Features: In recent years, the chemical industry standardization cause has been developing continuously, and great changes have taken place in chemical industry standards. To meet the needs of a broad readership for the standard texts of rubber raw materials, we have compiled and published the 2006 edition of the Rubber Raw Materials Standards Collection. This collection is divided into three volumes: Upper, Middle, and Lower. It gathers the current national standards and industry standards approved and published before the end of 2005. This volume, the Lower, is divided into five parts: Pigments, Foaming Agents, Adhesives, Skeleton Materials, and Other Standards. It collects a total of 130 standards, including 77 national standards and 53 industry standards. The attributes of the national standards collected in this collection are indicated in this catalog (GB or GB/T), and the year designator is expressed in four digits. Some national standards were published before the national standard cleanup and reorganization and have not been revised. Therefore, the original text is retained in the main body of these standards. When using these standards, their attributes should be referred to as indicated in this catalog (please note that readers should check the attributes of standards cited in the "References" section of the standard text). In the catalog of this collection, industry standards whose names are enclosed in parentheses with the original national standard number are derived from the transformation of national standards. As these standards have not been separately published as industry standard texts (i.e., only the industry standard number is provided, and the text content remains unchanged), the main body of this collection still retains the national standard text. Similar cases of professional standards being transformed into industry standards are handled in the same way. The standards included in this collection, due to differences in publication dates, may vary in format, units of measurement, and technical terms. This collection has only corrected errors in the technical content of the original standards and other obvious inappropriate places.
