ing PA6 and PA66, where it delivers high tough- ness along with the good flow required for injection moulding of complex shapes. It is particularly useful for enhancing performance of recycled PA grades for use in automotive applications. The company says Lotader 4700T can be processed as a dry blend in injection moulded PA applications, offering a cost-effective route to medium-toughness parts. It is also said to be well suited to production of parts that require a painted finish.
Carbon gains
While carbon black is often viewed more for its pigment use, Cabot Corporation says the additive is frequently used to enhance attributes of PA compounds. This is achieved through careful selection of the type of carbon black, along with its surface area, particle size, and the dispersion technique within the polymer matrix. “The automotive industry is actively exploring
paths to enhance the performance capabilities of polyamide compounds, seeking attributes like reduced odour, and elevated heat stability, notably Long-Term Heat Stability (LTHS),” says Dominique Strassler, Global Segment Manager
Plastics within Cabot Corporation. “Regarding LTHS, certain carbon blacks, added to the formulation for UV protection, tend to interact with antioxidant or heat stabilisers, and sometimes limit their effectiveness in stabilising the polymer chains,” he adds. Cabot says its Vulcan XTP50 specialty carbon black is well suited for use in applications requiring LTHS as it presents a favourable combination of UV protection and minimal interaction with the antioxidants and anti-UV agents used in engineer- ing thermoplastics. The company’s Plasblak XP6559A black master-
batch, the next generation version of Plasblak PA3785 masterbatch, enables compounders to boost the performance of PA compounds. It is suited for applications in the automotive sector that require high mechanical strength.
