Inside surface treatment of Rotationally Moulded Insulated Boxes, containers and Tubs with eltech ozone system provides perfect bonding between plastic surface and PU hence improve insulation quality and bonding inside surface treatment of Rotationally Moulded Insulated Boxes, Containers and Tubs is very critical. It is possible with eltech ozone . Eltech has developed surface treatment system to treat inside plastic wall of tiny boats, insulated plastic cooler boxes, insulated fish cooler boxes, insulated surfboats, etc. products that consist of fiberglass on the outside and foam on the inside also called sandwich construction.
Polyeurathane foam on the inside and glass fibre plastic on the outside are referred to as sandwich construction. With a traditional chemical process, PU foam does not adhere to the interior of plastic surface, resulting in an unsatisfactory and uneven result as well as additional chemical expense. Eltech Surface System will significantly reduce adhesion issues without the use of chemicals. Concentrated Ozone gas which is blown into the shell and is left inside for a while before it is sucked out again. Thereafter the Polyurethane Foam is injected. It then hardens and adheres to the inside of the shell.
