Uses of natural rubber are numerous and well known (tires, pipes, shoes, ). In some cases, synthetic rubbers are prefered due to their specific properties and their lower cost importance. Thermogravimetry allows to compare their resistance to temperature. The investigation is run on the following elastomers : natural rubber, butyl rubber, cis-polybutadien, polychloropren (Neoprene). 高溫動態(tài)彈性模量和阻尼分析系統(tǒng) 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 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)
