Use Neodymium Magnets to Replace Drilling and Welding

Which type of rubber used on rubberized magnets ?

Rubberized magnets are widely used in many industrial and commercial applications. To ensure the best performance and longevity, it is important to choose the right type of rubber for these magnets. TPV rubber offers good flexibility without losing its shape or strength. Therefore, this type of rubber is ideal for use on rubberized magnets in a variety of applications.

Which type of rubber used on rubberized magnets ?

Rubber coated magnets, they are magnets covered with rubber, so they are also called rubberized magnets. Which can be used for fastening or holding objects such as lights, ladders, instruments and other devices .  Besides, it is convenient for you to take it off to attach on another place.

When threaded with clamps and hooks, these magnets with rubber coat can be used as magnetic cable holder for wire mounting. As its name suggest, the rubber outside plays very important role in the complete part.

WZ Magnetics manufactures completely full range of rubberized neodymium magnets. At the very beginning, most of the magnets were coated with NBR or EPDM which are also the common ones for these magnets. But after a long period of experiments and tests, TPV rubber finally stands out from all of them. The excellent performance and stable properties are the main reasons that we choose them and received high praise and acceptance among our customers.


What is TPV ?

TPV is short for thermoplastic vulcanizate which is a part of the thermoplastic elastomer (TPE) family of polymers, but it is closest in elastomeric properties to EPDM rubber, combining the characteristics of vulcanized rubber with the processing properties of thermoplastics.

TPV is a dynamically vulcanized alloy consisting mostly of fully cured EPDM rubber particles encapsulated in a polypropylene (PP) matrix.

Thermoplastic vulcanizate (TPV) rubber is one option that is frequently used due to its good mechanical properties, and excellent resistance to oils and chemicals. This type of rubber also has superior weathering characteristics, making it ideal for covering magnets that will be exposed to the elements over time. In addition, TPV rubber can be molded into intricate shapes with threads molded into the outer surface for strong adhesion to the magnet surface, ensuring a strong pulling force.


Why we chose the TPV rubber and what are the advantages?

When we are in the extremely harsh environment, like in the water, oil, corrosive, torried heat or bitter cold. The normal steel pot with Nickle, Zinc or Chrome coating will easily get rusted and peeled off. Then the rubber coated rare earth magnets were born at the right moment who can manage all these problems.

The rubber coating permanent magnets are called “rubber coated” because that the rubber is just like a coat for the complete part.

Magnets and steel partsdo not have to bear the harsh weather due to well protection by out covering rubber.

Comparing with EPDM, NBR, TPV combines the features of vulcanized rubber with the processing properties of thermoplastics.  It has almost perfect performance and characters in the resistance of strong pulling force,  durable, high traction, corrosion resistant, temperature resistant,waterproof, magnets do not easily chip etc.
