Applications

MagniF is a high‑density, high‑purity product with thermal and electrical conductivity. It is used in applications that require dense or ferrimagnetic additives and therefore serves as a functional filler for polymers and coatings across multiple industries.  Key applications include:

High-density Polymer

• Serves as a functional filler for polymers in a variety of high‑density applications.
• Compounding polymers with MagniF is straightforward, as it behaves isotropically and has a low influence on viscosity.

Detectable compounds

• Incorporated into plastic formulations to create magnetically responsive components.
• Used in precision applications such as sensors and industrial automation.

Brake pads (optimal for cold friction)

• Improves friction stability and increases wear resistance.
• Act as a solid lubricant to reduce excessive wear and heat.

Sound‑damping polymers

• Filled compounds can be extruded into very high‑density parts with excellent surface finish.
• Polymer components are widely used in the automotive industry to reduce engine noise transmission into the cabin.

Magnetic paint

• When incorporated into wall coatings, chalkboard paints, or furniture coatings, magnets are attracted to the coated surface.
• As a magnetic paint additive, it offers the advantage of being non‑rusting compared with iron‑powder‑based fillers.

Water treatment

• Applied in wastewater treatment for removing heavy metals and magnetic separation processes.
• Ensures efficient contaminant removal while allowing for material recovery.

When MagniF is added to polymers and coatings, it enhances both performance and appearance. It helps reduce noise and vibration, making materials quieter and more stable in use. Its higher density adds a sense of strength and quality while also improving the product’s overall appearance.

Because MagniF is ferrimagnetic, materials containing it can be attracted to magnets and detected by metal detectors—useful for safety, quality control, and recycling applications. MagniF also has the ability to absorb microwave energy and convert it into heat, offering unique possibilities in specialised manufacturing and electromagnetic applications

Mineral information

MagniF is manufactured from the natural mineral Magnetite, mined in our own group resources. The LKAB mines are located in Malmberget in the northern part of Sweden.

MagniF toxicology

The product is harmless to the environment and non-toxic in all its forms.
