 Polymeric
MDI |
|
|
|
It is dark
brown liquid
sold in 250Kg
drum by packing
unit. Polymeric
MDI is a big
molecule formed
from many MDI
molecules. There
are three types
of polyurethane
made from Polymeric
MDI; semi-hard
foam, hard foam.
They are called
foam because
they have bubbles
in the inner
part.
Soft foam is
very soft and
immediately
comes back to
the original
shape when it
is altered.
Therefore soft
foam is mainly
used for parts
of cars.
Contrary to
soft foam, hard
foam is very
solid that it
doesn't come
back to its
original shape
when it is forced
to alter. Since
the hard foam
has insulation
effect, intercepting
the flow of
heat, it is
mainly used
for refrigerator,
synthetic lumber,
reefer container
and insulation
of architecture.
Semi-hard foam
has property
of both soft
foam and hard
foam. Semi-hard
foam, with its
superior shock
absorptive property
and touch is
used mainly
for parts of
cars and furniture.

| Monomeric
MDI |
|
|
|
 |
There are two
types of Monmeric
MDI, white solid
and transparent
liquid. When
the temperature
is below -21℃,
it is in the
state of white
solid and transparent
liquid between
38~45℃. It is
composed of
one MDI molecule
and sold in
250Kg drum by
packing unit.
It must be kept
in -21℃ or between
38~45℃, because
the original
property changes
according to
the storage
time and temperature.
Monomeric MDI
has the highest
degree of purity
among MDI and
it is used for
elastomer, the
shoe sole and
spandex of women's
garments as
well as synthetic
leather, waterproof
coating material
and adhesive. |
| Modified
MDI |
|
|
|
It is light
brown liquid
denaturalized
to be handle
easily by keeping
Monomeric MDI
liquid in the
high temperature
There are three
products denaturalized
from Monomeric
MDI and it is
sold in 250Kg
drum by packing
unit. Modified
MDI is used
for adhesive,
electromagnetic
coating material,
air filter of
cars as well
as sports shoes,
tennis courts,
medical equipments,
etc. |
 |
| Special
MDI |
|
|
|
 |
There are four
colors of liquid
in Special MDI;
brown, dark
brown, light
brown and transparent
liquid. It is
specially manufactured
to measure up
to the characteristics
of consumers
such as purpose
of use, ets.
It is mainly
used in the
special areas
such as interior/exterior
materials of
cars, building
and medical
field. Brown
liquid among
Special MDI
is mainly used
in soft foam
that it immediately
comes back to
the original
shape when it
is altered.
Therefore, it
is used in car
interiors such
as car seat,
head rest and
sound-absorbing
matrials as
well as mattress,
furniture, etc.
The brown liquid
is used for
seat back, head
rest and seat
cushion of cars,
furniture and
mattress. Dark
brown liquid
is used for
binder, light
brown liquid
for roof water
proof materials
and transparent
liquid for interiors/exteriors
of cars such
as handle, bumper,
spoiler, etc.
