Isothermal stability of polybutadiene

Elastomers are often employed in severe conditions of use, particularly of temperature (joints, pipes, ). Optimal conditions of use must be well defined in order to know when to make replacement. Isothermal thermogravimetry gives information on the resistance of elastomer to a given temperature and determines its decomposition kinetics. The investigation is run on cis-polybutadiene. 医学生物高灵敏度差示扫描量热仪 新型固体微量水份测试仪 导热仪 高温动态弹性模量和阻尼分析系统 自动调节临界氧指数仪 热变形／维卡软化点测试仪 同步热分析仪(综合热分析仪)
