Super small pellets for colour homogeneity Delta Tecnic, an expert in masterbatch manufacturing for the plastics

The portfolio includes all necessary equipment, from payoff units, straight ening and indenting units, heating and pulling units to the final take-up for coils and bars. This process, largely due to thermo- mechanical treatment, relieves drawing stresses, enhances yield strength and reduces relaxation losses, ensuring a consistent modulus of elasticity. MFL’s thermomechanical treatment section offers precise temperature and tension control, leveraging the latest technology and extensive field experience. For bar production, the machinery fea tures cutting heads capable of handling maximum line speeds of 150m/min and collecting bars of various lengths. As part of its turnkey solution, MFL offers plant engineering, final layout design, process flow optimisation, and local support through service departments in Italy, the USA and China. particles are less likely to be inhaled during handling, 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

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. In masterbatch manufacturing, the market has traditionally used standard sized granules, which have certain limitations in colour dilution and homogenisation 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, covering 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

and electrolytic phosphating. The aim of mechanical rod preparation combined with electrolytic phosphating is to minimise waste disposal (especially acids) while ensuring consistent rod cleaning. In the drawing phase, MFL provides drawing lines that ensure final product quality through advanced cooling efficiency, design reliability and reduced energy consumption. 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

The production lines are entirely internally designed, featuring multiple patents (eg cooling system) and utilising proprietary gearbox designs. Following the wire drawing phase, the product undergoes thermomechanical treatment to achieve the required characteristics. MFL Group offers LRPC wire lines designed to meet these requirements.
