The order of compression permanent deformation of various raw rubber:

In general, the elastic rubber with high elasticity and high strength is self-reinforcing, and its deformation is easy to recover, and the compression set is small; while the structure has many side chains, many branches, and many genes, The resistance is large, it is not easy to recover after deformation, and the residual deformation is large. For example, BR, NR, CR, FKM have smaller compression set, while TR, IIR, and SBR have larger compression set. Because SBR has the largest hysteresis loss, its compression set is large.
Followed by the rate of gelatin. If the rubber content is high (60% or more) and the filler is small, the voids in the spatial network structure of the crosslinked bonds of the vulcanized rubber after vulcanization are large, and are easily collapsed after being stressed, and the compression permanent deformation is large. The rubber content is low (30% or less), the filler is many, and the void of the space network structure of the vulcanized rubber after vulcanization is small. After being stressed, the stiffness is large and it is not easy to be deformed, so the compression deformation is small. If the rubber content is medium, the compression set is centered, between the two.

The following are the hardness, degree of vulcanization, type of crosslinks, carbon black, shape of filler particles, and the like.
Rubber hardness:
The hardness of the compound depends on the amount of vulcanizing agent, reinforcing agent and filler. Generally speaking, if the amount is high, the hardness of the vulcanized rubber is high, the compression set is small, and the product is suitable for the high hardness product; while the amount of the vulcanized rubber is low, the compression set is large, and the compression set is large, suitable for For low hardness products. It should be noted that a rubber product having a high hardness has a small shrinkage ratio and a rubber product having a low hardness, and has a large shrinkage ratio. The high-hardness rubber products above 85° have an increase in shrinkage. Therefore, it should be considered when designing the formula.
When the amount of reinforcing agent or filler (hardening) is medium (moderate), the compression set is centered.
