We have over 25 years experience in rubber coverings.
Covering rollers is how we got our start in the
roller business.
We can cover your new idler or any existing roller with any one of these
elastomers:
EPDM:
EPDM offers you excellent ozone resistance and chemical resistance.
It also has above average abrasion and dent resistance. Our EPDM's feature
a balance of physical properties and chemical resistance which makes
for their ideal use in a wide variety of rubber roller applications.
NITRILE:
or (NBR) or (BUNA) is the work horse of roller applications. It's great
physical properties makes it a cost effective covering for many run-of-the-mill
nip, idler, pull roll applications. Also, NBR's chemical resistance
make it great for a wide variety of applications.
NITRILE PVC:
Like our EPDM Silicone blends, here is another rare instance in which
the combining of two compounds results in the best properties of both.
Used in many printing applications because of its balance of physical
properties and resistance to many chemicals.
Nitrile PVC offers the following specific properties: 1. Resistance
to aliphatic hydrocarbons (oil base inks) 2. Improved ozone resistance
over Nitrile 3. Improved abrasion resistance over Nitrile
CARBOXYLATED NITRILE:
This compound is similar to nitrile rubber. However, the polymer back
bone has been chemically modified with carboxylic acid. The result is
a rubber with outstanding abrasion resistance and chemical resistance,
far superior to that of traditional Nitrile.
HYDROGENATED NITRILE (HNBR):
This compound has been developed to compete head to head with polyurethane.
HNBR surpasses conventional NBR compounds in four areas:
- Mechanical properties
- Dynamic properties
- Oil and fuel resistance
- Heat resistance. Physical properties are maintained over the range
of temperatures, as opposed to urethane elastomers which degrade
proportionately to changes in temperature.
- Improved abrasion resistance. Improved tear and chunk out
resistance.
- Retention of toil geometry. The initial higher cost is repaid to you
over and over again in improved performance and long term savings in
maintenance and downtime costs. Head to head trials have shown our HNBR
lasts three to five times longer then typical roll coverings.
HYPALON:
This compound is the mule of elastomers. Outstanding abrasion and cut
resistance coupled with excellent ozone, heat, and chemical resistance
make it one tough producer in many roller applications such as corona
treating, laminating, coating and cast film nip rolls.
NEOPRENE:
Once the work horse of the industry, it is now not called upon as it
once was. The evolution of some of the other compounds shown here has
led to the decline of neoprene's use in some applications. However neoprene
is still the compound of choice for some applications. Neoprene rolls
offer good tensile, cut resistance and low compression set.
NATURAL RUBBER:
The foundation compound that all coverings came from, natural rubber
still has some outstanding qualities that have kept it a viable covering
for some applications. It has excellent load bearing properties, tensile
strength, abrasion resistance, resistance to polar solvents (esters
and ketones) and is available in extremely hard durometers which are
used in both the paper and textile industries.
FLUOROELASTOMER (VITON):
Offer excellent heat resistance, excellent fuel oil and chemical resistance
and excellent abrasion and cut resistance. The place for this covering
always justifies the cost. Uses are quite often where nothing else will
work. In the correct use this compound is awesome.
MILLABLE URETHANE: ETHER
Urethanes offer extremely good wear resistance, with excellent solvent
resistance. Call us and we can formulate a compound for your particular
need (either a polyester or polyether).
MILLABLE URETHANE: ESTER
Urethanes offer extremely good wear resistance, with excellent solvent
resistance. Call us and we can formulate a compound for your particular
need (either a polyester or polyether).
CORONA TREATER:
Our corona treater roller covering is a hypalon covering specially designed
to withstand the rigors of its environment. This compound has outstanding
dielectric strength which enables it to insulate against the high voltage
at the treater station. Although several materials have been tested
for voltage corona discharge, our compound stands up better than silicone
which is easily cut, and ceramic coatings which add significant weight
to the rollers requiring auxiliary drive units.
SILICONE:
Silicone rubber is definitely one of a kind The important characteristics
are heat resistance and release, or the inability for things to stick
to it. We have specialized in silicone since the beginning. Although
our industrial grades are great producers, our other grades such as
high release, thermally conductive, FDA approved and anti-static are
superior in their particular applications and have become national he
roes! Important characteristics:
- Outstanding resiliency
- Low coefficient of friction (high release)
- Heat resistance up to 500 F
EPDM SILICONE:
A unique blend of EPDM and Silicone that combines the best properties
of the two compounds. The EPDM-Silicone blend is well suited for applications
where a balance of heat, release, strength and chemical resistance is
required. In some applications, straight silicone or EPDM's physical
properties don't measure up to the job at hand but the two compounds
combined can often measure up better than either one alone.
ANTI-STATIC ROLLER COVERINGS:
Our family of anti-static coverings are available in five different
elastomers. Anti-static rollers are used for two main problems:
- Contaminants (such as lint and dust) sticking to the surface of the
rollers or substrates.
- The danger of explosion or fire resulting from sparks caused by
static build up. The conductive compounds are offered in two types.
Black compounds which have the greatest conductivity through the
addition of carbon blacks but the basic dynamic properties of the
compound can be effected slightly. The other are non-black compounds
which have a reduced resistivity but the dynamic properties are not as
effected.
