Advantages
of Polyurethane
Polyurethane
(or urethane) elastomers are one member of a large family of elastic
polymers called rubber. Unlike other members of the rubber family,
urethanes are liquid and can be molded into any shape or size. You
are only limited by your imagination.
Special
Properties of Polyurethanes
- Hardness
-
Polyurethanes can be compounded in a very wide range of hardnesses
from 10A durometer (like gelatin) to 85D+ (harder than a bowling
ball).
- Versatile
Designs
-
When using polyurethanes, possibilities are limitless. Materials
can be used alone or bonded to metal or plastic substrates and/or
inserts may be molded into it.
- Abrasion
Resistant
-
Polyurethanes often outperform rubber, plastic or metals in
many severe wear applications.
- Impact
Resistant
-
With even the hardest urethanes, you can achieve significantly
better impact resistance than plastics and composites.
- High
Load-Bearing Capacity
-
Compared to other elastomers of equal hardness, polyurethanes
have a greater load-bearing capacity.
- Chemical
Resistance & Corrosion Resistant
-
Urethanes offer excellent resistance to a wide range of chemicals,
oils and greases.
- Machinability
-
Harder formulations can be drilled, tapped and machined like
metal; softer materials can be ground.
- High-Flex
-
Urethanes allow for long-life parts under repeated flexing.
- Low
Temperature Environments
-
Polyurethanes maintain flexibility in low-temperature environments.
- Electrical
Properties
-
Most compounds offer a combination of electrical properties,
such as dielectric strength, dielectric constant, resistivity
and power factor.
- High
or Low Friction Formulations
-
The co-efficient of friction can be changed by modifying the
formulations. Dry friction is low in harder materials and high
in softer materials. Harder materials work well as slides. Softer
materials are ideal for feed or drive rollers and wheels.
- Noise
Abatement
-
Polyurethanes make excellent sound-deadening and anti-vibration
materials.
- Inserts
-
Polyurethanes can be bonded to a wide variety of materials including
steel, aluminum and most plastics.
- Colors
-
Almost any color under the rainbow is possible.
- Tooling
Cost
-
As a liquid cast material, tooling costs are very low--significantly
less than making metal molds.
- Weight
-
Polyurethanes can be used to reduce a part's weight by up to
50%.
- Quick
Prototypes
-
Molds can often be produced from existing parts, and different
materials can be tested to find the optimum formulation for
YOUR application.
- Flexible Production
-
Production from one part to thousands, sizes from several grams
to hundreds of pounds, are possible with urethane.
