Tek-Spheres from Teknor Apex provide manufacturers of automotive instrument panels, airbag covers, and interior trim with bright molded-in color and appealing tactile properties. According to the company, the vinyl microbeads are simpler to process and less energy-intensive than powder blends and plastisols. Measuring 0.004 in (0.1 mm) in diameter, the vinyl microbeads flow freely over the inside of hollow molds in processes such as slush molding and rotomolding. Teknor Apex manufactures microbeads by melt compounding PVC resin with color, plasticizer, and other additives, producing a completely homogeneous material that melts rapidly in contact with a heated mold. The melt compounding process for microbeads also ensures a more uniform dispersion of color and additives, makes possible a broader range of durometers, and provides greater scope for incorporating new ingredients, including solid plasticizers.
