Mixing by CR322 and CM140B, the workability of mixed rubber and thermal endurance performance and oil resistant performance of the surface and cured rubber are all improved.
Thus obtained was a high performance getter strip with high specific surface area, high resistance of thermal shock and good endurance of mechanical vibration.
