试验证明了氟硅橡胶是唯一能可靠密封兰斯(Lance)导弹氧化剂活塞的材料。活塞借热气的驱动将红色发烟硝酸送入导弹的反应发动机。密封件是武器的最苛刻部件之一,因任何泄漏都可能导致导弹的爆炸。兰斯导弹是由 LTV 宇航公司制造的,它是第一种陆军战地炮兵导弹,使用预包装的可贮存液体推进剂。两种燃料——偏二甲肼(UDMH)和硝酸氧化剂分别贮存于直径为 Tests have shown that fluorosilicone rubber is the only material that reliably seals Lance missile oxidizer pistons. Pistons driven by hot red fuming nitric acid into the reaction of the missile engine. Seals are one of the most demanding parts of a weapon, as any leak can cause the missile to explode. The Lance missile, manufactured by LTV Aerospace, was the first Army Battlefield artillery missile to use pre-packaged storable liquid propellants. Two fuels - UDMH (UDMH) and nitric acid oxidizer were stored in diameter
