Why use Powerflex?
Polyurethane has been with us as a specialised plastic for some
thirty years. However recent advances have now made it possible to
engineer very special properties into this exciting material. Suspension
bushes are some of the most highly stressed components fitted to a
motor car. They undergo enormous strains and in the most arduous of
conditions with no maintenance or lubrication.
The material they
are manufactured from is a rubber compound containing natural products
which deteriorate with age. It becomes softer and more pliable,
resisting the forces placed on it less and less. Therefore allowing more
and more movement of suspension components and offering less and less
control over the suspension geometry.
This in turn causes
accelerated tyre wear, braking instability and poor handling. This is
the single biggest reason you can instantly tell the difference driving a
three year old car compared to a showroom new one. However even new
cars will benefit from POWERFLEX bushes because of their superior design
they offer much more effective control of the suspension components to a
much greater extent than normal rubber items.
POWERFLEX for
prolonged tyre life.With the technological advances in this material it
has been possible to overcome the common problem associated with harder
bushes which is increased noise. By correctly engineering the
polyurethane compound, bushes can be made 25-30% stiffer than new rubber
items but with exactly the same noise absorbing properties.
