21、is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be repres
22、ented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are
23、drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International
24、 Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

25、red by Technical Committee ISO/TC 45, Rubber and rubber products. EN ISO 18064:2005vIntroduction Thermoplastic elastomers combine many of the attributes and features of both vulcanized thermoset rubber and thermoplastic materials. It is, therefore, important that any system of classification and nom
26、enclature for this rapidly expanding polymer sector should be acceptable to both the rubber and plastics industries. Neither of the existing standards for the nomenclature and abbreviated terms for rubber (ISO 1629) and for plastics (ISO 1043-1) is suitable for this purpose. The system in this Inter
27、national Standard has been devised to avoid any conflict of interests or ambiguity, permit the use of existing terms in the construction of abbreviations for thermoplastic elastomers, and allow for future developments or expansion. This International Standard uses established abbreviated terms. Its
28、aim is both to prevent the occurrence of more than one abbreviated term for a given thermoplastic elastomer term, and to prevent the interpretation of more than one meaning for a given abbreviated term. For this reason, this International Standard makes appropriate use of the terms and symbols liste
29、d in ISO 1043-1 and ISO 1629. EN ISO 18064:2005blank1Thermoplastic elastomers Nomenclature and abbreviated terms 1 Scope This International Standard establishes a nomenclature system for thermoplastic elastomers based on the chemical composition of the polymer or polymers involved. It defines symbol
30、s and abbreviated terms used to identify thermoplastic elastomers in industry, commerce and government. It is not intended to conflict with, but to supplement, existing trade names and trademarks. NOTE 1 The name of the thermoplastic elastomer should be used in technical papers and presentations fol
31、lowed by the abbreviated term used to designate the elastomer in this International Standard. NOTE 2 Annex A gives thermoplastic-elastomer abbreviated terms that have been used in the past in materials standards, technical bulletins, textbooks, patents and trade literature. 2 Normative references Th

38、having little or no crosslinking. 5.4 TPS Styrenic thermoplastic elastomer, consisting of at least a triblock copolymer of styrene and a specific diene, where the two end blocks (hard blocks) are polystyrene and the internal block (soft block or blocks) is a polydiene or hydrogenated polydiene. 5.5
39、TPU Urethane thermoplastic elastomer, consisting of a block copolymer of alternating hard and soft segments with urethane chemical linkages in the hard blocks and ether, ester or carbonate linkages or mixtures of them in the soft blocks. 5.6 TPV Thermoplastic rubber vulcanizate consisting of a blend
40、 of a thermoplastic material and a conventional rubber in which the rubber has been crosslinked by the process of dynamic vulcanization during the blending and mixing step. 5.7 TPZ Unclassified thermoplastic elastomer comprising any composition or structure other than those grouped in TPA, TPC, TPO,
41、 TPS, TPU and TPV. EN ISO 18064:200536 Materials in each TPE category 6.1 Polyamide TPEs (TPAs) The “TPA” group is sub-categorized into groups according to the linkages in the soft blocks.

43、.3 Olefinic TPEs (TPOs) The “TPO” group varies according to the nature of the thermoplastic polyolefin being used and the rubber type. A specific TPO is identified by a bracketed term comprising the standard abbreviation for the rubber type (see ISO 1629), a “+” sign and the standard abbreviation fo
44、r the thermoplastic type (see ISO 1043-1). The thermoplastic and the rubber type shall be listed in decreasing order of abundance in the TPO. A commercially available TPO type is described as follows: TPO-(EPDM+PP) Blend of ethylene-propylene-diene terpolymer with polypropylene, with no or little cr

47、 in which the polyisoprene block has been hydrogenated. EN ISO 18064:20054 6.5 Urethane TPEs (TPUs) The “TPU” group is sub-categorized into types according to the nature of the hydrocarbon moiety (aromatic or aliphatic) between the urethane linkages of the hard blocks, and according to the chemical
