Transmittance Test - Measure the transmission of HCK optical conductive film with MFS630, 550nm band:
Transparent thin‑film heating sheet
The transparent thin‑film heating element covers the entire surface of the heater, delivering a very rapid and safe heating profile for the product. Featuring an ultra‑thin thin‑film heater structure, it can be affixed on either side using high‑performance double‑sided adhesive or ordinary double‑sided adhesive without obstructing visibility, with a light transmittance above 70%‑80%.
Features
• High light transmittance up to 85%, higher than that of conventional glass.
• Resistant to strong light; image quality remains clear when attached to the screen.
• Ultra‑light and ultra‑thin. Heats up rapidly and evenly, reaching the set temperature (50℃) within 5 seconds after power‑on, with a maximum temperature resistance of 120℃.
• Self‑adhesive for easy application, space‑saving, simple and convenient to operate.
• Customizable sizes, specifications and shapes can be developed according to customer requirements.
• Voltage can be designed and produced ranging from 1.5V to 380V.

Remarks
|
Due to Kapton's stability and solvent resistance in vacuum, it is often used in medical and aerospace applications.
Withstands harsh environments |
Silicone rubber is cheaper than Kapton. It is used in industrial and commercial applications and is usually hardened onto metal parts.
|
Suitable for high‑temperature environments or applications requiring ultra‑high temperatures, featuring a uniform‑temperature design
|
Polyester shares many properties of Kapton, yet it is a more cost‑effective option and features better water resistance.
