Magnetic elastomer

Description

HOLDING FORCE

  • Magnetic force is optimal when the magnet is in contact with a mild steel frame, flat, clean and rather thick. It is lower with allied steels and cast iron (less 30% for cast iron).
  • It is lower in the presence of an air gap (space between the part to magnetize and the polar face of the magnet).
  • It is decreasing by 0,4% every degree C (see besides curve). It is reversible within the limit of working temperatures of the material.

INDUCTION ON SURFACE

  • The maximum value of induction in surface is about 600 Gauss. This value is decreasing by 0,2% every degree C when temperature is increasing. This loss is reversible.

MECHANICAL RESISTANCE

  • Flexible rubber magnets offer large resistance to shocks. They easily can be cut with usual cutting tools (scissors, massicots, stamps, drills…)

RESISTANCE TO CHEMICAL AGENTS

  • Contact with petrol, acetone, benzene, mineral oil and chlorinated solvents must be avoided.
  • Sticking is advised with a neoprene, epoxid or cyanoacrylate glue.

USE ON CAR-BODIES

  • It is necessary to apply the varnished side on the car-body. Before to use magnetic sheet or strip, the car body must be cleaned to avoid any scratch.
  • We don’t recommend to use magnetic rubber products on metal sheets with air-dried paints, such as touch-up paints for car bodies.

HANDLING INSTRUCTIONS

  • Magnetic rubber can have a shrinking of about 3% on the length (to be taken into account for precision cuttings).
  • Adhesive executions must not be stocked over one year.
  • Keep away from heat and sun.
