The product is LSR O seal, which has better airtightness than elastomer and the other characters of high temperature resistant, anti-aging, anticorrosive, non-toxic and environmental protection.

现场所生产的产品是汽车用液态硅橡胶密封圈，它比热塑性弹性体具有更好的密封性、耐高温、耐老化、耐腐蚀和无毒环保等特点。

The present study shows that there is a critical seal pressure which is only related to the compression ratio and the friction coefficient, but does not depend on the radius of the elastomer ring.

分析结果表明，临界密封压力只与橡胶圈的压缩量和密封面摩擦系数有关，与橡胶圈截面半径无关。
