SGL’s business units Composites – Fibres & Materials (CFM) and Graphite Materials & Systems (GMS) will exhibit on a joint booth at this year’s Fakuma plastics trade fair on 17-21 October in Friedrichshafen, Germany,
The CFM business unit will showcase established products such as short and milled carbon fibres, as well as semi-finished products based on carbon and glass fibres with a thermoplastic matrix. The foundation for these thermoplastic composites are 50k carbon fibres, with a size tailored for thermoplastics. Unidirectional (UD) tapes help reinforce components based on the load path. Organo sheets can be customised by selecting a specific structure of UD tapes, rovings, fabrics or nonwovens. Tapes and organo sheets can also be processed in thermoforming processes. For additional reinforcement through injection moulding, SGL also offers long fibre reinforced thermoplastic granulates (LFT).
With the help of a demonstrator, SGL will present several examples for combining thermoplastic composite materials. Among them the latest developments in the area of thermoplastic profiles, which can be used in combination with injection moulding for local reinforcement.
The GMS business unit will present products for increasing the thermal conductivity of plastics. SIGRATHERM GFG powder, produced from expanded natural graphite, is said to offer advantages when used as a plastic additive even at low filler contents thanks to its high purity, large specific surface and low bulk density. SGL reports it can increase thermal conductivity significantly while only minimally affecting other characteristics of the polymer. Its good free flow properties and dosability allow economic processing, even on a large scale, the company says. In addition to increasing thermal conductivity, the additives can also be used for electrical and antistatic applications.
