The highly competitive consumer electronic
industry is also very fast moving, as IT and
telecom products continue to add more features
and turn more towards wireless. Computer and
printer makers, faced with the tough challenge
of selling more hardware in a saturated market,
are expanding competencies. The global mobile
device market has achieved its third consecutive
quarter of yoy growth exceeding 100%, rising
134.6% yoy to 8.4 million units in 2005. Mobile
phones have seen a quantum jump in the features
offered as they double up as MP3 players,
digital cameras, personal organizers, etc.
A shift to converged technology with basic
personal information management (PIM) functionality
is exerting pressures on companies to develop
a niche competency that will rehabilitate
growth in the handheld device market. These
emerging applications exert fresh demands
on materials and engineering, as the combination
of increasing functions demand more memory
space. Solid-state memory devices are shrinking
in size and will soon be small enough to fit
into the compact form factor of a mobile phone.
Demand from traditional hard-drive outlets
such as desktop and laptop computers will
get dwarfed by this demand and provide a significant
opportunity for plastic component suppliers.
Analysts estimate that by early 2006, 25 million
hard drives will be used in cell phones, which
will see a quantum jump to 500 million by
2010.
The first example of a mobile phone incorporating
a hard drive is the SGH-I300 from Samsung
Electronics (Seoul), which comes with 3 GB
of storage on a disk similar to that used
in Apple's iPod mini.
Mitsui Chemicals' Grade PL8001 is a new grade
of thermoplastic polyamide resin (Aurum) that
targets hard-drive applications. The grade
contains carbon nanotube filler and boasts
excellent antistatic properties, as well as
superior processability.
Mitsui's Chemicals' cyclic olefin copolymer
is finding increasing application as the lens
material in mobile phones that are fitted
with cameras, prompting a capacity increase
of 600 tpa to 3400 tpa by the end of 2005.
Besides memory and optics, ETP suppliers are
developing compounds to boost the performance
of voice communication in mobile phones. High-dielectric-constant
compounds used so far suffered from high specific
gravity, difficulty achieving dimensional
precision due to large shrinkage ratios and
problems with thin-wall molding. Polyplastics
has developed a series of high-dielectric-constant
compounds based on PPS and LCP that employs
a ceramic filler, specifically targeting compact
mobile phone antennae. The compounds can also
withstand lead-free solder temperatures.
A polyamide copolymer (PA9T) of terephthalic
acid and nonane diamine from Kuraray with
heat resistance up to 300°C can also withstand
lead free solder temperatures, with low water
absorption-less than 1% compared with 2.6%
and higher for competing materials. Kuraray
plans a capacity increase from 3000 tpa to
4000 tpa by the end of 2005 in response to
increased demand for electrical and electronic
applications, including mobile phone connectors.
The other key drivers of this market are globalisation
of the market, recyclability and legal issues.
In addition to global demand, regional legislation
has also plays a large part in determining
the grades specified by OEMs. Legal issues
continue to drive parts design and materials
choice as issues such as forced recycling
and strict limits on lead and brominated flame
retardants are similar across regions.
The WEEE (Waste Electronic and Electrical
Equipment) legislation that takes effect in
the European Union in July 2006, requires
OEMs to collect and recycle their products
at increasingly high levels. Enforcement of
the WEEE along with European laws strictly
limiting the use of lead and some flame retardants
has led many OEMs to shift entire product
lines to grades that are compliant with European
law, rather than managing multiple inventories
for different geographic markets.
The E.U.'s RoHS (Restriction on Hazardous
Substances) laws place strict limits on lead
and several other materials often used in
electronics manufacturing, forcing a reconsideration
on lead soldering. The legislation is complicated
as it does not stipulate that no lead can
be used; it does dictate that only very low
levels of lead are permitted in each part
or component. Some equipment, including servers,
compliant pin connectors, and light bulbs
likely will be given exemption from RoHS.
