Application field

MXD6 application in plastic modification industry

 

MXD6 can be compounded with glass fibers, carbon fibers, minerals and (or) advanced fillers, MXD6 can be used to contain 50-60% glass fiber reinforced materials, and has extraordinary strength and stiffness. What sets this material apart is that its smooth, resin-rich surface yields a glass-free high-gloss finish even when filled with high glass fibres, making it ideal for painting, metallizing or creating natural Reflective shell.

 

Advantage:
1. High fluidity for thin wall
Is a very high flow resin that can easily fill thin walls as low as 0.5 mm even at glass fiber contents as high as 60%.
2. Excellent surface finish
The perfect resin-rich surface has a high-gloss finish, even with a high glass fiber content.
3. High strength and rigidity
MXD6 adds 50-60% glass fiber reinforcement, and its tensile strength and flexural strength are similar to many cast metals and alloys.

4. Good dimensional stability
At ambient temperature, the coefficient of linear expansion (CLTE) of MXD6 glass fiber composites is close to that of many cast metals and alloys. High reproducibility due to low shrinkage and ability to hold tight tolerances (length tolerances can be as low as ± 0.05% if properly formed).

 

 

 

 

Application of MXD6 in the field of barrier

 

PET/MXD6 multilayer bottle

 

PET resin and MXD6 are used for injection molding, and the bottle formed by extension blow molding is a multi-layer bottle.
Its structure is PET/MXD6/PET.
The multi-layer bottle has high transparency and excellent gas barrier performance, which can effectively block the infiltration of oxygen and the loss of carbon dioxide, and can meet the needs of products with high barrier performance, such as high-concentration fruit juice, tea, beer, carbonated beverages and functional beverages .

 

 

PET/MXD6 single mixed bottle

The bottle made by blending PET and MXD6 is a single-mix bottle. The single-mix bottle forming process is simple, and it can be produced by conventional machines without delamination, peeling and other problems.
The single-mix bottle has excellent gas barrier performance, but its appearance is not completely transparent, with a layer of haze similar to pearl-colored mist. The shelf life of the single mixed bottle with 5% MX nylon is twice that of ordinary PET bottles.

 

Film

NYLON-MXD6 is suitable for the production of multilayer and blended films. Due to its excellent barrier properties under high humidity conditions, good processability and superior thermal stability, MXD6 is the best choice for barrier materials of nylon 6 multilayer film, nylon 6 blend film and PET blend film.
Adding a certain amount of MXD6 can effectively improve the gas barrier properties of the film, whether it is a multilayer film or a monomixed film.
