Product Description
White Rectangular CCL Buffering Pad
High-performance replacement for hot press kraft paper with superior dimensional stability (±250ppm tolerance) and extended service life of 600-800 cycles.
Product Overview
CCL cushion pads are essential buffering materials designed specifically for copper clad laminate (CCL) lamination processes. These rigid red pads significantly improve dimensional safety and stability while enhancing production efficiency.
Key Advantages
- Extended service life: 600-800 press cycles for significant cost reduction
- Superior dimensional stability: Achieves ±250ppm tolerance
- High temperature resistance: Up to 280℃ without carbonization
- Excellent buffering effect and thermal conductivity
- Flame retardant, non-toxic, odorless, and dust-free
- Replaces multiple sheets of hot press kraft paper with single pad
