17、n accordance with Terminologies D 883and D 1600.3.2 Definitions of Terms Specific to This Standard:3.2.1 sulfone plastics, nplastics based on any of variousaromatic polymers which contain diphenyl sulfone in thebackbone of the repeating unit of the molecule.3.2.1.1 DiscussionAll of the sulfone polym

18、ers which areunder this specification contain ether oxygen which is anecessary component of the polymers as in the diphenylsulfone moiety. Examples of moieties which can be part of thebackbone of the repeating unit, in addition to diphenyl sulfone,are diphenyl isopropylidene, and biphenyl. Blends of

19、 thesepolymers can exist as well as co- and ter-polymers. Commer-cial polymers that are members of this class of thermoplasticsinclude polysulfone (PSU), polyether sulfone (PESU), andpolyphenylsulfone (PPSU) (see Fig. 1).4. Classification4.1 Unreinforced sulfone plastics are classified into groupsin

20、 accordance with their composition. These groups are subdi-vided into classes and grades as shown in Table SP.NOTE 3An example of this designation system is given below. Thedesignation SP0213 indicates the following:SP = sulfone plastics as defined in Section 3,02 (Group) = polyether sulfone, as def

21、ined in Terminology D 1600,1 (Class) = high temperature, and3 (Grade) = requirements given in Table SP.4.1.1 To facilitate incorporation of future or special materi-als the “Other” category for group (00), class (0), and grade (0)is shown in Table SP. The basic properties of these materialscan be ob

22、tained from Table A as they apply.4.2 Reinforced, filled, and lubricated versions of sulfoneplastics that are in Table SP are classified in accordance withTables SP and A. Table SP is used to specify the group ofsulfone plastics and Table A is used to specify the propertyrequirements after the addit

25、classification system uses the percent ofreinforcements or additives, or both, in the callout of the modified basicmaterial. The types and percentages of reinforcements and additivesshould be shown on the suppliers technical data sheet unless they areproprietary in nature. If necessary, additional c

26、allout of these reinforce-ment and additives can be accomplished by use of the suffix part of thesystem (see Section 5).4.2.2 Specific requirements for reinforcement, filled, orlubricated sulfone plastics shall be shown by a six-characterdesignation. The designation will consist of the letter “A” an

28、or can be obtained.4.2.3 When the grade of the basic material is not known, oris not important, the “0” grade shall be used for the reinforcedmaterials in this system.NOTE 5An example of this classification for a reinforced sulfoneplastics material is given as follows. The designation SP0210G30A4346

29、0would have the following material requirements:SP0210 = poly(ether sulfone) from Table SP,G30 = glass reinforced at the 30 % nominal level,A = Table A property requirements,4 = tensile strength, 95 MPa min,3 = flexural modulus, 4.5 GPa min,4 = Izod impact, 50 J/m min,6 = deflection temperature, 200
