The halogen free polyamide
for demanding applications
Halogen-free
flame retardants for a
brighter future
Our mission at DSM is to create brighter lives for people today and for
generations to come. In the consumer electronics industry, the market requires
elimination of hazardous substances, as well as strong consumer demand
for materials and processes that are more environmentally responsible. A key
focus area is the elimination of halogenated flame retardants.
Innovation
The 3C industry – computer, consumer
Halogen free substances
Stanyl ForTii entirely eliminates the use of
and communication electronics – is an
enormous and growing sector based on
constant innovation, short design cycles,
and a trend of decreasing size while
increasing functionality. At the same time,
regulatory requirements are becoming
more demanding.
halogens, and is one of the products in
DSM’s portfolio of Brighter Living solutions.
In addition to an extensive halogen-free
portfolio, the DSM portfolio includes
recycle-based materials, bio-based
high-performance polymers, hazardoussubstance-free materials, as well as
materials that extend a product’s
serviceable lifetime, provide signicant
reductions in weight or friction, and help to
deliver a low or neutral carbon footprint.
Stanyl® ForTii™ is a high temperature
Polyamide 4T, available in halogen-free
and red phosphorous free UL94-V0
flame retardant grades, that delivers
exceptional high temperature performance,
high stiffness and low moisture absorption.
Partnership
We developed Stanyl ForTii in close
cooperation with the leading electronics
Original Equipment Manufacturers
(OEMs) and Tier 1 connector and socket
manufacturers. This industry has a strong
need for high-quality engineering plastics
that can withstand the increased heat and
mechanical requirements placed on them
due to the integration and thinnovation
trends driving the industry. DSM is uniquely
positioned to support these customers.
In addition to creating sophisticated
engineering plastics that provide them with
greater design freedom, we also support
our customers with complete application
development support.
Flame retardant plastics are
essential in today’s electrical
and electronics applications,
but how can they be made more
sustainable?
Stanyl ForTii delivers UL94-VO
flame retardance down to
0.2 mm in combination with
exceptional high temperature
performance, high stiffness,
low moisture absorption for
good dimensional stability.
Additionally it meets the Glow
Wire Ignitability Temperature
(GWIT) specifications, and also
supports lead-free soldering.
It helps our customers to comply with the
EU’s Restriction of Hazardous Substances
(RoHS) and the Waste Electrical and
Electronic Equipment (WEEE) regulations,
and also supports lead-free reflow
soldering.
Stanyl ForTii entirely
eliminates the use of
halogens, and is one of
the products in DSM’s
portfolio of Brighter Living
solutions.
Beyond electronics
Stanyl ForTii’s balanced profile
enhances design and
performance of key
applications in the automotive,
white goods, lighting and
medical segments, as well
as in electrical & electronics.

Stanyl ForTii: a proven
halogen-free perfomance
plastic for demanding
applications.
High Performance
Stanyl ForTii is a high-performance
polyamide ideal for use in injection-molded
consumer electronics parts. Applications
where the material has already proven its
reliability include connectors and sockets
for e.g. DDR DIMM and SODIMM, card
connectors, SATA or backplane, i/o and
FPC, desktop and server SMT DDR3 or LED
packaging.
Stanyl ForTii offers a unique balance of
high melt temperature (325°), high glass
transition temperature (125°), high stiffness
and very low moisture absorption.
It combines exceptional toughness and
stiffness with high strength before and
aer reflow, providing higher application
reliability values than PPS and liquid crystal
polymers (LCP).
Properties
Stanyl For Tii’s exceptional material
properties outperform the traditional
plastic materials used in electrical and
electronics applications. Its flexural
strength and toughness solve the
mechanical issues associated with LCPs,
while its high strength at weld lines
resolves issues associated with cracking.
Medical devices
- Low moisture absorption
- Excellent temperature,
mechanical and electrical
performance
White Goods
- High dimensional stability
- Supports high temperatures
in SMT
- No cracking at weld lines
- Easy and robust processing
- Glow wire performance
Lighting
- Excellent heat aging
- High initial reflectivity
- Strong UV and light resistance
Stanyl ForTii withstands
even the most demanding
SMT applications.
Industry trends
It supports the industry trends of
miniaturization and thinnovation with
outstanding reflow capability, and can
withstand even the most demanding
warpage requirements to surface mount
technology (SMT) applications.

Low warpage
At reflow temperatures, its stiffness and low

LCP/PPS blends. Stanyl ForTii also provides
excellent electrical performance, including
a comparative tracking index (CTI) of 600V
(performance level category 0), a low and
stable dielectric constant, and no ionic
migration at DC currents

Graph above shows the warpage and in

and LCPs. Especially when going from
halogenated PCBs to halogen free PCBs this
warpage at reflow temperatures of 260˚C
becomes crucial. The CTE delta a & a’ of PA4T
to PCBs is lowest.
High stiffness, low moisture absorption
Stanyl ForTii is well-suited to the
requirements of electronics. Its high stiffness
and low moisture absorption classies it
in the second best moisture level for any
application according to IPC/JEDEC J-STD
020D. Several customer products in moisture
level one have also past this test.
