Key Characteristics of PA MXD6 CF30

1. High Mechanical Strength：The addition of 30% carbon fiber significantly enhances the tensile and flexural strength of the material, making it suitable for high-load applications.
2. Excellent Heat Resistance：PA MXD6 CF30 has a high glass-transition temperature and maintains its properties at elevated temperatures, ensuring stable performance in hot environments.
3. Low Water Absorption：Compared to other nylons, PA MXD6 CF30 has low water absorption, which minimizes dimensional changes and maintains mechanical strength in humid conditions.
4. High Stiffness：The material exhibits high rigidity, making it ideal for applications requiring precise dimensional stability and resistance to deformation.
5. Superior Gas Barrier：PA MXD6 CF30 offers excellent barrier properties against gases like oxygen and carbon dioxide, making it suitable for packaging applications.
6. Good Chemical Resistance：It has good resistance to various chemicals, including oils and solvents, which is beneficial for applications in harsh chemical environments.

Optimal process parameters for PA MXD6 CF30 composite materials

Injection Molding Process Parameters
– Temperature: The barrel temperature is usually set between 280 °C and 320 °C, and the nozzle temperature is slightly lower, approximately between 270 °C and 300 °C. This ensures that the material is fully melted and has good fluidity for filling the mold cavity easily. The mold temperature is recommended to be controlled within 80 °C – 120 °C, which helps in cooling and shaping the product, reducing internal stress and improving the appearance quality and dimensional accuracy of the product.
– Pressure: The injection pressure generally ranges from 80 MPa to 150 MPa depending on the complexity and size of the product. The holding pressure can be set at 50% – 80% of the injection pressure to ensure uniform density of the product and prevent defects such as sink marks.
– Speed: The injection speed should not be too fast, and a medium to low speed is preferred to avoid problems like air traps and jetting marks. It is usually controlled at 30 – 60 mm/s. The screw rotation speed can be set at 50 – 100 rpm to ensure uniform plasticization of the material.

Extrusion Moulding Process Parameters
– Temperature: From the feeding section to the die, the temperature increases gradually. The feeding section is set at 250 °C – 270 °C, the plasticizing section at 280 °C – 310 °C, the homogenizing section at 300 °C – 320 °C, and the die temperature at around 300 °C to ensure the stable extrusion of the material.
– Screw Rotation Speed: Depending on the specifications of the extruder and the production requirements, it is usually set at 30 – 60 rpm to ensure the uniform mixing of the material and its smooth extrusion to obtain extruded products of qualified quality.
