Jiangsu Xinmin Being Optimistic on PBST Prospect Summary: Jiangsu Xinmin is actively accelerating R&D of PBST, according to CCM Internationalâ€™s April issue of Biomaterials China News. Tags: biomaterial, PBST, Jiangsu Xinmin, R&D, textile, PBS, PBT, PBS fiber Jiangsu Xinmin Textile Science & Technology Co., Ltd. (Jiangsu Xinmin), a listed textile company in Wujiang City, Jiangsu Province, is actively accelerating R&D of poly(butylene succinate-coterephthalate) (PBST), according to CCM Internationalâ€™s April issue of Biomaterials China News. Jiangsu Xinmin has been doing R&D of PBST since 2009. Meanwhile, Jiangsu Xinmin has got the financial subsidy of about USD870,000 to support its R&D of PBST from Wujiang City Government since 2010. In fact, Wujiang City has also provided other financial subsidy of about USD690,000 to Jiangsu Xinmin since 2009, in order to help Jiangsu Xinmin improve its innovative ability, according to 2009, 2010 and 2011 annual reports of Jiangsu Xinmin. The following factors may be the major reasons for Jiangsu Xinmin to invest in R&D of PBST. Currently, R&D of PBST is still in primary stage and PBST is produced by poly(butylene succinate) (PBS) and poly (butylene terephthalate) (PBT). Compared with PBS, a biodegradable material widely used in plastics and films, PBST has some obvious advantages in fiber field. Although PBS has good biodegradability, its application in fiber field is limited by its low molecular weight, low melting temperature and poor mechanical property. Meanwhile, although PBT's biodegradability is bad, PBT is widely used in textiles, nonwovens and engineering plastics, thanks to its good thermal and processing properties. Therefore, PBST not only has good biodegradability but overcome the disadvantages of PBS, which creates a bright prospect in fiber field for PBST. Meanwhile, PBST has better spinnability than that of PBS. Compared with PBS's poor performance, such as fragile PBS fiber and poor extension ability, PBST extension ability can reach 2 times and its strength is enough for further processing after spinning. Moreover, PBST also has a little better performance in resiliency and boiling water shrinkage. Furthermore, as a listed company, Jiangsu Xinmin can expand business scope and attract more attention of investors in stock market through developing new environmental-friendly fibers.
Moreover, as a new environmentally friendly material, PBST, just like PBS, will also get much more support from the Chinese government in the next several years, thanks to the "Twelfth FiveYear Plan for New Materials Industry" released by Chinese Ministry of Industry and Information Technology (MIIT) on February 22, 2012.
