Polychloroprene Rubber Video Lecture - Chemical Engineering

good morning students I welcome you all
for these groups notably rubber under
the Moose elastomer technology for your
class now
Lauro cream is also known as poly
chloroprene of the object have looked
during the nineteen thirties extra
members it answered robert developed an
oil resistant substitute for natural
problem
there are various good teachers good
chemical resistance hydrants to aging
and low risk of blazing better resistant
higher cost that natural no this is the
negative side now this is the overview
let's see last of us are generally
leachate is going soft
now when retail customers do not become
plastic now elasticity of an elastomer
dramatically has defined by the degree
of cross-linking and this little
processes from vulcanization little
print is the common name for the organic
compound to roto-rooter man one of the
oldest type of sensitive referred is
flora prim this homopolymer of fluid
produced by radical emulsion
polymerization of to flora butadiene
one three all it is also called to grow
monthly no divine loading and the
polymer reduces the reactivity to many
oxidizing agents now in the case of
polymerization potassium wrap or
oxidizer which is the most frequently in
this region there are sulfur or mark
captain are used for regulating this
cell phone is behaving as the one and it
creates album features if the volume
will change to six hundred atoms which
improve the flexibility
but reduce their temperature resistance
the blue sir doesn't cut in sulfur
bridges but they're back volume will
stand we donated to the rest of the
transfer hitting-point you can see the
structures of w CR and TCR this CC are
the dumps now these are the structural
units off Robert right even seen in
different other volume is in
deliverables when we have discussed you
can have the trans and C's truss
structures this is this transcript is
shown the opposite will be the C
structure and is the one to third now
general properties are you print over a
polychloroprene of CR has good edging
characteristics e ozone layer
environment good edgy for weather along
with abrasion and place that England
states european has limited essence to
deterioration from exposure to petroleum
place with the dense an obstacle
mostly luster once either instead reduce
relation from exposure to petroleum mr.
Brigance or jobs now see our our product
rim is also offers resistance
refrigerants
silicone oils water also vegetable oils
and handles so there are there are
various properties combined with the
wide temperature range and moderate cost
accounts for the desirability in any
sillim addition but not effective in
many aromatic oils the office only
limited resistance to the melons
presence of the chlorine atoms in each
of the structural unit has implement
solving basic CR competence now there
are different properties are mentioned
over your which are in the presence of
the chlorine atoms they're highly polar
they have very low permeability
they can eliminate itself at higher
temperature so undergo the
self-organization
thus metal oxides are added to them
because of these effects as acceptance
then uh dwarfs die free properties that
not born of it
cooler subsidizing their structurally is
definitely increase levels since
oxidation and organization will take a
cause of death this slide and go to the
reflections like this is a reflection
scott you are currently watching a
recorded video now write down this
answers what are the violators of CR or
other robbers and what will be the
problem areas of
we'll move to the other side these are
various application market usually
travel used for gasket given jackass
saint-maurice tire sidewalls gasoline
roses etc also used as base wrestling
Highness's electrical insulation and
coatings many useful properties a
tourism the price typical morning
temperature is minus 35 degrees Celsius
to plus under diseases these are various
applications some of the applications
rather I am sure these are the
advantages so the comparison with
various raw different properties of
radius different promise they such share
the video file with you
these are the references
