ARLEN™ is a heat resistant, modified polyamide 6T developed by Mitsui Chemicals, Inc. With a high melting point (320°C) and a rigidity level comparable to super engineering plastics, it possesses strong dimensional stability and chemical resistance. In addition, the effect of water absorption, which is a traditional weakness of polyamides, has been reduced to a minimum.
There are three individual offerings in the modified polyamide product series; each polyamide designed to meet a specific application requirement as presented below:
| A/G Series | Mechanical and structural parts |
| AE Series | For tribological applications |
| C Series | Electrical and electronic parts |
Electrical and Electronic: For a graphical presentation of ARLEN's electrical and electronic characteristics, please click on the chart below:
Mechanical and Structural:
- High temperature rigidity - Due to its high glass transition point (125°C), ARLEN can retain high rigidity even in a high-temperature atmosphere, such as the inside of an engine room.
- Heat Resistant
- Dimensional Stability
- Chemical Resistance - demonstrating the best chemical resistance of all polyamide resins.
- Little dimensional change due to water absorption - The dimensional change of ARLEN due to water absorption is less than 1/2 of PA66, which is the lowest of all polyamide resins.
In electrical and electronic parts, this modified polyamide can be used in:
- Connectors
- Jacks
- Switches
- Power supply terminals
- Various cases
Automotive Applications - Engineering Plastic for Under the Hood Applications
The heat resistant modified polyamide 6T A/G and AE series are designed to meet specific mechanical, structural and tribological application requirements of under the hood parts including:
- Cooling system parts
- Cylinder head covers
- Thermostat cases
- Hydraulic system pistons
- Oil pump housings
Other mechanical and structural applications include light-load tribological application parts of office automation equipment.
Mitsui Chemicals recommends the following to mold this sophisticated engineering plastic for any application part:
Molding machine:
- The injection molding of this modified polyamide requires a molding machine having wear resistance (corrosion resistance for the flame-retardant grade).
- A small molding machine should be selected so that the volume of one shot will be not less than 10% of the maximum injection capacity.
- A standard nozzle should be used.
Mold:
- A steel material having wear resistance (corrosion resistance for the flame-retardant grade) is required for the construction material of a mold for ARLEN.
- An approximately 10-µ m vent is required.
Predrying:
- Any ARLEN resin that absorbs moisture after the bag is opened needs to be dried again.
- Dehumidifying dryer: 110°C x 2 to 6 hr.
