Teonex® Q51

Description

Teonex® Q51 is a flexible, slightly cloudy, biaxially
oriented polyethylene naphthalate (PEN) film.

Properties

Compared to PET polyester film, Teonex® Q51 has
optimum properties in every respect.

The increased temperature resistance results in film
approval in thermal class F (155 °C). It has a electrical
relative temperature index (RTI) of 180 °C and a
mechanical RTI of 160 °C according to UL.

Further advantages of Teonex® Q51 are:
Extremely high dielectric strength, very good mechanical
strength, high-level of stiffness, low water absorption as
well as being easy to laminate.

Application

Teonex® Q51 was specially developed for use in electric
motors with increased load as slot insulation, phase
insulation and wedges.

Standards

Class F (155 °C) insulating material.
UL approved, file no. E 206 562.
94 VTM-2 (25 to 250 µm).
RoHS compliant according to 2011/EC.

Delivery format

Film thicknesses in µm:
from 12, 16, 25, 38, 50, 75,100, 125, 188, 250

Teonex® Q51 can be supplied:
- in slit rolls from widths of 6 mm (depending on thickness) and above.
- in rolls up to a width of 1,000 mm.

Overall diameter of the slit rolls/ rolls
approx. 240, 330 or 450 mm.

Feathering:
- depth approx. 1 - 12 mm, distance approx. 1 - 10 mm
- from widths of 10 to 240 mm and thickness of 0.125 mm
