RIBTYPE RUBBER TYPE MATERIALS
NATURAL RUBBER: Most RIBtype® is made from natural rubber. While others color their rubber type gray, ours has an orange face with gray ribs to set it apart from other brands. Natural rubber is best for general purpose use with alcohol and water-based inks. It is available in standard 50 durometer or soft 30 duro.
BLACK BUNA: This oil and acid resistant material is best for use with oil-based inks or when the type is exposed to petroleum products. It is available in hard 90-durometer, standard 50-duro or soft 30-duro buna. Black Neoprene RIBtype is very similar to buna. It is oil and acid resistant and makes excellent imprints. It is frequently used in place of 50-durometer buna.
GREEN PVC: This oil and acid resistant material is sometimes recommended for printing small text on plastic or film and for printing on abrasive surfaces such as Tyvek or brake shoes.
SILICONE: This blue-and-white material is for use with thermal ink-transfer printers and for hot stamping. It has a high heat tolerance and is much less expensive than metal type.
