Super small pellets for colour homogeneity Delta Tecnic, an expert in masterbatch manufacturing for the plastics industry, is launching a new product: the Super Small Pellet. The solution represents advancement in masterbatch technology by offering improvements in colour homogenisation and efficiency in transformation processes.

reducing the need for workers to wear masks during grinding processes. The versatility of SSP in particle size allows production from small batches of 25kg to large volumes as needed. This flexibility is advantageous in manufacturing PVC films, compounds and rigid profiles, where achieving optimal dilution is critical. The ability to produce small batches supports customisation of colours and properties, enabling Delta Tecnic customers to meet specific application needs. The SSP production process also has a lower carbon footprint than traditional methods, because it eliminates the need for mills and other energy-intensive equipment. This approach not only enhances efficiency but also promotes sustainability by reducing resource consumption and waste generation. By minimising energy requirements and waste production, SSP represents a more eco-friendly option for plastic manufacturers. Delta Tecnic SA www.deltatecnic.com

Super Small Pellets

In masterbatch manufacturing, the market has traditionally used standard sized granules, which have certain limitations in colour dilution and homo- genisation in final products for specific applications. Delta Tecnic has developed different pellet sizes, ranging from micropellets to small micropellets (SMP). The new Super Small Pellet (SSP) is an even smaller design to optimise dilution. With a smaller diameter, the Super Small Pellet integrates more efficiently, cover- ing the same colour surface area with a greater number of small particles rather than fewer larger ones. This enhances the quality of the final product, ensuring visual uniformity without irregularities. In the PVC industry, where raw materials are often in powder form, the use of

large pellets can lead to settling issues, where heavier grains settle at the bottom of the mix. The SSP offers a more uniform size, minimising such problems. Reducing pellet size also facilitates better integration into the mix, preventing segregation issues and ensuring a homogeneous distribution of colour and additives. The SSP is manufactured using an advanced process distinct from traditional cryopellet production, which typically involves cryogenic grinding. This new manufacturing method reduces the generation of fine particles, which enhances product quality and improves worker safety. Smaller particles are less likely to be inhaled during handling,
