BASF presents new concept refrigerator coolpure 1.0

According to the company, coolpure 1.0 opens up new fields of application for polyurethane in the refrigerator sector, where the emphasis until now has been mainly on insulation. These fields are joined by ideas for new design. The refrigerator concept is a blend of innovative materials and functionality with modern design, a futuristic formal language and the use of sustainable materials. Rather than produce refrigerators itself, BASF says it aims to demonstrate with cutting-edge designs all that is possible with PU as a material. Transcending the bounds of pure insulation, it is capable of inspiring refrigerator manufacturers to develop new approaches. [image_0] Finishes with Permaskin compounds
Compounds for the production of white, throughcolored films based on TPU for the finishing of three-dimensional components: They protect surfaces and are suitable for a variety of substrates such as wood, metal and plastic - and also PU rigid foam. They can be applied to different surface textures and geometries as well. Even complicated contours like those of undercuts, drawer handles and pulls are possible. It is also possible to back-print these transparent films with wood-grain or technical finishes. In addition, they display high durability, says BASF. The solvent-free production process generates only minimal set-up costs and comprises just a few steps. On the new coolpure 1.0, both the exterior and interior surfaces, including the bottle rack, are coated with Permaskin. This offers designers the chance to develop new, high-value formal languages, says the company. [image_1] Low-energy, soft light with a flexible optical waveguide
The interior lighting and the external light strip (ambient light) have been realized with a flexible optical waveguide made of Elastollan. The use of special aliphatic isocyanates yields crystal-clear products that dim the light only minimally. Thanks to its flexibility, Elastollan offers greater design freedom in terms of form and color than other materials and adapts with ease to any contour, says BASF. By printing reflector areas (inkjet) or by texturing the surface, it is possible to achieve controlled light effects. [image_2] Optimized insulation with VIP fixation
With refrigerators and freezers having to meet rising standards of energy efficiency, they need ever-better insulation. This is where vacuum-insulated panels (VIPs) represent a good solution, says BASF. However, their application with adhesive tape - the conventional method - is anything but ideal; until now it has only been possible to apply VIPs manually to level surfaces. Balindur is a novel solution to this problem, as the PU foam for fixing the panels is not only adhesive, but also compensates for unevenness in the substrate. VIP panels can thus be attached with ease to the side walls and particularly to the inliner of the fridge door. VIP fixation stops the VIP panels becoming visible on the outer wall and prevents delamination. What's more, by positioning the VIPs on the inliner, it is possible to improve the refrigerator's or freezer's energy efficiency by up to 4 %. Balindur thus also facilitates greater design freedom and more flexible production processes. Thanks to its low density and high compression resistance, Elastopor H, an open-cell PU foam, is particularly suitable as the core material for VIPs. It can be produced in contoured panel form and is easier to process than other basic material. The PU rigid foam is also simple to recycle - a genuine advantage and also a valuable contribution to the environmental and cost profile of VIPs. Elastocool Advanced for higher productivity
A new generation of familiar PU rigid foam systems - Elastocool Advanced achieves good results with its enhanced properties, says BASF. Its thermal conductivity has been reduced yet again, which means another cut in energy consumption. However, Elastocool Advanced shows its strengths mainly in production with a significant reduction in demoulding time. This boosts the capacity of the foaming line and adds to the flexibility of the production process. The system's compression resistance has been additionally enhanced, thus making it possible to reduce density and hence the input of material. Immaculate profiled seals made of Elastollan
BASF Polyurethanes produces thermoplastic polyurethanes with good hydrolysis resistance and cold flexibility and resistance to microorganisms for the extrusion of profiles and seals. The profiles, which dispense with plasticizers, can be used in continuous seals and represent a genuine alternative to conventional materials, says the company. Soft-touch TPU door handles
A special material is extra-soft, aliphatic Elastollan, a lightfast TPU with good flow that permits true-to-original surface replication. Highly light- and colorfast, it displays an agreeable soft touch and renders additional coatings superfluous. It also shows good resistance to abrasion and scratches as well as to external aggression in an abundance of forms. The outcome is a high-grade surface, with a combination of high functionality and exceptional design scope. According to the company, from now on it will be possible to create an own unique and unmistakable surface touch for each appliance. High-transparency shelves made of Elastollan
Shelves made of thermoplastic polyether polyurethane are distinguished by their hydrolysis resistance and cold flexibility combined with high stiffness and resistance to microorganisms. In addition, they come with high transparency even in high wall thicknesses and an abrasion- and scratch-resistant surface. And then there's an extra optical effect, as the shelf lights up with light from rear-mounted LEDs, which is emitted at the cut surfaces. Seat elements made of Elastofoam I
With both its flexible and elastic properties, Elastofoam I delivers remarkable sitting comfort, says BASF. These properties can also be varied to suit the requirements of the application. The PU system has a pleasant feel and displays good skin formation while also being abrasion-resistant and long-lasting. Incidentally, thanks to its good flow, the system is also capable of replicating complex textures - design freedom is thus assured. Seating elements in virtually any shape and color transform a purely functional refrigerator into an impressive piece of furniture. Window Spray Technology
Another feature can be found in the lid of the freezer drawer: Window Spray Technology, also known by the name of Colo-Fast WST. A glass encapsulation material that has already become established with many manufacturers of glass panes and modules. According to BASF, the perfect system for pressure-less application on glass in the open mould - with an impressive flush finish of seal and glass. It makes Colo-Fast a seal and surround in one.
