Pure aramid paper
Features:
1. The structure is dense and the surface is smooth. Compared with the laminated aramid paper of the same thickness, it has higher tensile strength and tear strength.
2. It has excellent high temperature resistance, can be used at a high temperature of 210 °C for a long time (above H level), and has passed the UL relative temperature index (RTI) certification
3. It has excellent flame retardant performance, less smoke and no droplet during combustion, and self extinguishing when take it way from fire.
