研究表明，增加交联剂的含量会增加交联程度，从而增加TPV的粘度，但会伴随着加工性降低。一方面，随着交联程度的增加，橡胶颗粒的刚性增加，形变能力降低，导致TPV中橡胶网络的不稳定。另一方面，交联剂含量的增加导致TPV中较小的橡胶颗粒形成，从而导致TPV的粘度增加。交联剂类型的影响。Nakason等研究了不同交联体系对TPV流变性的影响。结果表明，在给定的剪切速率下，由于硫和过氧化物均产生NR相的交联反应，并且过氧化物在HDPE相中也产生了一定程度的交联反应，导致硫和过氧化物的混合交联体系交联的NR/HDPE-TPV中达到高剪切应力

The results show that increasing the content of crosslinkingagent will increase the degree of crosslinking and increase theviscosity of TPV, but it will be accompanied by the decrease ofprocessability. On the one hand, with the increase of crosslinkingdegree, the rigidity of rubber particles increases and thedeformation ability decreases, resulting in the instability ofrubber network in TPV. On the other hand, the increase ofcrosslinking agent content leads to the formation of smaller rubberparticles in TPV, which leads to the increase of viscosity of TPV.Effect of crosslinking agent type. Nakason et al. Studied theeffects of different crosslinking systems on the fluidity of TPV.The results show that at a given shear rate, the cross-linkingreaction of NR phase is produced by both sulfur and peroxide, andperoxide also produces a certain degree of cross-linking reactionin HDPE phase, resulting in the highest shear stress in NR /hdpe-tpv crosslinked by the mixed cross-linking system of sulfurand peroxide
