Color Concentrates for Recycled PVC

A line of colorants specifically designed to help enhance the color of recycled PVC products, whether in black, white, or any other specific color has been introduced by Spain’s Delta Tecnic (U.S. office in Boston, Mass., and product supplied through company’s Querétaro México manufacturing facility). This line of color masterbatches are based on new formulation technology designed to meet the market needs for sustainability. The company offer three different approaches to coloring recycled PVC:

 ▪  PVC that is made up of different colors is usually transformed into black using carbon black concentrates.·

 ▪  For white PVC, which is to be reintroduced in the same color, it is important to note that due to thermal stress, the recycled product tends to yellow. For this reason, Delta Tecnic offers a range of white masterbatches containing titanium dioxide (TiO2), in many cases custom made, that help improve the final color

 ▪  For manufacturer that want to make parts in a specific color, Delta Tecnic recommends separating the residual products by color and making a specific masterbatch for each color, thus improving the final color of each part.

The company has been helping the PVC industry to incorporate color in all its applications for more than 40 years. Delta Tecnic also now supplies its special masterbatches to be introduced during the PVC recycling process to improve the quality of the final component. The latest market study by the consulting firm Ceresana on PVC, now in its seventh edition, forecasts that the demand for PVC will continue to grow and reach some 127 billion lbs worldwide in 2031. In Europe, more than 1.8 billion lb/yr are already recycled; that is, more than a quarter of all PVC waste.
