Clariant’s new reactive phosphorus flame retardants

Clariant offers a broad range of non-halogenated flame retardants under the trade name Exolit that address customers’ growing environmental awareness. The Exolit range is known for its total resin-flame retardant integrity even under harsh conditions and in sophisticated applications. The new flame retardants Exolit EP 150 (LP) and Exolit EP 200 (LP) were especially developed for application in thermosetting epoxy resins. Both products show superior performance as reactive flame retardants and can be combined with bisphenol A-based epoxy resins and epoxy phenol novolacs. Both products are easy to use in epoxy thermosets as they show a broad compatibility. In addition, Exolit EP 150 is a low-viscosity liquid suitable as a flame retardant for infiltration processes. With their high phosphorus content, these two products outperform conventional flame retardants for epoxies. Therefore, UL 94 V-0 requirements can be achieved at a low dosage of flame retardant in the epoxy system. The glass transition temperature, which is a crucial parameter in epoxy chemistry, is less influenced by the two new products. www.exolit.com

Development of natural-fibre sandwich composites

> Booth J8

Achieving lightweight solutions in the automotive industry requires substantial enhancements of many car components. This also applies to naturalfibre-reinforced composites. This is the reason why TITK is investigating the manufacture of lightweight sandwich materials with natural fibre composites. Using different processes for the manufacture of nonwovens (carding and air lay processes), semi-finished products were manufactured and optimized. Compared with conventional glassfibre-reinforced headliners, the mechanical properties of the natural-fibre composites are slightly lower. This especially affects the properties under wet conditions. In terms of composite density, competitive values in the range of 0.2-0.4 g/m³ were achieved. One major advantage of natural-fibre composites is that their texture and manufacturing are simplified in a one-step process. Their acoustic properties very much depend on how compact the materials are. The best sound absorption was achieved with composite densities between 0.3 and 0.4 g/m². The composite materials made at the lab scale were processed under industrial conditions and compressed to samples. This step made it possible to check the feasibility of the technology. Potential applications include automotive indoor parts (headliners and door panels). www.titk.de Aluminium honeycombs and panels made with it offer lightweight, compression and shear resistance, fire and corrosion resistance and the possiblity to be recycled. It is used in a lots of applications (public transport industry, nautical sector, tool machines, serigraphy, building industry, ecc...) and presented several advantages namely: - lightness - stiffness - fire resistance - compression, shear and corrosion resistance - flatness - optimal stiffness-to-weight-ratio. Regarding the aluminium honeycomb the client can choose a thickness from 3 until 300mm, a cell size from 6 until 19 mm and a density from 19kg/m³ until 84kg/m³ (the density depends on the foil’s thickness and on the cell size). www.cel.eu

Aluminium honeycomb

> Booth D55

The new Komposit technology offers materials for high-temperature applications and rough industrial environments. These products are an evolution of fibre-reinforced plastics and ceramics. The range includes high-performance plastics with a temperature resistance up to 550°C and preceramic composites with a temperature resistance up to 1000°C. The synthetic and mineral character of the matrix used for these composites protects fibres during high-temperature treatments. Their electrical and thermal conductivity can be adjusted by modifying the matrix according to customer needs. Mechanical, thermal and electrical properties can be modified using the following reinforcements: Al2O3 fibre, basalt fibre, carbon fibre, SiO2 fibre or a combination of reinforcements. In addition to being excellent thermal and electrical insulators, these products are antiadhesive and have very good mechanical strength and ductility. Preceramic composites show strong mechanical performance in hightemperature applications. The advantages of these composites include temperature resistance, thermal & electrical insulation, high torsional and mechanical strength and non-flammability. They are odourless, non-toxic and eco-friendly. This unique technology saves energy and resources. www.zlbm.com
