Synthetic rubber is used in roller manufacture: a complex mix of
natural rubber and various chemicals that achieve stability and
elasticity through the vulcanization process. It is the raw rubber
that gives the rubbery material its basic characteristics.
To this are added the vulcanisation agents for the subsequent
vulcanisation process. Plasticisers (fluid oils) play a major role
as they - along with the extenders and the vulcanisation agents -
determine the subsequent degree of hardness of the material. The
more plasticisers that are added, the softer the rubber after the
vulcanisation process.
- If possible, do not expose rollers to direct natural or
artificial light.
- The special paper that the rollers are delivered in prevents
light penetrating and therefore helps retain the rubbers'
characteristics. For this reason, do not remove the paper before
installing the roller in the press.
- Always put the roller with its pivots on a frame support:
Putting it down directly onto the rubber can result in permanent
deformations (pressure marks).
- Store rubber rollers in a cool and dry place.
- Under certain circumstances ozone causes microscopic
scratches on the rubber surface. For this reason do not store
rollers in the vicinity of motors or other electrical
devices.
