Problems solved by technology

However, the hardness of graphite is low and it is easy to wear and tear. Only using graphite as a lubricating component is not conducive to maintaining long-term lubrication and anti-friction performance, and the effect of prolonging the service life of rubber products is limited. It is necessary to improve it
