Rare Earth NdFeB Rubber Magnet Rustproof Rubber Magnet Sheet Rubber Magnet Strip

Flexible NdFeB Rubber Magnet

Process flow

1. Use NdFeB magnetic powder, CPE and antioxidant to mix in a closed mixer, and then crush into particles
2. Produced by calendering or extrusion into materials that require thickness and diameter
3. UV varnish or PVC and PET paste
4. Magnetization, testing, packaging

Application

The magnetic properties of rubber NdFeB magnets are the highest among the current rubber magnets, which can be widely used in machinery, medical equipment, outdoor advertising display purposes, and can also be used in household appliances and toys.
