Description :
PA6T, also known as poly (p-phenylene terephthalamide), is a heat-resistant nylon 6T/66 developed by Mitsui Chemicals, Inc. in Japan. It is a copolymer of PA6TPA6T and PA66. Foreign name: nylon6T Welcome Wholesale Welcome to inquire! Super rigid PA6T Japanese Mitsui AE2230 circuit breaker super engineering material
The reasons and solutions for the occurrence of sinks during the processing of PA6T are as follows:
High molding temperature - reduce molding temperature
Mold temperature high/low - make the mold temperature appropriate
Low injection holding pressure - Increase injection holding pressure
Keep the time short - increase the insulation time
Short cooling time - Extended cooling time
No cushion - take a cushion of about 5 millimeters
Meanwhile, PA6T is a low water absorption polyamide, but if left in the air for a long time, it will absorb water like other polyamides. Forming in a water absorbing state leads to foaming, dripping, poor appearance, and decreased mechanical properties. After using PA6T, do not leave it in the air for a long time and store it with the outside air closed.
Mitsui Chemicals has achieved high heat resistance by incorporating aromatic rings into its basic framework, with a melting point of 320 ° C, and has also solved the problem of water absorption, which is a weakness of conventional polyamide resins. By adding a third component and modifying it, it has a polymer structure that balances heat resistance and low water absorption while maintaining good formability. It is also a surface mount lead-free solder that has supported IT technology in recent years. It is an excellent polyamide resin that can withstand more. Aalen is a confident work by Mitsui Kagaku, which is the world's large-scale production of modified polyamide 6T.
Characteristics of Mitsui PA6T:
High heat resistance:The Aalen E series maintains a high melting point of 320 ° C and has good flowability during the molding process.
Low water absorption rate:The reason for the high water absorption rate of polyamide is that water molecules are hydrogen bonded to the amide group in the molecular structure. By reducing the concentration of amide groups that cause water absorption, Aalen's water absorption is one-third lower than PA46.
High mechanical strength:Due to the rigid aromatic rings and low water absorption in the molecular chain, Aalen has achieved excellent mechanical strength.
Bending elasticity (at room temperature, dry state):E series (E440N)=14600MPa, A-series (A350)=17000MPaIt has excellent liquidity.
Chemical resistance:It has the ultimate chemical resistance among all polyamides.
High temperature rigidity:Due to the high glass transition temperature (125 ° C), high rigidity can be maintained even in high-temperature environments, such as in the cabin.
PA6T Application: Compatible with SMT electronic parts such as connectors, sockets and switches, automotive parts, automotive electrical parts, cylinder head covers, thermal protection boxes and other cabin parts
