PTFE coated magnets feature a low-friction, non-stick surface that resists chemicals, moisture, and contamination. This makes them ideal for laboratory, medical, and food-processing environments where cleanliness and chemical compatibility are key.

Available in a range of sizes and grades, PTFE coated magnets are used for stir bars, cleanroom applications, and assemblies where easy release and corrosion resistance are essential.

Frequently Asked Questions

Are PTFE coated magnets FDA compliant?

PTFE is widely used in food and medical applications, but verify compliance with your specific regulatory requirements.

What’s the difference between molded PTFE coated magnets and spray-coated PTFE?

Molded PTFE coatings are compression-formed around the magnet, resulting in a thicker, more uniform, and durable layer with excellent non-stick and chemical resistance — this is what we carry in stock. Spray-coated PTFE is thinner and less robust, offering a lighter coating option for some applications but with reduced abrasion resistance.

What temperature range can PTFE coated magnets withstand?

PTFE coatings typically handle temperatures up to around 250 °C, but it is important to check the underlying magnet grade temperature limit. If you have questions please contact our experts to discuss your specific application.

Are PTFE coated magnets non-stick?

Yes, PTFE creates a slick, low-friction surface, ideal for stir bars and applications where easy release is needed.

Can you produce custom sizes, magnetization direction or coatings?

Yes. Through our engineering division, SM Magnetics, we can design and manufacture custom sizes, magnetization directions, and specialized coatings. You can either submit a custom request form or contact us directly to speak with our experts.
