Technology & Advantages

CY20DS/SS is an antistatic precoated polyester film for optoelectronic display, electronic packaging, and surface protection applications. Through the DT25 or DT27 coating system, it provides an antistatic surface while maintaining a transparent appearance, friction resistance, and chemical resistance.

Core Values

Antistatic performance:
DT25 (blue coating) and DT27 (colorless coating) provide excellent, durable, and stable antistatic performance with typical surface resistance values.
Transparent appearance:
Transmittance and haze values support display and protective film applications. DT25 offers a blue tint while DT27 remains colorless.
Processing compatibility:
Friction resistance and chemical resistance support downstream film pasting, protection, and processing validation for various applications.
Broad application coverage:
Used for mobile phone panels, TFT-LCD backlight modules, electronic packaging, LCD, polarizers, and optical lens surface protection.

Applications

Mobile phone panel
Used for surface protection or film-pasting applications related to mobile phone panels.
TFT-LCD backlight module
Used in material applications related to TFT-LCD backlight modules.
Electronic packaging
Suitable for electronic packaging applications requiring an antistatic surface.
LCD, polarizer, and optical lens surface protection
Used for surface protection or film-pasting applications for displays, polarizers, and optical lenses.
