Key Features

1. Outstanding High-temperature Stability: It can maintain stable physical and mechanical performance under extreme high temperature up to 200°C, avoiding brittleness or degradation during long-time hot pressing process, far exceeding ordinary kraft paper.

2. Thermal Insulation & Pressure Buffering: It provides effective thermal insulation to uniform heat distribution, while buffering high pressure to ensure uniform pressing for PCB boards, and absorbing volatile matters during the process.

3. Surface Protection & Release Performance: It prevents scratches on the PCB surface, while avoiding adhesion between PCB and steel plates after pressing, enabling easy release of workpieces after the process.
