Product Overview
The VMANX Automotive Touch Film Sensor utilizes "Precision Electronic Printing Technolog"· Employing high-stability PET film as the substrate, combined with a multi-layer screen-printedstructure of silver conductive circuits, protective carbon layers, and transparent conductive ink(PEDOT:PSS). topped with a high-performance Optically Clear Adhesive (OCA).This product innovatively integrates custom-printed patterns with transparent capacitive sensingelectrodes, achieving a balance of functionality and aesthetics. Designed for demandingautomotive electronic environments,it meets automotive-grade reliability and eco-compliancestandards.
Integrated Visual & Touch Design
Custom patterns/logos (e.g., backlit icons, brand logos) can be directly printed on PET film,Simultaneously, the highly transparent PEDOT:PSS layer (transmittance >85%) enables precise capacitive touch sensing
Automotive-Grade Materials & Processes
Substrate: High-strength, temperature-resistant PET film (standard thickness: 125um; options: 100um/188um).
Circuit Structure :Precision-printed silver conductive traces + protective carbon layer, ensuring superiorconductivity, oxidation resistance,and mechanical durability.
Transparent Electrode :Screen-printed PEDOT:PSS conductive ink, offering high transparency and stable conductivity.
Optical Lamination: High-transmittance, low-haze OCA with vacuum lamination for bubble/wrinkle-free performance.
Exceptional Environmental Resilience
Wide Operating Temperature : -40°C to +85°C (extendable to +105°C upon request).
High Humidity Resistance : Stable operation at 95% RH.
Weather Resistance : Passes UV aging, damp heat, thermal shock tests-no yellowing, cracking, or performance degradation.Chemical Resistance: Withstands automotive cleaners, sweat, oils, etc
Longevity :>10-year lifespan (per typical automotive use); validated via vibration, shock, and bend tests.Environmental Compliance
Meets VOC emission standards (e.g, GB/T 27630, VDA 270, ISO 12219) for cabin air quality.
Complies with RoHS, REACH, and other international regulations.
