Sabic launches massbalanced
renewably-sourced
polycarbonate copolymer
Sabic has introduced LNP ELCRIN EXL7414B
copolymer, the company's first
mass-balanced, bio-based polycarbonate
copolymer to help advance the consumer
electronics industry's net-zero carbon
emissions goals. It is formulated with over
50 percent bio-based content from waste
materials and a preliminary Sabic internal
assessment indicates that each kilogram of
the new bio-based resin provides two kilograms
of CO2 reduction as compared to its
fossil-based counterpart. In addition to lowering
the carbon footprint by reducing the
use of fossil-based feedstocks, Sabic's LNP
ELCRIN EXL7414B copolymer resin delivers
exceptional performance for demanding
electronics applications. It uses a non-brominated,
non-chlorinated flame retardant
formulation that meets the UL 94 V0 standard
at 0.6 mm.
The resin's excellent processability
enables ultra-thin part designs that save
weight and space, and off ers opportunities
for shorter cycle times and higher
throughput vs. standard PC. The new
material also provides excellent low-temperature
ductility (-40℃) for impact
strength when a device is dropped, and
good chemical resistance to withstand ultraviolet
(UV)-cured painting.
Dupont expands Delrin family
DuPont has launched five new grades in its
Delrin Renewable Attributed product family.
These products can be used in medical and
food contact applications. Long-standing
distribution partner Biesterfeld Plastic will
distribute the POM homopolymers in large
areas of the EMEA region as well as in Brazil.
The new grades include Delrin RASC655
and Delrin RASC698, both designed specifically
for medical requirements and which
form part of the Special Control group at
DuPont. All products with this designation
undergo extensive testing, off er a high degree
of production control and satisfy the
medical sector's standard regulatory requirements,
for example USP Class VI and
ISO 10993. Both grades off er outstanding
mechanical properties and an exceptionally
low friction coeff icient. This makes them
ideal for demanding medical applications
such as wearables, inhalers, pumps and
other products. DuPont is also introducing
three new grades suitable for food contact
in line with EU Directive 10/2011 - Delrin
RAFG511DP, Delrin RAFG500P and Delrin
RAFG100. All three products have a long
lifetime and high fatigue resistance across
a broad temperature spectrum, especially
at low temperatures. This makes these new
materials especially suitable for food packaging
and potable water applications.
Braskem introduces two new
FDA-approved food contact
recycled PP grades
Bioplastics and polyolefins producer
Braskem has developed two new circular
PP grades with recycled content based on
post-consumer waste. Both grades have
been approved for a wide range of U.S.
Food and Drug Administration (FDA) food
contact applications, including consumer
packaging, caps and closures, housewares,
and a wide range of thermoforming applications.
According
to Braskem's North America
sustainability director, Geoff rey Inch,
the announcement is another milestone in
Braskem's journey to a carbon-neutral circular
economy,
" These developments will also keep us
on track to reach our goals of providing
300,000 tons of thermoplastic resins and
chemicals with recycled content by 2025
and one million tons of thermoplastic resins
and chemicals with recycled content by
2030, " he said.
To reach these goals, Braskem has embraced
both mechanical and advanced recycling
solutions and to that end has sought
Braskem's new PCR polypropylene grades can
be used in a wide range of U.S. Food and Drug
Administration (FDA) food contact applications
where PP is used today.
to engage with and invest in partnerships
with other members of the value chain. In
this way, not only is Braskem promoting
mechanical and advanced recycling, but
also the company is supporting the increased
production of high-quality recycled
material. These initiatives are aligned with
Braskem's feedstock diversification strategy
and its macro goals of expanding the circular
economy concept in the plastic chain
and becoming a carbon-neutral company
by 2050.
According to Braskem, its new thermoforming
PP grade contains 25% post-consumer
recycled content and meets the requirements
for certain FDA food contact
applications, including high-temperature
packaging.
The new caps and closure grade also
contains 25% post-consumer recycled content
and is best suited for injection moulded
caps and closures in segments such as
food and beverage, health, hygiene and
cosmetics.
Teysha
Technologies
collaborates on
the development
of bioplastics for
the agricultural
industry.
Teysha partners with
agricultural industry
Biopolymer innovator Teysha Technologies
is working with the crop research organisation
NIAB to research, test and develop
bioplastics for the agricultural industry in
the UK. The opportunity will allow Teysha
to expand as the startup further commercialises
in the UK, utilising the facilities and
expertise at the Eastern Agritech Innovation
Hub near Cambridge. The Innovation Hub,
an NIAB incubator facility, is a focal point
for research and development into reducing
or valorising waste in farming. Teysha will
therefore expand the remit by developing
and testing new sustainable materials and
bioplastics to tackle growing plastic pollution
as well as investigating waste feedstock
options within British agricultural operations.
The first innovation to be delivered
from the new Teysha laboratory, based at
the Hub, will be a series of new polyester
