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. 醫(yī)學(xué)生物高靈敏度差示掃描量熱儀 新型固體微量水份測試儀 導(dǎo)熱儀 高溫動態(tài)彈性模量和阻尼分析系統(tǒng) 自動調(diào)節(jié)臨界氧指數(shù)儀 熱變形／維卡軟化點測試儀 同步熱分析儀(綜合熱分析儀)
