Adhesives
Enhance Healing |
|
(NAPS)-Healing your skin may
be easier; thanks to a new technology that
may soon replace stitches and sutures.
Medical adhesives, such as
DERMABOND Topical Skin Adhesive, are now
being used in operating rooms and emergency
rooms to close wounds in a faster and less
painful way.
According to the Society of
Plastics Engineers, the procedure is four
times faster than administering sutures
and does not require painful injections.
To apply the adhesive, doctors
merely squeeze a sterile ampule while holding
the edges of the wound together. Studies
also demonstrate that the adhesive has superior
healing results.
“This is particularly important
for use in surgical procedures on the head
or face where scarring is an important consideration,”
said Dean M. Toriumi, M.D., associate professor
of facial plastic and reconstructive surgery
at the University of Illinois at Chicago.
Another medical adhesive is
currently being developed for use in the
home. LIQUIDERM liquid adhesive bandage
by CLOSURE Medical Corporation (Nasdaq:
CLSR) will soon be available for over-the-counter
use to treat minor cuts and abrasions.

From
Information Highways to Smoother Highways |
|
(NAPS)--There
could be good news for anyone who's ever
felt like driving over a computer. You may
already have.
Clever scientisits have found a way to
recycle old computers and use them to repair
roads.
Hundreds of thousands of pounds of discarded
computers are tossed out every day. Fortunately,
they can be ground down and the plastic
recycled to become a major ingredient in
a new pothole filler mix.
In the next five years, predict the experts
at the Society of Plastics Engineers, about
150 million computers can be recycled in
this way--enough to fill an acre of land
to a height of 4,000 feet.
Recycling hard drives and their housings
into roadways, it seems, can drive down
our need for landfills, helping preserve
the environment for all households.

Coming:
New Parts For Old People |
(NAPS)--Some
people may talk about a heart of gold, or
a nose for news or feet of clay, but in
the not-too-distant future, we may be getting
new body parts reproduced from old cells
using special polymers.
Other biodegradable
polymers may deliver chemotherapy and other
medicines directly to an area inside a body,
slowly releasing it over a period of weeks,
even years and then disappear.
Designers
of the first artificial heart, looking for
a long-life flexible material, selected
the polymer used in women's girdles.
It's still used today, 29 years later.
These new systems and
devices are just part of the work and thoughts
of Robert S. Langer, a 47-year-old professor
of chemical and biomedical engineering at
Massachusetts Institute of Technology. Langer
was honored recently at the Society of Plastics
Engineers annual technical conference.
After receiving SPE's
International Award, Langer presented in
his keynote speech, a series of slides depicting
changes in polymer technology. To the attendees--top
global professionals in the industry--this
is a common sight. However their attention
was heightened when Langer showed slides
of brain surgery as well as tissue engineering.
Ears, fabricated out of polymers, have human
cartilage cells distributed throughout the
mold. They are then implanted on the backs
of specially bred mice which lack the immune
system that might reject human tissue. The
host mice nourish the human tissue cells
as they grow around the polymer molds. This
will be used to grow noses as well as ears.
Extending this into the human realm, Langer
showed other slides of a 12-year-old boy
whose life was transformed by the plastic
chest implant that now protects his heart
and gives him a semblance of a normal childhood.

Recycled
Plastic Shows Up In Trendy, Seasonal Clothes
|
|
(NU)--What can you
do with the polyethylene terephthalate (PET)
plastic from recycled soda bottles? If you
pay attention to the labels when you're
shopping, you'll find that you can wear
it.
Manufacturers like Reebok, L.L. Bean,
Lands' End, Bass, Lee Jeans, Code Bleu and
Patagonia, to metnion a few, are using recycled
PET plastic for trendy, seasonal clothes.
For many years, the Society of Plastics
Engineers says, manufactureres have been
using recycled PET plastic as filler for
"down" jackets and sleeping bags.
But now it's also finding its way into T-shirts,
sweaters and shoes.
So look at the labels. You might find
that the fabric tops of your new Reeboks
are recycled plastic. And that soft fleece
Patagonia pullover is, too.
PET plastic can be transferred to polyester,
the main fiber in many of today's clothes.
Polyester is less expensive than virgin
cotton. And PET plastic is even less expensive
than virgin polyester.
Besides, recycling is "in" these
days. "People like to see what products
their recycled bottles come back in,"
a Society of Plastics Engineers spokesman
says.
Even before it's recycled, plastic is
one of our most earth-friendly materials.
It takes less energy to convert raw materials
to plastic. Plastic's light weight saves
fuel costs when transporting products to
market. And since plastic bottles resist
breakage, there are fewer losses during
shipment. That means lower prices for consumers.
But back to the clothes. In garments,
recycled PET plastic is breathable, wickable
and highly durable. And it's 100 percent
recyclable, so after you tire of that jacket
or pair of shoes, the plastic will find
yet another use.
It's also soft and feels much like a cotton/polyester
blend. "The recycled PET plastic T-shirt
that I have," the Society of Plastics
Engineers spokesman says, "feels like
all my other T-shirts -- I can't tell the
difference."

A
Few Facts About Plastics and Plastic Bottles
That May Surprise You |
|
(NAPS)--Did
you know. . . Plastic comes from nature?
It is a by-product of petroleum. There are
about 50 different varieties of plastic.
The experts at the Society of Plastics
Engineers point out that plastic bottles
and other packages help preserve our food.
In the U.S., plastics account for only
three percent of our energy consumption?
Plastic bottles gain popularity over heavier
packaging because plastics require less
energy to convert from raw material and
their light weight saves fuel costs required
to transport products.
The history of plastic goes back more
than 100 years? The first plastic, actually
cellulose nitrate, was introduced as a replacement
for ivory in billiard balls.
What distinguishes plastic from other
materials is its seemingly endless ability
to be molded, shaped, modified or diversified
to meet society's demands? For food packaging,
this may mean keeping moisture out, carbonation
in, or withstanding high temperatures. Virtually
all plastic bottles resist breakage, which
means fewer losses during shipment and lower
prices for consumers.
The use of plastic bottles reduces waste?
Americans have the best food delivery system
in the world, waste less food than most
other industrialized nations, and spend
a smaller portion of their incomes at the
grocery store.

Non-Sticky
Situation |
| (NAPS)--Almost
100 years after Charles Goodyear’s accidental
discovery of vulcanized rubber revolutionized
that industry, the science of plastics benefited
from a similarly unexpected turn of events.
Working in a laboratory in New Jersey, Dr.
Roy J. Plunkett was experimenting with gases
relating to refrigerants when he checked
up on a frozen, compressed sample of a polymer
called tetrafluoroethylene. The substance
had formed into a white, waxy solid.
The new polymer, polytetrafluoroethylene,
was discovered to be inert to virtually
all chemicals, giving it extremely slippery
properties. Seven years later, Plunkett
and DuPont received a trademark and dubbed
the material Teflon.
Today the "world’s most slipper substance"
is used to insulate data communications
cables, to lubricate the stainless-steel
skeleton of a Statue of Liberty, to coat
millions of non-stick pans and for thousands
of other applications.
In 1988, the Society of Plastics Engineers
honored Dr. Plunkett for his scientific
contribution in the area of plastics, presenting
him with the John W. Hyatt Award, named
for the inventor considered to be the father
of the U.S. plastics industry.
