《GB/T 15257-2008混合调节型氯丁二烯橡胶 CR321、CR322》由TC35(全国橡胶与橡胶制品标准化技术委员会)归口,TC35SC6(全国橡胶与橡胶制品标准化技术委员会合成橡胶分会)执行,主管部门为中国石油和化学工业联合会。
本标准规定了混合调节型氯丁二烯橡胶CR321 系列中CR3211、CR3212、CR3213 和CR322 系列中CR3221、CR3222、CR3223的技术要求、检验方法、检验规则以及包装、标志、储存、运输。
本标准适用于以氯丁二烯为单体,硫磺和调节剂丁为调节剂,经乳液聚合制得的CR3211、CR3212、CR3213、CR3221、CR3222、CR3223。


This standard specifies technical requirements, inspection methods, inspection rules and packing, marking, storage and transportation of CR3221, CR3222 and CR3223 of series CR3211, CR3212, CR3213 and CR322 in mixed modulation chloroprene rubber CR 321 series.
This standard is applicable to CR3211, CR3212, CR3213, CR3221, CR3222 and CR3223 made by polymerizing emulsion, with chloroprene as monomer and sulfur and dithiodiisopropyl xanthate as the moderator.
