Matting agents are another key functional additive that delivers aesthetic benefits for plastics manufacturers. These additives modify the molded part surface to create a matte or frosted look. With the addition of matting agents, the surface gloss can be reduced, resulting in a more light-diffusing plastic part. These functional additives can add richness to a part’s appearance, therefore making the product more marketable, and giving it a perception of higher value and quality.
Matting agents are used to help reduce the gloss in polymers such as acrylonitrile-butadiene-styrene (ABS), polycarbonate (PC), and PC/ABS alloy. Matting agents help ensure that plastics don’t reflect too much light. Among the wide range of end-use products is PET polyester sheet and bottles, polyolefin films, automotive interior parts, vinyl siding, and other products. Matting agents commonly diffuse light that could potentially create a glare.
Matting agents play a key role in material selection because they eliminate the need to make sometimes difficult and costly re-surfacing adjustments to the molding tool. A stipple finish can be incorporated into a tool to provide a bumpy, rough finish which enables light to bounce off. However, these tool modifications can be expensive and time-consuming.
Matting agents are typically incorporated into masterbatch formulations for later addition during extrusion or molding of the plastic part. Most matting agents are specified for a particular type of resin.
