µm.

 

Polyetherimide (PEI) film
 

PEI is known as ULTEM by company SABIC, metallized by Steinerfilm. 

ULTEM™ film UTF120 is high heat and high energy density dielectric film that meets the most stringent technical demands for use in professional-grade dielectric film capacitors up to 150°C.

 

 

Polyetherketone

 

Polyetherketone consists of two basic molecular groups “ x” & “y”. It is well-known as a heat resistant material.

This material is meanwhile established in various non-electrical applications where the temperature exceeds the limits of traditional plastics like OPP and PET.

PEEK, a Poly Ether Ether Ketone, is one of the first candidates of this group of materials that have been tested as a dielectric for capacitors. PEEK and PAEK are known by company Victrex.

The thinnest gauge is about 6µm with thinner gauges under development but not yet available.
