  "definition": "Foamed plastics (or foams) have a unique cellular structure that is different from solid plastics.For this reason, foams are often called “cellular plastics.” Foams, which are rigid, semi-rigid, or flexible, can be manufactured with thermoplastic or thermoset resins. Many of the manufacturing techniques used to fabricate solid plastic products are also used to make foam products. The process used to manufacture foams influences the properties of the final foam product.",
