Rubber-Products

Application:

for production of gaskets and seals working statically in non-stretched status

Types of rubber sheets:

• SBR – for normal conditions and neutral water solutions,

• NBR – resistant against oils, fuels and fats,

• CR – higher resistance against atmospheric conditions and weak acids,

• EPDM – resistant against oxide, ozone, higher temperature and UV-radiation,

• NR – resistant against abrasion and tear-off

Versions:

• without textile plies,

• with 1 or 2 textile plies, strengthening the resistance against tear-off

• plain on front and bottom surface,

• with cloth-print on bottom surface

Standard dimensions:

Production of rubber sheets in dimensions and tolerances other than standard ones, is possible upon prior agreement.
