MX-Nylon has many properties that are superior to other conventional
polyamide resins and to other polymers.
- Higher
tensile and flexural strength and modulus
- Higher
glass transition temperature
- Lower
water absorption speed
- Excellent
gas barrier properties against oxygen, carbon dioxide and
other gasses.
Particularly,
the properties of higher physical strength, modulus, and glass
transition temperature and superior gas barrier properties
make MX-Nylon well-suited for engineering plastics for automotive
applications as well as food packaging – where gas permeability
is essential.

MX-Nylon's
higher physical strength and modulus make it the choice
for
durability. Improved durability coupled with its ability
to absorb vibration make it an ideal material for
certain automotive applications, such as door mirror supports.

MX-Nylon
Grade 6000 – an injection molding
and compounding grade with a low relative viscosity
and high glass
transition temperature is suitable for blending.
MX-Nylon Grade S6007
is suitable for both injection molding and extrusion molding.
This grade is the main grade for multilayer PET bottles
as a barrier material.
MX-Nylon
Grade S6011 has a similar molecular weight
and relative viscosity of grades S6007, but has been improved
for the processability of extrusion molding for sheets and
films used in thermoform containers and flexible packaging.
MX-Nylon Grade S6121
has the highest relative viscosity and molecular weight essential
to the extrusion of cast and blown films.

The other
major application is food packaging materials where gas
barrier
performance minimizes the oxidation reaction, leading to
improved food or juice freshness and longer shelf life.
Bottles
MX-Nylon is utilized in PET bottle applications worldwide
in both multilayer and blend structures. MX-Nylon
improves
the gas barrier performance of PET in bottles and because
it has very many similar physical and thermal properties
to PET, is easy to process and recycle. Current successful
applications include multilayer and blend combinations
commercially used worldwide for tea, juice, carbonated
soft drinks and beer. |

 |
Films
MX-Nylon has been utilized for biaxially oriented film
applications, both multilayer and blends in combination
with Nylon-6 and/or PET for improving gas barrier properties.
It has also been used in multilayer films in combination
with olefinic resins such as polyethylene, polypropylene
for not only improving gas barrier properties but
also
in retorting applications where EVOH has limitations. |
Sheets
MX-Nylon superior gas barrier properties makes it the
best material for multilayer sheet applications used
in
thermoform containers, where special retorting and sterilization
needs must be met. |
Laminated
Paperboards
Recently MX-Nylon has demonstrated its unique properties
in combination with laminated paperboard applications.
MX-Nylon has the benefit of good gas barrier properties,
but it is also easy to laminate at high process temperatures
and production speeds. Recent laminated paper board applications
include containers of tea, vegetable juice and soy milk.
