Polypropylene-based composites filled with multi-wall carbon nanotubes (MWCNTs), ranging from 1 to 6 wt%, were obtained by injection molding from a previous masterbatch compounded by twin-screw extrusion (TSE). Resultant electrical percolation phenomenon was related to the ultrathin structure of the carbonbased fillers and the high dispersion achieved in the thermoplastic matrix. In particular, conductivity experiments showed a threshold value of 3 wt% (1.3 vol%) of MWCNTs for percolation to occur. Electrical percolation was achieved as a result of the formation of an interconnected three-dimensional structure compromising a top average inter-nanotube distance of about 493 nm among isolated nanotubes in polypropylene. The current work is hoped to bear significance toward understanding of the electrical performance for industrial ultrathin carbon black-based polyolefin composites.]]>

0 A new polyfunctional flame retardant masterbatch for XPS foam industry /feijoogo/presentacion-ami-2013updated presentacionami2013updated-140502055829-phpapp01
A new masterbatch technology for the use in XPS foam insulation panels is described. These new special additives make possible to obtain XPS insulation panels with lower values in thermal conductivity (λ value), increase in compressive strength properties and a better density profile across their thickness. All these properties are achieved by means of a reduction of the average cell size in the 25-65 % range as a consequence of the use of novel nucleating/reinforcing clay particles, which have a favorable interaction with CO2 blowing agent. Additionally, a new synergistic effect of a flame retardant organic molecule/clay is presented as a REACH compliant alternative to hexabromocyclododecane (HBCD). This new family of masterbatches is presented under the INNOVEX® trade registered name. The products here described are particularly focused on the insulation materials industry.]]>

High-barrier packaging can significantly reduce absorption, desorption and diffusion of gases and liquids to maintain the quality of food. This paper provides technical information on the barrier properties of a new solution based on a passive non-nanosized technology for its use in polyolefin materials. This is interestingly presented as a novel alternative to other new commercial passive fillers such as unmodified or organically modified nanoclays. In particular, the new additive offered better barrier performance during sterilization conditions, in which the water vapor permeability was reduced to about 60% when compared to the unfilled polypropylene film. Ferro, a leading supplier of specialty plastics, has recently developed OPTUM® Barrier masterbatch for a wide range of polymers. This can be incorporated by melt processing in most of the manufacturing processes involved in the developing of single and multi-layer structures in flexible and rigid packaging. In particular this is suitable for food packaging applications in order to increase product protection and shelf-life. Barrier applications can be found, however, in other market segments such as cosmetics, industrial containers and agricultural films, where barrier to oxygen and other gases is also critical.]]>
