Ultradur® (PBT )

Ultradur® is BASF’s trade name for its line of

partially crystalline saturated polyesters. This
line is based on polybutylene terephthalate and
is employed in applications demanding a high
performance level such as load bearing parts in
different industrial sectors. Ultradur® is out-
standing for its high rigidity and strength, very
good dimensional stability, low water absorption
and high resistance to many chemicals. More-
over, Ultradur® exhibits exceptional resistance
to weathering and excellent heat aging behavior.

Examples of subnames:
LUX Particularly high transparency to the radiation Letters for identifying reinforcing agents,
from Nd:YAG lasers and lasers of a similar fillers and modifiers
wavelength, e. g. diode lasers G Glass fibers
C Carbon fibers
K Glass beads
Technical ID M Minerals
Z Impact modifiers
The technical ID is made up of a series of letters and GM Glass fibers in combination with minerals
numbers which give hints about the polymer type, the
melt viscosity and the finish with reinforcing agents, Key numbers for describing the content of
fillers or modifiers. The following classification scheme reinforcing agents and fillers
is found with most products: 2 approx. 10  % by mass
