Various Grades and Uses
It is easy to combine Nylon-MXD6 with other materials for co-extrusion and co-injection molding. This property makes possible its wide-range of applications, e.g., the production of laminated films, sheets and containers.
You can also blend Nylon-MXD6 with other materials to improve mechanical properties and to achieve greater gas-barrier characteristics.
In addition, the excellent physical properties of Nylon-MXD6, e.g., great strength, high elastic modulus, and low water absorption, are enhanced when Nylon-MXD6 is used as a molding material in the production of monofilaments and special fibers.
Uses

Grades
Nylon-MXD6 is available in three different grades of varying molecular weight. Table 6 shows the various grades and their properties.
| Property | Grades | ||
|---|---|---|---|
| S6001 | S6007 | S6121 | |
| Relative Viscosity | 2.2 | 2.7 | 3.5 | 
| MI | 7 | 2 | 0.5 | 
| Moisture Content (%) | 0.1 or less | 0.1 or less | 0.1 or less | 
| Melting Point (℃) | 240±5 | 240±5 | 240±5 | 
Table 7 shows examples of grade selection to match the desired use. As the Table shows, Nylon-MXD6 can be used for various applications to produce films, sheets, bottles, trays and cups.
| Applications | Grades | 
|---|---|
| Monolayer or Multilayer films | S6007 | 
| Multilayer sheets | S6007, S6121 | 
| Multilayer bottles and tubes (extrusion blow) | S6007, S6121 | 
| Monolayer blend bottles with PET (injection stretch blow) | S6007 | 
| Multilayer bottles with PET or PP (co-injection stretch blow) | S6007 | 
| Monofilaments | S6007 | 
| Injection moldings | #6000 |
