In recent years, microbubble technology has attracted great attention in many application fields including water treatment, food processing, oil recovery, surface cleaning, and therapeutic applications. In this paper, microbubbles (MBs) of air, nitrogen, and argon were applied to produce natural rubber latex foams (NRLFs). The bubbles were generated by flowing the gas through a porous diffuser and latex. The effect of gas source on cellular structure, density, elasticity, indentation hardness, and flammability of the bubbled foams was discussed. Argon MBs offered the latex foams with fine cell diameters and uniform cell size distribution resulting in enhanced elasticity and physical properties of the foams. Indentation hardness index and limiting oxygen index value depended significantly on the gas used. By using the microbubble technique, the future prospects in NRLF production can be expected due to its ability in controllable cellular structure.

近年来，微气泡技术在包括水处理、食品加工、石油回收、表面清洁和治疗应用在内的许多应用领域引起了极大的关注。在本文中，空气、氮气和氩气的微气泡 (MBs) 被用于生产天然橡胶乳胶泡沫 (NRLFs)。气泡是通过使气体流过多孔扩散器和乳胶而产生的。讨论了气源对发泡泡沫的孔结构、密度、弹性、压痕硬度和可燃性的影响。Argon MB 为乳胶泡沫提供了细小的泡孔直径和均匀的泡孔尺寸分布，从而增强了泡沫的弹性和物理性能。压痕硬度指数和极限氧指数值在很大程度上取决于所使用的气体。通过使用微泡技术，
