Flat thin flexible rubber magnet sheets
Flexible Magnet is made by high quality ferrite magnet powder and thermo plastics, This product is lead from using strontium ferrite. It do not contain any heavy metal or hazardous chemicals. This type of rubber magnet has the best flexibility characteristics of any permanent magnetic materials. It can be easily folded and twisted without damaging the magnetic property of the magnet. It also has excellent machanibility and can be easily drilled, punched, scissor cut, knift cut and die cut.
Flexible Magnetic Sheeting is produced with calendering process. It is normally used in office appliance, advertising, checking and testing meters etc.

Material Thickness of rubber magnet sheet
The popular thickness range of flexible magnet material is 0.4-1.5mm, but thicker material is available in high energy. The thicker the material the greater the pull. It is not in direct proportion, but the thicker the material the greater the pull increase.
Eg:0.75mm thick material has a pull of 44 gram/cm2 and if proportional the 1.5mm thick material would be 88gram/cm2, but in fact it is actually far higher at 140 gram/cm2.
