Plastic Coated Magnets
A durable plastic housing encloses a powerful neodymium magnet in a plastic coated magnet. Compared to the latter, natural rubber in a rubber-coated magnet can have tiny pinholes, which may cause its performance to deteriorate gradually.
The market seems to prefer colorful plastic coated magnets over rubber-coated ones. If you're looking for high-quality and competitively priced plastic coated neodymium magnets, ALB Materials Inc is a supplier worth considering.
