Pellets
EMC/EMI absorption pellets merge NANOMAG magnetic powders (MnZn, Fe₃O₄...) with tailored polymer matrices. The powders supply electromagnetic properties, in order to optimize permeability, permittivity, reflectivity and also reflection loss, while the polymers provide the mechanical performance the application demands, like flexibility, rigidity, heat resistance...

Infinite Formulation Possibilities
Whatever polymer platform or electromagnetic profile you require, silicone elastomer, epoxy resin, conductive paint, technical ink, and beyond, we formulate it.
Our team fine-tunes every variable (viscosity, magnetic-filler loading, cure kinetics, rheology) until the compound meets every line of your specification sheet.
Present the challenge, and we take it from concept formulation to the finished, ready-to-use material.
What about HYMAGIN?
HYMAG'IN produces and sells several ranges of innovative ferrite-based magnetic materials.
The products are ultra-fine powders and semi-finished products for additive manufacturing, such as magnetic filaments for 3D-printing, used to solve electromagnetic compatibility (EMC) problems, mainly as microwave absorbers.
