‘Super’ Small Color Masterbatch Pellets for PVC

What are said to be ‘super’ small color and additive masterbatch pellets for polyvinyl chloride (PVC) have been developed by Spain’s Delta Tecnic (U.S. office - Boston, Massachusetts, and product supplied through the company’s Querétaro, México, manufacturing facility). The newly launched Super Small Pellet (SSP) masterbatches are said to boast substantial improvements in color homogenization and efficiency in transformation processes.

Traditionally, the market has used standard granules, which, while functional, have certain limitations in color dilution and homogenization in final products for specific applications. Over time, Delta Tecnic has developed different pellet sizes, ranging from micropellets to small micropellets (SMP).

The company has now taken a further step forward with the SSP — an even smaller pellet designed to optimize dilution. Due to its smaller diameter, the SSP integrates more efficiently, covering the same color surface area with a greater number of small particles rather than fewer larger ones. This is said to significantly enhance the quality of the final product, ensuring visual uniformity without irregularities.

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 by minimizing the risk of inhaling fine particles.

Smaller particles are less likely to be inhaled during handling, reducing the need for workers to wear masks during grinding processes. The SSP’s versatility in particle size enables production from small batches of 25 kg to large volumes as needed. This flexibility is particularly advantageous in manufacturing PVC films, compounds and rigid profiles, where achieving optimal dilution is critical.

Moreover, the ability to produce small batches supports customization of colors and properties, enabling Delta Tecnic’s customers to swiftly meet market demands and specific application needs. Because it eliminates the need for mills and other energy-intensive equipment, this approach also promotes sustainability by reducing resource consumption and waste generation.
