Kunststoffe international, 2005-11-21, Fillers: Improved Properties and Processing
Trade Fair Report Improved Properties and Processing Fillers. The trend that was obvious during the past decade continued at this year’s K-Show. The consequences of the increased price of energy, especially oil, together with developments regarding the exchange rate of the U.S. dollar, have had a significant effect on all materials, but especially the filler industry because of the very high freight costs in relation to the value of the product. Increasing transportation costs, in particular, pr...

... and, of course, the material itself. It is therefore impossible to make any general statement, even though the competitiveness of these products can be illustrated with the aid of an example [9]: - Wood fibres, specially suitable for extrusion (Lignocel P super; JRS), approx. 0.25 EUR/kg - PP approx. 1 EUR/kg and additives between 2–5 EUR/kg - The total price per kg of the composite material is thus less than 0.5 EUR/kg Thermosets and thermoplastics (preferably PE and PP) are the conventional ...

...n 2006, broken down by country [1]. Materials and Compounding Technology The following materials were used in the trials: a metallocene polyproplyene (PP; grade: MR 2002, manufacturer: Total Petrochemicals, MFR=13g/10min), wood pellets (type: Lignocel P Super, manufacturer: Rettenmaier) and coupling agent (PP-MAH; type: Licomont AR 504, manufacturer: Clariant). The wood pellets were predried in a circulating-air dryer (type: LS 50, manufacturer: Motan) to give a residual moisture content in al...

...ies of WPC, a standard commercially available metallocene polypropylene (grade: MR 2002; manufacturer: Total Petrochemicals) with a melt index (230°C, 2.16kg) of 13g/10min (manufacturer’s data) was used as the matrix material. Wood pellets (type: Lignocel P Super; manufacturer: Rettenmaier) were used as the wood fibre component. The wood pellets were compressed wood fibres in pellet form with a diameter ranging from about 3 to 6mm. They consisted of soft wood fibres with a length varying between...

Moreover, coarser wood particles and a finer wood flour (type: Lignocel 9 and Arbocel HW 630 PU respectively, manufacturer: J. Rettenmaier & Söhne GmbH + Co. KG, Rosenberg, Germany) were used (Table 1). The materials were compounded in advance of the trials on a twin-screw extruder (type: ZSE 18HPe, manufacturer: Leistrit...
