Vacuum Insulation Panels

State-of-the-art refrigerators feature improved energy efficiency. Their lower energy consumption is beneficial for the environment as well as the customer’s monthly electricity bill. One feature that enables manufacturers of modern fridges to produce such green appliances is the so-called vacuum insulation panel (VIP or VIP panel). These panels offer outstanding insulation properties compared to non-evacuated conventional insulation materials due to their evacuated insulation. Furthermore, VIPs also allow the housings of cooling appliances to be narrower, which gives the consumer more space for storing food and beverages.

Vacuum insulation panels need to be attached in the sidewalls and doors of refrigerators and freezers. One of the best solutions is to bond them to the surface with a double-sided tape. To avoid polyurethane foam (which completes the filling later on) getting in between the bonding and lifting the panel, the tape needs to cover the full area of the VIP. Otherwise, the excellent expanding properties of the PU foam, in combination with the vacuum insulation panel, could lead to visible deformation of the sidewalls and doors.

tesa offers solutions especially developed for this application that fulfill all demanding requirements. Appliance manufacturers can choose from an assortment of tesa double-sided non-woven tapes. The tapes’ high initial tack and sufficient adhesion values allow for fast and stable production processes, while also guaranteeing excellent quality in the end product.
