Plastic's usage and importance is growing. What special hardness testing considerations does it have? Material quality is often synonymous with how well a material meets its performance expectations.
Plastic materials that are frequently tested for hardness include plastic sheeting and molded parts. Products such as rigid thermo-plastics, Plexiglas, thermo-polystyrene, vinyl sheeting, cellulose acetate, and thermosetting laminates such as Formica are commonly tested for hardness too.
