    CO-EXTRUSION

    The production technology that makes our sheeting solutions unique

    Co-extrusion is a manufacturing process based on the transformation of a plastic substrate layer, involving the simultaneous processing of different components so that they emerge from the production machine in the form of layered bonded sheets that combine the best features of the constituent composing materials.

    The Tecno Imac production stations are organised in units of three extrusion machines. In each extrusion machine, the composing mixture components (resins, plasticisers, stabilisers, pigments etc.) are fed through hoppers into a cylindrical chamber. Here the mixture is heated and compressed with worm screws s until it reaches the co-extrusion flat head where the layers, created by the individual extruders, converge to form a coarse sheet. This is then laminated in a calendering press and it is shaped into the final profile.

    MATERIALS

    Over time, the thermoplastic co-extrusion process patented by RENOLIT Tecno Imac has sustained the production of sheeting materials with increasingly higher performance. Since the creation of the Polimglass®, patented in 1992, the technology evolution and the availability of new engineering plastics drove further development and the emergence of new materials based on the coextrusion of three layers, such as Ecotres®, which is the base material for making ECOLINA®, GRECOLINA® and ECOLTHERM sheeting as well as their relative accessories, as well as HSP® (High Strength Polymer), from which the new line of IMACROOF® is made.

    All these materials have a common production process that, with different chemical formulations in the various layers, consists in the process of conveying different types of thermoplastic materials prepared in three different extruders into a single extrusion head. The result is a single sheet that is stratified in three different layers, each of which has specific features designed to perform certain functions:

    1-top layer: solid-coloured in PMMA (Methacrylate) for colours and finishings that are perfectly and highly resistant to UV-rays, to meteorological conditions and to exposure to chemicals of any kind.

    2-middle layer: a mixture of different polymers loaded with micronized inert material, for a low thermal expansion, good acoustic behaviour and resistance to bending.

    3-bottom layer: thermoplastic compounds for maximum resistance to impact and chemical aggression from underneath.

    The result of this particular combination of thermoplastic materials is a stable and resistant synthetic product, applicable to any environmental situation, without fear of attacks of acid vapours of any kind, whether industrial or agricultural, or the most aggressive saline environments.
