Nylon66 PA66 Heat Stabilized a high temperature nylon made by the polycondensation of terephthalic acid and hexamethylene diamine. Heat stabilized nylon 6 has the properties of low water absorption, excellent heat resistance, good processing fluidity, low expansion coefficient, and high bonding strength with metals.
The advantages of Anmei heat-resistant nylon are as follows, and it meets the new requirements of new energy vehicles for plastics:
- Comply with relevant regulatory requirements(DPPD-free, no anti-Oxidant Aromatic Amine type additive)
- Long-term heat-resistant stability(Long-term resistance to high temperatures of 190 ° C and 230 ° C, and with high strength)
- Low extractables(Do not block the oil circuit of the capillary structure)
- Electrially Neutral(Do not cause short circuit of the circuit)
- Low warpage
PA6 has good toughness and is used in climbing hands, automotive structural parts, etc. PA66 has both toughness and hardness, and is used in industrial gears such as marine propellers.
