Additional additives or fillers can be added to change the specific properties of magnetic compounds, such as coupling agents, plasticizers, lubricants, heat stabilizers, antioxidants and epoxy resins, and other additives. Among them:
The function of the coupling agent is to coat the surface of the rare earth powder so that the magnetic powder and the binder can be better combined.
Plasticizers have the effect of softening the resin and can increase the processability of the powder mixture during the mixing process and the pellets during the forming process.
The function of the lubricant is to adjust the fluidity of the powder mixture during the mixing process and the pellet during the forming process to facilitate demolding.
Thermal stabilizer is one of the important additives for plastic processing. Its main function is to effectively prevent, reduce or even basically stop the degradation of materials during thermal processing and use.
