Grill plastics components

A few functional, exterior automotive plastic components, such as cowl-vent grills and windshield-wiper assembhes, are universally accepted as unpainted molded-in-color components. These are not typically overcoated. 

Although few automobiles contain exterior body panels made of plastics, a number of components are plastic. Examples include bumpers, trim, light lenses, grilles, dashboards, seat covers, and steering wheels—enough plastics to account for an average of 250 lb per car. The increased emphasis on... 

In recent years, plastics have been used to replace some metal products. They have lighter weight, low corrosion, and are electrically non-conductive. Plastics are easy to color and offer design flexibility. Metal components have been replaced by amorphous plastics like polyvinyl chloride and by crystalline plastics such as polypropylene and polyethylene [12]. Processes for plating on plastics to give a bright metallic surface (example automobile grill) have been developed too. 

Grille opening reinforcements - GE Plastics NORYL PPX resins are a popular choice for this application, which requires materials that are tough and dimensionally stable for component system performance, and also moisture, heat and vibration resistant.
