Rubber Magnets
Rubber magnet is divided into homogeneous and heterogeneous, which is made by adding magnet powder and various matching agents in rubber through dense refining, calendering vulcanization and withdrawal vulcanization. It has good flatness and brightness, good abrasion resistance and high pressure resistance; the color is black, dark coffee, white, etc., thickness 0.3-10mm, width 5-600mm, length can be slit or rolled according to actual needs. Widely used in door and window sealing strip, toy industry, advertising industry, car instrument, refrigerator sticker, auto 4S4 repair store and other occasions.
