Rubber-coated magnets are designed for use in a wide range of environments and applications. They are commonly used for mounting or holding items such as lights, cameras, fixtures, tools, and even for organizing items in warehouses, workstations, vehicles, or outdoor areas.

The rubber coating on these magnets is made from synthetic rubber, which offers significant advantages over traditional magnets. It not only provides waterproofing but also enhances damage resistance, as ordinary magnets tend to break easily. The overmolded magnet chuck ensures exceptional durability, while the rubber material improves friction, preventing the magnet from sliding on mounting surfaces.

For applications exposed to outdoor sunlight, corrosive gases and liquids, or oil pollution, our encapsulated magnets offer a reliable solution. Research spanning 12 years shows that the NdFeB magnets used in these rubber-coated versions can last over 30 years, with minimal magnetic loss even after 50 years. To further enhance their lifespan, metal parts like exposed threaded holes and bolts can undergo special anti-corrosion treatments or be made of stainless steel, ensuring long-term reliability even in harsh conditions.
Here are 10 notable features of rubber-coated magnets:
1. Good Processability
We use Santoprene TPV rubber to coat NdFeB magnets. Santoprene TPV combines the best properties of vulcanized rubber with the processability of thermoplastics, allowing the rubber-coated magnets to be made in various shapes and sizes, including round, oval, and rectangular forms.
2. Scratch-Free Performance with Santoprene Rubber Coating
The Santoprene rubber coating ensures that the magnet can securely attach to surfaces such as cars or painted equipment without causing scratches or marks. It provides strong holding power with surface protection.
3. Outstanding Performance in Extreme Conditions
These rubber-coated magnets excel in harsh environments, whether it’s extreme heat or cold, or acidic or basic conditions. They feature strong pulling force, waterproofing, corrosion resistance, and durability without easily chipping.
4. Long-Term Aging Durability
Rubber-coated magnets offer long-lasting durability with consistent dimensional stability and physical properties throughout their life. They also demonstrate excellent corrosion and rust resistance.
5. Waterproof & Corrosion Resistant
The rubber coating completely shields the magnet from air and water, preventing corrosion even after extended use. This ensures that the magnetic function remains effective over time.
6. UV and Oil Resistance
The rubber coating provides excellent physical and chemical resistance to UV rays and oils. We offer various grades, with some optimized for UV resistance, oil resistance, and overall environmental protection, which can be further customized by adding trace components.
7. Wide Temperature Range
Rubber-coated magnets can operate in a wide temperature range from -40°C to 80°C, allowing them to withstand both extreme heat and cold without compromising their performance or magnetic strength.
8. Environmentally Friendly & Recyclable
Santoprene TPV rubber is environmentally friendly and recyclable. It is widely recognized for its outstanding performance in demanding consumer product applications, making it an eco-conscious choice for manufacturing rubber-coated magnets.
9. High Tenacity & Deformation Resistance
We follow strict ISO 9001:2015 quality standards, testing both the magnetic force and the rubber’s tenacity and deformation resistance. The rubber material used in our magnets is tough, durable, and resistant to deformation.
10. Variety of Color Options
Our rubber-coated magnets are available in several colors, including black, white, red, blue, and yellow. We also offer custom colors to meet specific customer needs, ensuring that the magnets can fit various aesthetic or functional requirements.
