The effect of petroleum resins (PRs) and asphaltene–resin substances (ARSs) on the technological and physicomechanical properties of noncurable butyl rubber sealants has been studied. It has been shown that sealants containing PRs have higher water resistance and greater durability than do sealants with bitumens as technological additives.

石油树脂和沥青质-树脂物质对丁基橡胶密封胶性能的影响

已经研究了石油树脂 (PRs) 和沥青质树脂物质 (ARSs) 对不可固化丁基橡胶密封胶的技术和物理机械性能的影响。已经表明，含有 PR 的密封剂比使用沥青作为技术添加剂的密封剂具有更高的耐水性和更好的耐久性。
