1. Using flexible graphite as the base material and adding reinforcing agents to make it thinner yet stronger;
2. Raw materials undergo purification treatment, resulting in higher purity and improved durability;
3. By adopting new material technologies, we have significantly boosted mass production capacity while reducing costs.
