Rubber Magnet
Product overview
Rubber magnet is a composite material made of ferrite magnetic powder mixed with rubber raw materials. The finished product is made by extrusion or rolling. Due to its high plasticity, the finished or semi-finished products can be cut, punched…

Product overview
Product overview
Magnetic assemblies are the assemblies of magnetic materials (NdFeB, Samarium Cobalt, etc.) and metal and non-metal materials through bonding, injection molding and other processes, such as EPS upper rotors, wind power magnetic poles, motor stators and rotors, linear motor assemblies, sensors, etc. Magnetic assemblies’ products are the extension of Earth-Panda to the downstream industrial chain of magnetic materials, reducing assembly time and manufacturing cost for customers.
Main overview
- 1. Rubber ferrite permanent magnet: It is the composite magnetic material prepared through certain processing process by using high-performance strontium ferrite magnetic powder as filler, rubber organic compound as adhesive and adding rubber-plastic auxiliary agent.
- 2. Flexible NdFeB: Rubber NdFeB permanent magnet is a kind of new flexible bonding permanent magnet material. It is a composite material prepared by the production process of rubber products with rubber organic compound as binder, rapidly quenched FeB powder as filler and adding auxiliary processing additive.
- 3.Iron rubberized fabric/iron powder adhesive: iron rubberized fabric is a composite iron material prepared by certain processing technology with reduced iron powder as filler, rubber organic compound as adhesive and adding rubber-plastic auxiliary agent.
