This standard establishes a system of symbols for basic rubber in both dry and latex forms. The symbol system is based on the chemical composition of the polymer chain. The purpose of this standard is to standardize the terminology used by industry, commerce and regulatory agencies. This system is not intended to contradict existing trade names and trademarks, but rather to supplement them.

GB/T5576—1997
This standard is equivalent to ISO1629:1995 "Rubber and latex - Nomenclature" to revise GB/T5576—85 "Synthetic rubber nomenclature". The technical content and writing format are completely consistent with the adopted standard. Compared with the previous version, the variety sequence and symbol code of this standard have been adjusted. The rubber varieties have been supplemented and modified. Appendix A of this standard is a prompt appendix.
This standard is proposed by China Petrochemical Corporation. This standard is under the jurisdiction of the Synthetic Rubber Sub-Technical Committee of the National Technical Committee for Standardization of Rubber and Rubber Products. Drafting unit of this standard: Chemical Research Institute of Lanzhou Chemical Industry Corporation. The main drafters of this standard: Guo Hongda and Chen Shufen. This standard was first issued in October 1985. The Chemical Research Institute of Lanzhou Chemical Industry Corporation is responsible for the interpretation of this standard. 14

ISOForeword
ISO (International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of developing international standards is usually carried out by ISO technical committees. Any member body interested in the subject of an established technical committee has the right to participate in that committee. International organizations, both governmental and non-governmental, in contact with ISO may also participate in this work. ISO works closely with the International Electrotechnical Commission (IEC) on all aspects of electrotechnical standardization. Draft international standards adopted by technical committees are circulated to member bodies for voting. When published as international standards, at least 75% of the voting member bodies are required to vote in favor.
International Standard ISO1629 was developed by ISO/TC45 Technical Committee Rubber and Rubber Products. This third edition abolishes and replaces the second edition (ISO1629:1987) and is a technically revised version of the second edition. Appendix A of this international standard is for reference only.

1.1 This standard establishes a system of symbols for basic rubbers in the form of dry rubber and latex. The symbol system is based on the chemical composition of the polymer chain.
1.2 The purpose of this standard is to standardize the terms used by industry, commerce and regulatory agencies. This system is not intended to conflict with existing trade names and trademarks, but rather to supplement them. Note 1: In technical documents or literature, the rubber name should be used as much as possible. These symbols should be placed after the chemical name for later reference. 2 Rubber
Rubbers in both dry and latex forms are grouped and represented by symbols based on the chemical composition of the polymer chain as follows: M Rubbers with polymethylene type saturated carbon chains N Rubbers containing carbon and nitrogen in the polymer chain
Note 2: There are no rubbers represented by the N group of symbols. 0
Rubbers containing carbon and oxygen in the polymer chain
Rubbers containing silicon and oxygen in the polymer chain
Rubbers with unsaturated carbon chains. For example: natural rubber and synthetic rubber made at least partly from conjugated dienes R
Rubber containing carbon, oxygen and sulfur in the polymer chain U
Rubber containing carbon, oxygen and nitrogen in the polymer chain ZRubber containing phosphorus and nitrogen in the polymer chain

Note 3: In ISO1043-1E1}, the symbol for siloxane compounds is SI. 3.4 “R\ Group
3.4.1 Explanation
The “R” group, which includes both dry rubber and latex, stipulates that the word “rubber” is preceded by the name of one or more monomers (except natural rubber) used to prepare the rubber. The letter before the letter “R\” indicates the conjugated diene used to prepare the rubber (except natural rubber). The one or more letters before the diene letter indicate one or more comonomers, substituents or chemical compositions. The letter E and a hyphen “_” are placed before the name to indicate an emulsion-polymerized rubber, and the letter S and a hyphen “_” are placed before the name to indicate a solution-polymerized rubber. For latex, the word “latex” is added after the specific symbol. For example, “SBR latex”. Use the symbols listed in 3.4.2 to 3.4.4. 3.4.2 Ordinary rubber
