Polyurethane is one of the
most versatile, toughest, abrasion resistant elastomers
available. Polyurethane is available as soft as Shore A
scale durometer 10, and hard as Shore D scale
durometer 90 . Cast Polyurethanes may be
processed to any desired color
Polyurethane may be cast into practically any shape,
size or complex geometry desired wheels, gears ,
orings, gaskets, tires, roller blades, skate boards are just
some of the many economical uses of tough, abrasion
-resistant cast polyurethane parts.
Polyurethanes can be formulated with
high-resistance to stresses and they tend to maintain shape
and mechanical properties after fatigue stressing.
Other advantages of cast polyurethane:
-
Cast Polyurethane maybe pigmented to
resist degradation by elevated atmospheric oxygen and ozone
atmospheric
concentrations. This makes them highly rugged when
used with electrical equipment producing ozone.
-
Cast polyurethanes are commonly used to
insulate or encapsulate.
-
Many cast polyurethane elastomers
compounds remain flexible
at extreme low temperatures and possess outstanding resistance
to thermal shock. Low temperature resistance of
polyurethanes make cast parts very practical in extreme arctic
conditions.
-
Cast Polyurethane parts can be made flame resistant by
incorporating flame retardants into their formulas.
-
Polyurethanes can be cast with
coefficients of friction varying from very low, for items
like bushings, bearings, or wear strips, or very high, for
items like tires or rollers.
In
general, designing for cast polyurethane is identical to
designing for any plastic,
molded or injection molded.
