Polycarbonate honeycomb is a thermoplastic material available in different sizes, thicknesses, colours and cells diameter. It’s used mainly for laminar-flow ventilation, commercial refrigeration, sterilized rooms, wind tunnels, and climatic chambers.
Honeycomb deflectors increase air flow efficiency and efficacy. Moreover, they eliminate turbulence, reduce impurity, humidity, and noise and energy consumption.
In lighting industry, black polycarbonate honeycomb is used as grids in front of led lamps to trap the peripheral light.
Polycarbonate honeycomb with density of 200kg/m3 is also an excellent crash-absorber. Cel’s polycarbonate honeycomb has established new standard as far as energy absorption is concerned. In fact, the uniform crushing of the cells absorbs kinetic energy at a constant compressive load until a 78% reduction of its initial volume. We supply special densities, according to the level of energy absorption required by the costumer.
We can supply two types of polycarbonate: standard quality polycarbonate and visual grade polycarbonate.
In the visual grade polycarbonate the positioning of the cells is checked one by one in order to obtain an outstanding quality product. For this reason its supply is related to higher costs.
In standard quality we provide a product of an excellent quality but where sometimes a cell might be missing. This does not affect its use at all, as long as it is not that of lighting.
Lighting customers are therefore asked to require a visual quality product.
