氢是自然界存在最普遍的元素，其燃烧产物是水，没有含碳化合物等污染物，是世界上最干净的能源。作为二次能源，可由众多可再生的一次能源转化而成，并且资源丰富，可循环利用。随着科技发展，氢能逐渐成为全世界关注的重点，势必成为清洁能源的新宠儿。

Hydrogen has excellent combustibility and is an efficient clean energy source, but this characteristic has also become a double-edged sword. This makes hydrogen highly susceptible to combustion and explosion when in contact with air. Based on safety considerations, hydrogen has strict requirements for equipment sealing during production, storage, and transportation.

氢气的燃烧性极好，是一种高效的清洁能源，然而这种特性也成为了一把双刃剑。这使得氢气与空气接触时极易发生燃烧和爆炸，基于安全性的考虑，氢气在生产、存储、运输的过程中对设备的密封有着严苛的要求。

As the element with the smallest formula quantity, the sealing difficulty of hydrogen is evident. SealTex gaskets have successively passed hydrogen leakage testing, providing various solutions for sealing problems in hydrogen energy production, storage, transportation, and other processes:
