HY-SiO3H-2 High-Fastness Luminous Silicone Heat Transfer Film
This product is a high-density, high-fastness luminous silicone heat-transfer film that combines safety warning functionality with decorative appeal. Manufactured using screen-printing positive-transfer technology, this film incorporates high-performance luminous pigments within a durable silicone matrix and a hot-melt adhesive layer. It absorbs ambient or artificial light and emits a sustained afterglow in darkness. Compatible with CNC cutting and die-cutting, it enables custom designs with fine detail, effectively enhancing the visibility of textile products. The film is widely used in safety workwear, outdoor gear, stage costumes, and fashion apparel.
Printing Color Performance
Key Features
- Outstanding wash and abrasion resistance – robust multi-layer construction withstands 20 cycles at 60°C without delamination or degradation.
- Precise cutting capability – reproduces fine details down to 1.0 mm text or line width, replacing costly mold-silicone processes.
- Long-lasting luminescence – delivers over 4–8 hours of discernible afterglow in dark environments after standard light excitation (initial brightness >2.0 mcd/m² after 20 minutes of charging).
- Safe and eco‑friendly – free from radioactive substances and hazardous heavy metals; fully compliant with environmental standards.
- Multi‑colour options – inhibits customisable glow colours for diverse design needs.
- Compatible with CNC engraving – adapts to complex pattern cutting with high precision.
- Simple heat transfer process – works with standard flatbed heat press machines, ensuring easy and consistent application.
- Anti‑sublimation performance – inhibits dye migration from dark substrates, ensuring sharp, lasting graphics.
- Versatile applications – ideal for safety workwear, outdoor equipment, stage costumes, and fashion apparel.
