Rubber mixture – raw rubber is the non-vulcanized product which goes in the pressing, extrusion technological flow, in order to obtain the final components of vulcanised rubber.
Depending on the use and characteristics of the final rubber parts, they are grouped as follows:

• – rubber mixture – raw rubber – EPDM, offers vulcanized products a good ageing resistance and good resistance to 130 ° C temperatures
• – rubber mixture – raw rubber – SBR, used in general fields at the temperature range of -30…70°C.
• – rubber mixture – raw natural rubber – offers good abrasion resistance.
• – rubber mixture – raw rubber – nitrile, nbr – offers parts a good resistance to oils and petroleum products.
• – rubber mixture – raw rubber, neoprene – has a good resistance to oils and rubber ageing.
• – rubber mixture – raw rubber, silicone – offers very good resistance to high temperatures of +300°C.
• – rubber mixture – raw rubber, Viton – has a very good resistance to oils and high temperatures, +300°C.
