Clear PET Film for Home Appliances Control Panels
In the modern home appliance industry, the Human-Machine Interface (HMI) is the primary touchpoint that defines brand quality. Washing machines and dryers operate in demanding environments exposed to high humidity, elevated temperatures, and aggressive chemical detergents. Our premium highly flexible, optically clear PET film series with advanced surface treatments is engineered to eliminate premature aging and surface degradation, ensuring long-term aesthetic appeal and zero-defect functionality.
A superior appliance overlay substrate requires precise engineering beyond mere transparency. Below are the key parameters engineered into our PET films and the logic behind them:
| Property | Typical Value | Test Method | Engineering Rationale |
|---|---|---|---|
| Total Transmittance | ≥ 91.5% | ASTM D1003 | Lossless Backlighting: Ensures maximum light transmission for HD TFT-LCD screens and color LEDs, preventing backlight diffusion or ghost images. |
| Haze | ≤ 0.5% | ASTM D1003 | Premium Mirror Finish: Exceptional low-haze guarantees high color fidelity for reverse printing, rendering deep blacks without a milky appearance. |
| Thermal Shrinkage | MD ≤ 0.8%TD ≤ 0.2%(150°C / 30min) | ASTM D1204 | Anti-Warping & Precise Registration: Crucial for multi-pass curing of conductive silver pastes and UV inks, preventing registration misalignment. |
| Tensile Strength | MD ≥ 190 MPaTD ≥ 210 MPa | ASTM D882 | High Tactile Longevity: Built to withstand high-speed embossing and millions of mechanical actuations without stretching or cracking. |
| Ink Adhesion | 5B (100/100) | ASTM D3359 | Secure Circuitry: Features a specialized chemical print-treatment layer that permanently bonds with silver pastes, eliminating delamination risks. |
-
Chemical & Detergent Resistance: Protects against laundry liquids, softeners, and skin oils. Our film resists swelling and stress-cracking, maintaining its structural and optical integrity.
-
UV-Stabilized Anti-Yellowing: Integrates efficient UV absorbers to delay polymer degradation, preventing yellowing or brittleness over years of sunlight exposure near windows or balconies.
-
Hard-Coated Scratch Resistance: We offer specialized hard-coated versions (2H–3H surface hardness) to combat micro-scratches from fingernails, buttons, or rough cleaning cloths.
-
Class 1,000 Cleanroom Production: Extruded and coated in dust-free workshops with online optical defect inspection to eliminate dust particles (>0.1mm) and ensure "zero-defect" visual quality.
Available in both master rolls and precision-slitted sheets to fit your exact production line:
-
ThermoStable™ (Low-Shrink Series): For complex capacitive touch panels requiring multi-layer silver circuit printing.
-
ArmorCoat™ (Hard-Coated Series): Eliminates secondary hard-coating processes for premium glossy control panels.
-
SunGuard™ (UV-Resistant Series): Engineered for outdoor or high-sunlight laundry environments.
Certified to ISO9001:2015 and ISO14001, our materials are fully compliant with RoHS 2.0 and REACH standards. We understand the strict requirements of global appliance lifecycles and offer robust batch-to-batch consistency. Whether you require a 1,000 sqm trial order with flexible advance payment terms or high-volume monthly shipments, we provide comprehensive technical and print-compatibility support.
