Toray Polyester Film "Lumirror"

Mechanical Properties

"Lumirror?" exhibits strong tension under appropriate pulling force and is resistant to edge damage, making it highly suitable for electrical insulation. Its mechanical properties and other characteristics are well integrated in transverse layering within machinery.

Electrical Properties

In addition to its significant insulating properties as a polyester film, "Lumirror?" also possesses strong non-conductivity, maintaining evident insulation effects even at 8000 Volt/mil (20℃, 68°F, 60Hz, ASTM D-149-64).

Cold and Heat Resistance

The melting point of "Lumirror?" is 262-263℃ (504-506°F), with an applicable temperature range from -70℃ to 150℃ (-95°F to 302°F). It can withstand short-term exposure to 180℃ (355°F) high temperatures. It contains no plasticizers (which can turn other films into sharp objects), thus maintaining insulation capability over a long period and exhibiting strong climate adaptability.

Dimensional Stability

"Lumirror?" has relatively low water absorption, resulting in excellent dimensional stability.

Chemical Resistance

"Lumirror?" is unaffected by various types of oils and most chemicals, making it resistant to waste emissions from motorcycles and other vehicles. However, due to its inherent physical properties, its resistance to alkalis or hydrolysis is not strong at high temperatures.
