The test scores show good values for tensile strength, Young's modulus, flexural strength and flexural modulus, which were slightly higher than standard polycarbonate. Polymaker will be presenting a wide range of materials for 3D printing, ranging from high-performance plastics to unique aesthetic solutions, at booth number F44 at TCT Asia, the 3D printing trade show in Shanghai, China, from May , At the trade show, Covestro and its additive manufacturing business, including the newly acquired business from DSM, will be exhibitingon two booths as both had registered separately prior to the transaction.

Visitors to the trade show are invited to visit Covestro at booth number E46 and the former DSM AM at a at booth number C48 to learn more about the company's broadend product portfolio. With sales of EUR Business activities are focused on the manufacture of high-tech polymer materials and the development of innovative, sustainable solutions for products used in many areas of daily life.

In doing so, Covestro is fully committed to the circular economy. The main industries served are the automotive and transportation industries, construction, furniture and wood processing, as well as electrical, electronics, and household appliances industries. Other sectors include sports and leisure, cosmetics, health and the chemical industry itself.

At the end of , Covestro has 33 production sites worldwide and employs approximately 16, people calculated as full-time equivalents. Polymaker is a company that produces advanced 3D printing materials specifically engineered for a wide range of applications across many industries.

At the heart of Polymaker is a large research and development laboratory which drives the company forward through constant innovation and testing.

All Polymaker materials are formulated and optimized for 3D printing while maintaining the unique properties inherent to the respective base polymer. Find more information at www. INTAMSYS is a world-leading high-tech company providing 3D printing and industrial direct additive manufacturing solutions for high-performance materials. This suggests the possibility to use this method to colour plastic materials. Opacity in thick films as well as pellets can arise by different mechanisms such as rearrangement of PC chains during solvent evaporation or thermodynamical stabilization of an opaque amorphous or partially crystalline state.

Figure 8. Scale of nm is common to both figures. The occurrence of a large spherical TGNPs agglomerate with diameter of nm and a slip line as long as nm is shown in the upper region of the image. The AFM profile analysis indicates that these structures stand up to 5 nm at maximum above the flat surface.

Further improvements are necessary to avoid thermal treatments in order to obtain corrugation free surfaces for specific applications. Conclusions This paper arose from the need to exploit the unique properties of nanoparticles, specifically in polymer composites as required by factories of polymer materials.

Optical properties of well dispersed nanocomposites at very low doping contents showed improved coverage in UV-vis spectra.

The nanocomposite film absorbs near UV radiation and, to lower extent, also in the visible range. The advantage of using a solvent to disperse thiol gold-nanoparticles into a polymer for doping is exploited in the present work; in particular we have selected to use polycarbonate since it is widely used for the construction of lenses.
