Unvulcanized rubber

Unvulcanized rubber for stamps production. Perfect for larger orders of one stamp design. Sold rolled up with a protective film between the layers.
Unvulcanized rubber is easy to make permanent deformation under the influence of high mechanical stress. A rubber sheet of appropriate size should be inserted into the matrix board with the desired stamp design, then pressed with a press to obtain an imprint and put to a vulcanization process to fix it.
