Delta Tecnic can help compounders with masterbatches

Delta Tecnic also claims to provide an advantage in colour uniformity, with dilution and dispersion to ensure the pigments have the same colour in each production. The company can also supply a masterbatch formulated with the mixture of additives so that compounders can add it to their process with the use of a single raw material, saving mixing work and enabling the precise control of percentages and homogeneity in the final product. In the cable industry, the use of halogen free and flame-retardant (HFFR) compounds is common. The formulations of this type of compound are complex and require numerous raw materials. For this specific market, Delta Tecnic offers custom-made masterbatches with the required combination of additives, simplifying both the formula and production, and ensuring homogeneity of the additives in the final product.

dispersion of the materials, accelerating and optimising the processes of com- pound manufacturers. Cleanliness is one value that amasterbatch manufacturer such as Delta Tecnic can bring to a compound manufacturer. Pigments are dirtier than masterbatches – especially carbon black. Delta Tecnic is helping to eliminate this type of powder from compounders’ processes and replacing it with masterbatch, a cleaner solution that generates time savings: the cleaning time of the turbo mixer is reduced by a claimed 80 per cent when using masterbatch instead of pigments. When a compound manufacturer defines a colour for weathering, it must select pigments to achieve adequate light and weather fastness. Delta Tecnic can help resolve colours in this type of application, using its knowledge of the behaviour of pigments in outdoor PVC, and having tested many pigments in ageing chambers, providing definition for colours that are hard to resolve.

PVC masterbatch specialist Delta Tecnic has established itself as a supplier for compounders through its historical knowledge and innovative machinery. The raw materials of the compounding industry are supplied to strategic sectors such as cable, automotive and construction. This gives the industry a fundamental role in future sustainability. Continual regulatory review is pushing the sector to adapt to market demands. The plastics compounding market reached a global value of $61.4bn in 2020, and is expected to grow at a compound annual growth rate of 5.5 per cent through to 2028, according to a report by Grand View Research. The forecast indicates that the increasing substitution of glass, metals, wood, natural rubber and artificial materials, such as concrete, will drive this growth. In this aspect, Delta Tecnic has the tools to work with the pigment powder and special additives to obtain an even
