Designation of Inhibited Plastics

To conclude Chap. 1, we would like to present a classification of inhibited plastics by their properties and application fields (Fig. 1.20). One can find detailed description of different types of inhibited plastics further in this book in corresponding chapters. 

An inhibited polymer coating represents a layer of a polymer-based composite material bonded with the substrate via an adhesive layer. The composite material may contain a plasticizer, corrosion inhibitor and technological additives in its composition (see Chap. 3). The coatings are subdivided into peelable and unpeelable by their behavior and the intensity of their adhesive interactions with the article being protected. 

The coatings can be melt-laid, applied in suspensions based on polyolefines or their halogen-derivatives, polyesters, acrylates, epoxy resins, cellulose derivatives and numerous copolymers. 

Unpeelable inhibited coatings are used largely as primers preceding the paintwork on cars and equipment. 

Parts of friction joints and seals are often made from inhibited structural plastics (see Chap. 4). Their main role in metal-polymer friction joints is to abate Mechano-chemical wearing of metal counterbodies. Application of inhibited antifrictional materials is considered to be a promising trend for extending the life of friction joints operating in hostile media. The structural polymers or their blends most often contain plasticizers. Cl, fillers and modifiers as additional components. The inhibited plastics are employed in plain bearings, sealing elements and other members of oil-extracting equipment and vehicles.
