天然橡膠,天然橡膠彈性體性質(zhì)的主要“現(xiàn)成的"貢獻(xiàn)。高彈性,表現(xiàn)只有一些zui近的人造聚異戊二烯和聚丁二烯。這展覽很好的拉伸和撕裂性能在剛度范圍寬,具有良好的抗冷流。耐磨性好。天然橡膠具有較好的低溫靈活性比大多數(shù)的人工合成物,但不如硅橡膠。天然橡膠不年齡以及許多人工合成物也不像一些惰性。它不如許多人工合成材料的熱老化、耐陽(yáng)光、氧氣、臭氧、溶劑或油。通用橡膠主要用于水性液體填充產(chǎn)品pH值在4.0 - 4.0范圍內(nèi)。天然橡膠的彈性的橡膠類型。它有很好的耐磨損和疲勞。缺點(diǎn)是材料的窮人中抗臭氧(天氣)和油和燃料。
Natural Rubber - Natural rubber is nature's main "ready-made" contribution to the elastomer field. It has high resilience, outperformed only by some of the more recent man-made polyisoprenes and polybutadienes. It exhibits very good tensile and tear properties over a wide stiffness range and has excellent resistance to cold flow. Abrasion resistance is good. Natural rubber has better low-temperature flexibility than most synthetics, but is not as good as silicone rubber. Natural rubber does not age as well as many of the synthetics nor is it as chemically inert as some. It is inferior to many of the synthetics for heat aging, resistance to sunlight, oxygen, ozone, solvents or oils. A general purpose elastomer intended primarily for aqueous liquid fill products in the 4.0 - 7.5 pH range. Natural rubber has the best elasticity of all rubber types. It has very good resistance to abrasion and fatigue. Among the drawbacks are the material’s poor resistance to ozone (weather) and oils and fuels.
