Novablend System

Colortronic Inc.'s new Novablend System, using automated Colortronic gravimetric feed components and a Waeschle mixing turbine, now makes it possible to accomplish PVC compounding as a continuous process.

Affordable scaleable production for precision blends as well as flexible formulations with higher accuracy and lower overall costs, the Novablend system eliminates the need for the high energy consumption and large building/infrastructure requirements associated with conventional PVC mixing plants. In addition, it simplifies material handling, saves resin on color changes, and let processors add capacity easily.

This dramatically changes the way in which PVC compound can be made, creating a new paradigm for production that has economy and efficiency at its core; one that is well suited to many different product compositions.

The use of Novablend System results in less raw material consumption and reduced scrap, higher outputs, reduced errors, minimized environmental impact and a consistently higher-quality end product. Its outstanding features also include no cooling steps required, dust-free production, a minimum space requirement, absolute continuous online compounding and processing, short changeover and cleaning times, and simple operation.

The Novablend System brings real capital efficiency to PVC blending. In addition to savings on material and logistics, Novablend adds new profit to the entire process by allowing for enhanced product formulations while improving the bottom-line cost per pound or kilogram of output.

The Novablend process mixes raw PVC resin, calcium carbonate fillers, liquid stabilizers and colorants with high intensity, but without heat. Unlike conventional systems, Novablend creates sufficient nominal friction to raise the temperature of PVC powder enough to absorb the liquid stabilizers for rigid PVC.

The system consist of a Colortronic gravimetric blender and liquid doser, a specially-designed horizontal mixing screw also developed by Colortronic, and a high-speed mixing turbine developed by Waeschle S.r.L., Italy. Energy use is approximately one-tenth of the amount required for conventional systems.
