4.44万t,其他助剂1万t,均比上年有不同幅度增长。随着一批新装置陆续建成并投产,防老剂RD和不溶性硫黄产能迅速扩大,产量大幅增长,是助剂产品中产量增长较快的品种。相对而言,促进剂主流品种如促进剂NS和CZ等产量增长平稳,值得一提的是在总量增长的情况下,促进剂NOBS和TMTD的产 44,400 tons, 10,000 tons of other auxiliaries, all with different growth rates over the previous year. With a number of new installations being built and put into operation one after another, the RD capacity and insoluble sulfur capacity have rapidly expanded and the output has risen sharply. Relatively speaking, the mainstream varieties of accelerators, such as NS and CZ, have shown steady growth. It is worth mentioning that in the case of aggregate growth, the production of NOBS and TMTD
