正文
Synthesis and Characteristic of Polyurethane Modified Siliconepolyurethane modified silicone (PUMS);polydimethylsiloxane (PDMS);polypropyleneglycol (PPG);2,4-toluenediisocyanate (TDI);Polyurethane modified silicone (PUMS) was synthesized from various molecular weights of polydimethylsiloxane (PDMS 2000, PDMS 6000, PDMS 20000), polypropyleneglycol with molecular weight of 3000 g/mol (PPG 3000) and 2,4-toluenediisocyanate (TDI) under tin catalyst. Their structures were confirmed by the measurement of FT-IR and $^1H-NMR$, and the thermal properties were studied from DSC and TGA. Glass transition temperature of PUMS exhibited exothermic peak at $-63{\\sim}-69^{\\circ}C$, and residual weight was 19~35% at $800^{\\circ}C$.

信息更新:

美国总工厂生产的0.5KG原始包装的PDMS延期至2021年9月16日后才能交货,默认我们将发国内库存的进口分装产品(02085925-0.5KG);另受制于有机硅大幅涨价潮影响,2021年9月1日后将上调销售价格,另行通知。Dow Corning=道康宁=Dow SiL=陶氏,都是同一家公司。 2021.09.01更新

美国总工厂生产的0.5KG包装的PDMS恢复正常进口,合法正规,质量金标准,欢迎订购使用。并承诺从我司购买的皆为原厂包装,100%未开封,附带技术手册,非国产灌装仿制、非分装、非仿冒外包装产品,可以放心使用。大量订购更有优惠。2021.04.01更新

备注:由于dowsil与道康宁公司合并,美国总工厂生产的PDMS,价格涨幅高达1倍之多,因针对科研用户使用,特备货规格0.5KG。如果您需要美国总工厂原厂生产的大规格包装的预定,可以与QQ 11366508联系给予报价/货期。2021.05更新
