collaboration
between players across the value chain
(SDG 17, Partnerships for the Goals).
SABIC helps customers tap the full
potential of its sustainable materials,
with complete support from design
for recycling and material selection to
tests and regulatory compliance.
While this opens new markets, it contributes
to partners' net zero carbon
goals and accelerates the transition
of the plastics industry to a circular
economy. In existing applications of
glass-filled PBT, such as in consumer
electronics and automotive (Figure
2), the new LNP™ ELCRIN™ iQ
compounds with pre-consumer recycled
glass fibres can be used as a direct
drop-in replacement without the
need for design changes or modified
tooling.
In addition to their improved sustainability
profile, these materials deliver
good structural performance, excellent
impact strength and high heat resistance
(Table 2).
As a non-halogenated and bromine-free
formulation, the WF0061XPiQ
compound also provides UL94
V-0 rated flame retardancy at 0.8 mm
for thin-wall applications and a UL
746C F1 rating for potential outdoor
applications.
Conclusion
LNP™ ELCRIN™ pre-consumer recycled
glass fibre-reinforced PBT compounds
offer an effective lower-carbon
value proposition for enhancing the
sustainability of a wide range of demanding
applications. Compared to
virgin PBT materials with virgin glass
fibres, they combine a high overall
recycled content and reduced carbon
footprint with equivalent performance
properties.

* Commercial TDS in preparation
Standardised third-party certifications
such as according to SCS Global and
UL 2809 validate each compound's recycled
content in resin and glass fibres,
which gives manufacturers a measurable
basis for achieving ambitious sustainability
targets.
