II- NONMETALS Plastic materials Ceramic materials PLASTICS AS MATERIALS OF CONSTRUCTION FOR CHEMICAL PLANTS They can be divided into two broad classes: 1. Thermoplastic materials, which soften with increasing temperature; for example, polyvinyl chloride (PVC) and polyethylene. 2. Thermosetting materials, which have a rigid, cross-linked structure; for example, the polyester and epoxy resins. II- NONMETALS Plastic materials Ceramic materials
