Key Highlights

Special Surface Appearance

Matte black finish with low gloss (75-79 GU) provides a non-reflective surface for specific applications.

Appearance and processing fit

Matte black surface texture combines aesthetic appeal with suitability for downstream processing operations.

Good shading performance

The black film has approximately zero light transmittance, suitable for structures requiring high shading performance.

Uniform color

Consistent black color throughout the film ensures reliable appearance and quality.

Technology & Advantages

Shading structures and black appearance materials for CY28YG typically require low light transmittance, color uniformity, mechanical performance, and electrical performance support.

Core Values

Shading performance:
Approximately zero light transmittance provides excellent light-blocking capability. The black film body ensures complete opacity, making it suitable for structures and applications requiring high shading performance and reliable light protection.

Appearance consistency:
Uniform black color throughout the film ensures consistent visual appearance and reliable quality. Supports appearance-critical applications requiring color uniformity and aesthetic consistency across the entire product surface.

Wide application:
Covers adhesive tape, drum surfaces, and electronic spacer applications. Offers versatile solutions across multiple industries with reliable performance for diverse material and structural requirements.

Electrical safety:
Provides stable electrical insulation performance with high electrical strength (115-146 V/μm). Suitable for insulation applications in electrical and electronic equipment, ensuring reliable protection against leakage and breakdown.

Applications

Adhesive tape

Used in tape materials requiring black shading performance.

Drum surface

Used in drum surface-related materials.

Electronic material spacer

Used in spacer structures for electronic material products.
