Extrusion International 5-2018

41 Extrusion International 5/2018 plasticWOOD works in full awareness and respect for protection and safe- guarding of the environment. We look for those, like us share this concept by creating innovative, ductile and sus- tainable product for the market. For this reason we combined natural fibers with thermoplastic polymers creating unique compounds. The wood that we use come from selected production scraps avoiding any tree-chopping. We usually use fir wood flour, al- though our interest in research and development has lead us to also test rice and corn straw, apple peel pro- duction waste, olive stones and many other vegetable fibres available in the agricultural sector, which being waste productsmakes the LCAof our product evenmore positive. This wood type having been selected for its very light colour, which makes it possible to assure production continu- ity, avoiding colour variations of the natural fibre as much as possible. ing technologies for traditional ther- moplastics. In addition unlike the composites with mineral fillers, the plasticWOOD compound minimize the wear of the machinery. To obtain a very good result we suggest a drying pre-treatment process before pro- cessing in order to improve the final aesthetic effect and to avoid any sur- face scarfing, caused by any eventual humidity residue. The sole critical vari- able during the moulding stage is the temperature, which is not adjusted correctly, may result in a considerable change in the colour: the natural com- ponent in fact tending to degrade and darken. plasticWOOD The green concept for extrusion and injection moulding plasticWOOD.it Srl www.plasticwood.it Hall B2, Booth 2123 It is important emphasize the com- plete recyclability on the production chain of our compounds. One of our focus is to produce solution that re- spect the environment. What shape has innovation? The one you want..Our secret? The know-how to dose the right ingredients to make products with alternative tactile and aesthetic fellings. Our products have something more compare to tradi- tional thermoplastics. The percentage of wood which enriches the polymer allows to obtain original and natural finishing, together with the finished product scent. WPC products have the qualities of wood, without the defects: so that these materials are particularly appreciated for their re- sistance to the elements, corrosion and mould, and for their capacity for retaining their mechanical properties through time. It is important to consider that our compound fits your existing process- plasticWOOD WPC PHYSICAL PROPERTIES Specific weight at 23 °C ISO 1183 31,064 g/cm 3 MVR index (190/10) ISO 1133 10-29 cm 3 Water absorption D1037 (ASTM) less than 1% MECHANICAL PROPERTIES Flexural modulus (2 mm/min) ISO 178/A/2 3,490 MPa Flexural yield 60 MPa Tensile modulus (ISO 527-2/1A/1) 1,740 MPa Maximum load 32 MPa Deformation at break 5% Charpy test without notch at 23 °C ISO179-1 1 and KU 13 m 2 MOULDING CONDITIONS Press head temperature approx. 160 °C; Temperature on the injection point approx. 175-180 °C; Mould temperature control range 40-60 °C; Screw temperature approx. 160/165 °C Ther formance ILLIG.de
