In the beginning the thermal insulation between refrigerator door and cabinet was ensured by means of tube-shaped extruded profiles made of vulcanized rubber and welded together by using filling materials, which are squeezed in between the closing frames by a ratchet closure mechanism.
ILPEA designed and manufactured a sealing system that used a PVC compound gasket profile with no plasticizer migration, which, thanks to the insertion of a flexible magnetic strip inside the gasket, allowed the perfect closing of the door, thereby overcoming the need of a ratchet closure. This solution has dramatically changed the concept of thermal insulation in the refrigerator and freezer sector and has allowed ILPEA to reach a position as worldwide market leader . The company is constantly researching new and groundebraking solutions and has developed four main product lines.
