Basics
The continual challenge for many industries served by
the chemical industry, however, is that traditional biobased
products don’t perform as well as the petroleum-based
products developed during the past 50 years. In the plastics
industry, specifically, performance is critical for durable goods
because materials have a long development time and are used
in products with a long product life. This adds to the burden
of finding new and better approaches today to be incorporated
into future downstream uses.
It is clear that the chemicals and plastics industry needs a
solution that provides a sustainable portfolio of products. The
solution must provide a better performing, more productive
and sustainable future for everyone — a new category of
solutions to deliver products that exceed performance of
petrochemical-based products and to do so with a smaller
environmental footprint.
Elevance Renewable Sciences, Inc., a high-growth specialty
chemicals company, is leading the industry by introducing
game-changing solutions that build on the Brundtland
Commission’s definition of sustainability and marry it with
performance that exceeds what’s been possible before. We
believe the way to become more sustainable is to develop
products that use fewer resources in the manufacturing
process and perform better. That’s where Renewicals
comes in.
Renewicals are a breakthrough category of novel products,
building blocks and ingredients that enable performance
impossible until now. Renewicals mark a paradigm shift in
the way companies are addressing industry and consumer
demand for improved performance and sustainability,
enabled by renewable feedstocks and advanced sustainable
manufacturing processes.
At Elevance alone, we provide two examples of how
Renewicals are changing the game for the chemicals and
plastics industry.
Inherent C18 Diacid is a mid-chain length, biobased diacid
that facilitates the creation of more than a dozen new base
polymers that can result in more than 100 new compounds
or formulations. Inherent C18 Diacid enables producers of
polyamides and polyurethanes to significantly expand their
portfolios with cost-competitive products that demonstrate
performance not possible from products made with more
common, shorter-chain diacids.
C
For example, Inherent C18 Diacid will allow polyamides to
M
enter new automotive and electronic applications that demand
better hydrolytic performance, improved optical properties
Y
and greater material toughness or flexibility. Using Inherent
CM
C18 Diacid in polyester polyols enables the creation of new,
MY
previously unattainable pre-polymers, helping polyurethane
manufacturers create polymers with exceptional solvent
CY
resistance, hydrolytic stability, optical clarity and toughness.
CMY
These high-performance, differentiated materials are suitable
K
in market segments such as automotive. Their use reduces
automotive weight, which improves car fuel efficiency and the
environmental footprint of transportation.
Another example is that Inherent C18 Diacid makes a
tougher GMA (glycidyl methacrylate) acrylic for powder
coatings. When the C18 diacid is used as the system
crosslinker in GMA powder coatings, the resultant coating has
twice the impact resistance as that of the incumbent diacid
and improved flexibility due to the longer, more elastic C18
methylene chain. As a result, this reduces the need for service
and repair, and improves the overall efficiency of equipment
use while extending equipment life.
Elevance is making Inherent C18 Diacid, also known as
octadecanedioic diacid or ODDA, using a unique and efficient
production process and materials produced from its worldscale
biorefinery in Gresik, Indonesia — the first based on
Elevance’s proprietary metathesis technology. The process
allows for the purity required for demanding applications like
polymers and is a solution that is cost competitive with other
specialty diacids in the marketplace. A mid-chain diacid,
Inherent C18 Diacid enables performance attributes not
possible by more common, shorter chain diacids.
Conclusion
Engineering polymer and plastic formulator customers can
now add biobased products with enhanced performance to
their portfolios, expanding their supply chains while achieving
their business and sustainability goals. The industry can also
make a difference and do things that have never been done
before — today. Join us in the Renewicals movement and help
transform the industry to meet the needs of the nine billion
people who will live here. It promises to be an exciting and
more sustainable future for everyone.
