High Performance Fillers – Wide Range of Improvement with Small Particles!

Péter Sebö, Quarzwerke GmbH
The requirements of new and modern technical plastic are changing constantly. In most cases the required property profiles cannot be met by the polymers alone. For this reason, they are modified by a broad range of filling and reinforcing materials. High performance, functional fillers on the basis of needle-shaped wollastonite, platelet-shaped mica and platelet-shaped kaolin play a central role in this for many years. The mechanical properties are often modified with glass fibres. As fibreglass-reinforced moulding compounds are clearly anisotropic on account of the alignment of the fibres in the molten compound, they are not equally suitable for all components. The use of mineral fillers offers an interesting spectrum of new possibilities on account of their different specific features, such as morphology, hardness or surface condition. Furthermore, mineral fillers can be used also as nucleating agents or as supporter to enhance the flame resistance. Lately, new functionalities are required in addition to the traditional ones. Thermal conductivity of plastics is one of these new requirements: Electrical components with high energy density require an efficient dissipation of the heat incurred while maintaining the electrical insulation performance of the plastic material used. Thermal conductive plastics create a whole series of new kinds of applications with important advantages like straightforward mass production of complex components, e.g. injection molding or lightweight production. All important issues especially if we consider new applications in the E-Mobility area. The talk should give a general overview about fillers used in various polymers, with some examples in thermoplastics and thermoset resins, considering the topics mechanics, shrinkage and other specific modifications like increasing of the thermal conductivity and enhancement of flame resistance. As the event is some time away, we expect a quite broader range of results to be included in the lecture.

New Insights From Tailored Dispersion of Multi-Walled Carbon Nanotubes Through the Optimization of Melt Mixing Parameters during Production of Polypropylene-Based Nanocomposites

Valérie Lison, NANOCYL
One major problematic to solve with multi-walled carbon nanotubes (MWCNTs) is the control of their process of dispersion in order to avoid agglomerates. This challenge is even more difficult if the host matrix is non-polar. This work focuses on the study of processing parameters to efficiently disperse MWCNTs in polypropylene with two different approaches: direct compounding and masterbatch dilution. The relationship of achieved results of dispersion and electrical performances with the variation of processing parameters will be determined through measured electrical resistivity, agglomerate area ratio and specific mechanical energy calculations.

Statistical Optimization of Additives for Glass Filled Polypropylene Stabilization

Syed Hassan, A. Schulman Inc.
This paper attempts to optimize the additive package for stabilization of glass filled polypropylene by a comprehensive design of experiment and subsequent regression analysis. Thermoplastic materials are processed at high temperature and high shear. A product’s lifetime exposure to heat, sun light, and humidity cause severe degradation in physical performance and discoloration. Suitable additives, such as heat stabilizers, antioxidants, processing aid and light stabilizers are added to improve the long-term performance. In this study, principles of mixture design of experiment and subsequent statistical optimization of additive packages for a fiber glass filled polypropylene (PP) has been performed using Minitab® to analyze the results. Responses are considered individually to understand the synergism and antagonism that exist within additives. Two anti-oxidants (AOs), two ultraviolet light (UV) stabilizers, an acid neutralizer (AN) and lubricant (L) were evaluated. Combinations of anti-oxidants (AOs) and UV stabilizers support the retention of physical properties and help reduce yellowness after hot air ageing at 150oC up to 1000 hours. The objective of this study is to analyze the properties of tensile stress at yield, tensile strain at yield, tensile modulus, notched Charpy and yellowness index. This study also evaluates the effects of projected component levels to achieve target physical properties.

A New Carbon Black for High Jetness and Easy Dispersion

Marc Delvaux, Cabot Corporation
With standard Carbon Black, it is difficult to produce compounds with both very high jetness and outstanding mechanical properties at the same time. Therefore, in a first step, we worked on our mechanical dispersion process and achieved strong improvements on jetness and mechanical properties. In a second step, we optimized our particle’s morphology to get even better color and dispersion, resulting in further improved results. Summarized, by combining process and particle innovations, mechanical performance can be increased by up to 54% at same jetness level. Depending on the application’s needs, jetness can also be increased by up to 65%. Balancing jetness and mechanicals to an optimal combination is possible by adjusting the carbon black loading.

Mechanical Reinforcement with Cellulose Filaments

Helen Lentzakis, Kruger
Kruger Biomaterials proprietary cellulose FiloCell™ is obtained from peeling the filaments from wood fibres using a mechanical process that uses no chemicals or enzymes. Since the peeling is gentle, very thin filaments are obtained while the original length is preserved. The filaments are further surface treated without modification of the chemical structure in order to prevent hornification (agglomeration due to strong hydrogen bonds) and to produce 99.7% dried, re-dispersible filaments. The resulting filaments are renewable, non-toxic, have high surface area, high aspect ratio, mechanical strength and low density. Given these properties, cellulose filaments are a unique multifunctional lightweight filler which can be added to polymer resins as a reinforcing agent and can potentially replace glass fibers. In this work, cellulose filaments are melt-blended into thermoplastics LDPE, Nylon 6 and TPU. Cellulose filaments are shown to effectively increase the Young’s modulus and the strength of all polymer matrices. The mechanical enhancement is increased with loading level of cellulose filaments. It is shown that no compatibilizing agent is needed in order to improve the interaction between the hydrophilic filler and the hydrophobic matrix. Moreover, although one drawback of natural fiber is its thermal degradation at high processing temperature, we managed to successfully compound our cellulose filaments with nylon 6 which has a processing temperature of 230˚C. In LDPE resin, at the same weight, cellulose filaments outperform glass fibers in both tensile strength and tensile modulus. In comparison with other natural fibers, cellulose filaments have the advantage of higher mechanical performance and lower water absorption.

Facing Compounding Challenges of the Future with the RingExtruder RE©

Erdmann Michael, Extricom Extrusion GmbH
The RingExtruder consists of twelve coaxial screws which are arranged in an annulus. All adjacent screws are closely intermeshing and rotate with identical speed around their own axis. The mechanical agitation is very similar to the co-rotating, closely intermeshing twin screw extruders if only two screws are observed separately. The arrangement of the screws in a circle creates twelve melt pools. This leads to optimal conditions for an intensive axial and crosswise intermixing by mass transfer between the screw channels. The RingExtruder offers outstanding dispersion capabilities together with minimal introduction of mechanical energy. The screws of the RingExtruder have 12 intermeshing zones, which produce a flow pattern with a very high degree of elongation, which can be utilized for highly efficient and energy-saving dispersion. In consequence, improved product quality can be achieved and considerably lower product temperatures are obtained. Furthermore, the geometry of the RingExtruder offers a very high surface-to-volume ratio. Thus, a large heat transfer surface area is available. Special designs of the extruder barrels and the centre core allow for an extremely efficient cooling of the processing unit. Therefore, the RingExtruder allows to control material temperatures within defined limits in order to avoid degradation or the unwanted onset of pre-vulcanisation. Due to the splitting of the product flow into the twelve screw channels an enormous surface of the plasticized material with very small volumes is available. Additionally, the twelve intermeshing areas of the screws ensure a frequent material deflection and thus a high rate of surface renewal. This gives the RingExtruder an outstanding performance in degassing processes. The RingExtruder is used for various tasks in the field of compounding, reactive extrusion and devolatilization. Typical applications include the large-scale recycling of postconsumer PET, the continuous production of rubber compounds, the processing of shear-sensitive and/or highly filled materials as well as the manufacture of adhesives.
