Product Overview

The GL-Series represents a technological advancement in opaque polyimide films, specifically engineered to deliver 40% superior thermal stability (sustaining 500°C short-term exposure) and 35% enhanced dimensional consistency compared to conventional yellow polyimide films. With its optimized opaque black formulation, the film provides complete light-blocking protection (>99.9% UV and visible light opacity) while maintaining exceptional dielectric strength (≥7.2 kV/mm), making it ideal for light-sensitive electronic components and advanced packaging applications.

Breakthrough Performance Advantages

Advanced Thermal Performance
- Continuous operation at 300°C with 500°C peak temperature resistance
- Thermal degradation temperature exceeding 550°C
- Near-zero thermal shrinkage (<0.1%) after multiple reflow cycles
Superior Electrical Protection
- Volume resistivity >10¹⁷ Ω·cm at 200°C
- Dielectric constant 3.4 ± 0.05 (1 kHz to 1 MHz)
- Corona resistance >500 hours at 2.5 kV
Enhanced Mechanical Properties
- Tensile strength >280 MPa with elongation >80%
- Tear resistance 50% higher than standard polyimide films
- Maintains flexibility through 200,000+ bending cycles
Complete Light Protection
- 99.98% opacity across 200-800 nm wavelength range
- UV stability with <2% transmittance change after 1000 hours UV exposure
- No light leakage even at thicknesses down to 5μm

Target Applications

Advanced Semiconductor Packaging
- Light barrier for image sensor and optoelectronic device packaging
- Protection layer for light-sensitive MEMS and semiconductor devices
- Interposer and substrate isolation in 2.5D/3D packaging
High-Reliability Electronics
- Flexible circuit coverlay for military and aerospace applications
- Insulation layer in automotive power modules and battery systems
- Barrier material in medical imaging and diagnostic equipment
Specialized Industrial Applications
- Light blocking layers in optical equipment and instruments
- High-temperature masking for precision manufacturing processes
- Thermal and light barrier in energy storage systems

Competitive Differentiation

The GL-Series sets a new standard for opaque polyimide films by combining complete light blocking capability with exceptional thermal and electrical performance. Unlike conventional black polyimide films that sacrifice electrical properties for opacity, our advanced formulation maintains excellent dielectric characteristics while providing absolute light protection. The film's enhanced mechanical durability and thermal stability make it suitable for the most demanding applications where both performance and reliability are critical.
