Compounding. The art of mixing, reinforcing and incorporating additives to plastics.
Plastics are probably the most versatile materials that human being has developed.
In order to achieve these good properties, a correct mixing process is essential and this will depend on a current screw design, appropriate control process, the good selection of peripherals and the experience to solve the problems that appear during the compounds production.
