Figure 9.1 shows a classification of plastics with regard to their bondability. 

Classification of Plastics, Elastomers, and Rubber (NFPA 231C) NOTE The following categories are based on unmodified plastic materials. The use of fire or flame-retarding modifiers or the physical form of the material may change the classification. 

In the broad classification of plastics there are two generally accepted categories thermoplastic resins and thermosetting resins.

Abstract This chapter defines Environmentally Friendly Polymer Engineering as the basic organizational system of the first volume of these two books. The classification of plastics, and a list of their main characteristics, follows. This chapter closes with some economic data. 

Adequate classification of plasticizers is diffienlt because of their diversity. The following, traditional classification is generally aeeepted [98, 360] ... 

Some of the test methods of flame spread rate are devoted to the classification of plastics into various flammability groups.
