What are the plastic finish types?
Plastic finishes are used by fabricators to give the product its final look and to reduce the appearance of any blemishes or molding lines. These finishes are separated into grades classified by the Society of Plastics Industry, or SPI. The SPI states that plastic finishes are spread out across twelve separate grades, ranging from mirror shine to a dull matte. In general, these finishes can be placed in four broad groups.
