活性助剂是用于自由基硫化弹性体,以促进交联反应并改善物理性能的一类化学品。这些助剂一般带有多个官能团,能够参与一系列自由基反应,最明显的优点包括可以进行接枝和自由基加成反应。通过提高交联密度可改善诸如拉伸强度、模量和压缩永久变形等物理性能。大量用于自由基硫化 Co-agents are a class of chemicals used in free radical vulcanized elastomers to promote cross-linking reactions and to improve physical properties. These auxiliaries generally have multiple functional groups that are capable of participating in a series of radical reactions. The most obvious advantages include grafting and radical addition reactions. Physical properties such as tensile strength, modulus and compression set can be improved by increasing crosslink density. Used extensively for free radical vulcanization
