There are many types of rubber sheets. The materials produced by any kind of rubber sheets are multi-component system materials mixed with main materials and various complexing agents, and each component plays a certain role.

For example, the vulcanization system can make the linear rubber macromolecules chemically cross-linked to form a three-dimensional space network structure, so that the plastic viscoelastic rubber becomes highly elastic vulcanized; the reinforcing filler can ensure that the rubber material has the required mechanical properties and improve processing performance and reduce cost; softening plasticizer can make the rubber material have the necessary process performance, improve cold resistance, and also reduce cost; anti-aging agent can improve the aging resistance of vulcanized rubber, which can prevent various aging and prolong the life of the rubber sheet. service life. So have you heard of colored rubber sheets? The following ATO shop will introduce things in this regard.

The dyeing method is complicated to operate, the dyeing agent and the complexing agent are dispersed unevenly, the color is poor, the solvent recovery is difficult, and the environment is polluted.

It is to add colorants or carriers, then add rubber sheets, and mix them uniformly through a rubber mixer. The specific method is as follows: dry powder plywood coloring, plywood color paste coloring, plywood texture coloring, plywood base material refining glue coloring.
