Ultrason ® Dimension –
a new PESU blend
If thermoplastics are to keep their properties in a hot environment,
there is a conflict of aims, because polymer materials
showing good dimensional stability and attractive mechanical
performances at high operating temperatures are often difficult
to process in injection molding – and vice versa. Ultrason ®
Dimension, a new glass-fiber reinforced blend based on polyethersulfone
( PESU ), is the solution to this problem.

Fig. 1: The modulus of elasticity of Ultrason ® Dimension achieves a level
of over 10,000 MPa at 120 °C.
Ultrason ® Dimension has three key
properties:
the modulus of elasticity at 120 °C is above 10,000 MPa
( Fig. 1 )
the CTE between 23 °C and 200 °C is below 65 · 10 -6 1 / K
( Fig. 2 )
the volume growth after storage in hot oil ( ATF ) at 140 °C
is less than 2 %

is characterized by a virtually linear and largely isotropic flow.

Ultrason ® Dimension – metal replacement
in customized applications
Ultrason ® Dimension benefits from a modified PESU formulation.
So the flowability is significantly increased without negative
effects on the normally high dimensional stability of the amorphous
matrix. Because of the improved flowability the glass-fiber
content of the compound could be increased. However, the melt
viscosity is still around the same as that of Ultrason ® E 2010 G6,
a polyethersulfone with 30 % glass-fibers which has a wide
range of applications.
Ultrason ® Dimension also offers the inherent flame retardance
typical of PESU – it has a UL94 rating of V0 without addition of
flame retardants ( acc. to in-house tests ).
Ultrason ® Dimension therefore represents a particularly economic
alternative to metal and other high-temperature plastics
such as polyether ether ketones ( PEEK ), e. g. with regard to raw
material prices and greater ease of processing. In particular, it
can replace aluminum parts in vehicles, e. g.:
parts in contact with hot oil
pistons, switches, gear wheels
+ outstanding stiffness
+ very good dimensional
stability
+ ease of processing
Since Ultrason ® Dimension is also suitable for components in
contact with food, applications such as parts of coffee machines
in constant contact with hot steam are possible.
