Engineering plastic
Engineering plastics
?are a
group of??materials that have better mechanical
and/or thermal
properties than the more
widely used?(such as?,?,??and?).
Being
more expensive, engineering plastics are produced
in lower quantities and tend to be used
for smaller objects or low-volume
applications (such as mechanical parts), rather
than for bulk and
high-volume ends
(like containers and packaging).
The
term usually refers to??materials rather
than??ones. Examples of engineering plastics
include?(ABS), used for?,??trim
and??bricks;?, used in?; and??(nylons), used
for??and?.
Engineering plastics have
gradually replaced traditional engineering
materials such as wood or
metal in many
applications. Besides equalling or surpassing them
in weight/strength and other
properties, engineering plastics are
much easier to manufacture, especially in
complicated shapes.
The global market
for engineering plastics in terms of revenue was
estimated to be worth $$45.2
billion in
2011 and is expected to reach $$76.8 billion by
2017.
Relevant
properties
[]
Each
engineering plastics usually has a unique
combination of properties that may make it the
material of choice for some
application. For example, polycarbonates are
highly resistant to impact,
while
polyamides are highly resistant to abrasion. Other
properties exhibited by various grades of
engineering plastics include heat
resistance, mechanical strength, rigidity,
chemical stability and fire
safety.
Research
mFaculty in the
Department of Plastics Engineering are active
researchers. The department maintains
an extensive lab facility allowing the
faculty to direct research in areas including the
following:?
•
•
•
•
•
•
•
•
•
Plastics Product Design
Plastics Process Development
Plastics Materials and Additives
Plastics Mold and Die Design
Elastomers and Rubber
Testing and Characterization
Computer-Aided Engineering
Plastics Recycling
Polymeric
Biomaterials
Other Research Initiatives
•
Technology commercialization takes
place within Commercial Ventures and Intellectual
Property
(CVIP), whereas the focus of
our economic development activities is with
entrepreneurs and early
stage companies
within Commercial Venture Development (CVD).
•
Nanotechnology research is creating
scientific breakthroughs at an amazing rate --
inventions that
hit the national and
international news almost daily. The promise of
nanotechnology will not be
realized
until lab-created inventions can be reliably
replicated and manufactured.

NSF Biodegradable Polymer
Research Center
The Biodegradable
Polymer Research Center (BPRC) functions to carry
out exploratory and
fundamental
research on biodegradable polymers to support the
technological interests of its
members.
The Plastics Engineering faculty works
closely with both industry and governmental
organizations on
plastics-related
research. Most research programs are developed
between faculty members and the
sponsoring company or organization.
Project sponsors define their specific needs, and
the faculty
member(s) develop a
proposal.
In such cases, a proposal is
developed with the assistance of the UMass Lowell
Office for Research
Administration, the
University's one-stop solutions provider for
managing research, budgets,
technology
research programs and technology licensing.
Mechanisms exist for conducting all
types of
research programs: from simple
short-term materials testing or consultations to
major multi-year
research projects.
