0.125mm Clear Hard-Coated Diffusion Film Successfully Applied to Indian Automotive Touch Button Project

With the accelerated intelligent upgrading of the Indian automotive market, the demand for automotive touch panels is experiencing explosive growth. The local automotive supply chain imposes increasingly stringent quality standards and on-time delivery requirements on high-performance optical films.

Customer & Application Scenario

The customer for this cooperation is a well-known automotive electronics manufacturer in India. This project focuses on the application of "Automotive Touch Buttons" on central control consoles and steering wheels. The automotive environment demands exceptional ink printing adhesion, scratch resistance, and optical clarity to guarantee touch sensitivity and premium aesthetics.

Our Solution

To meet the client's strict requirements, we provided a customized "0.125mm Clear Hard-Coated Diffusion Film" and achieved a rapid delivery of 90 rolls within just one week. The technical specifications of this film are highly optimized, matching key parameters perfectly:

• Film Thickness: 100 ~ 250 μm (Precisely 125 μm for this batch)

• Light Transmittance: >90.3%

• Haze: <1.3%

• Heat Shrinkage: MD 1.2% / TD 0.5% (Prevents deformation during high-temperature printing, ensuring high yield rates)

• Tensile Strength: MD 163 Mpa / TD 180 Mpa

• Elongation at Break: MD 154% / TD 110%

Customer Feedback

After mass production, the customer reported that the film exhibits top-tier surface adhesion, perfectly passing the Cross Cutting Test at the highest industry standard of 100/100 (Pass). The printing yield rate increased significantly, delivering clear, sharp graphics with zero adhesion degradation or peeling issues.

Summary

This case demonstrates our rapid response capabilities and outstanding technical performance in the automotive optical film sector, successfully empowering our Indian customer to enhance the manufacturing efficiency and product quality of automotive touch buttons.
