In the field of engineering plastics, PA66 (polyamide 66, also known as nylon 66) has become an industry benchmark with its excellent comprehensive performance. As a translucent or opaque milky white crystalline polymer, PA66 is widely used in the automotive, electronics, machinery manufacturing and consumer goods industries due to its excellent mechanical strength, wear resistance and chemical corrosion resistance. It is the star material with the highest output among the five major engineering plastics.
Core performance advantages
Excellent temperature resistance
PA66 has a melting point of up to 252°C, a continuous heat resistance temperature range of 80-120°C, a thermal decomposition temperature of more than 350°C, and a low-temperature brittle point of -30°C, which can adapt to harsh high and low temperature working environments.
Excellent mechanical properties
The material has high mechanical strength and rigidity, as well as outstanding wear resistance and self-lubricating properties. It is particularly suitable for parts such as gears, bearings, and guide rails that need to withstand friction for a long time.
Stable chemical resistance
Resistant to acids, alkalis, inorganic salt solutions and most organic solvents (such as halogenated alkanes and hydrocarbons), but sensitive to polar solvents such as phenol and formic acid, which need to be avoided.
Balanced water absorption
The 2.5% balanced water absorption rate provides good processability, but it is necessary to optimize dimensional stability through post-processing or modification.
Diversified product matrix
Relying on 15 years of professional R&D and production experience, we have launched a variety of PA66 grades to accurately match the needs of different application scenarios:
General grade: 6630H (high fluidity), 6600F (standard injection molding)
Reinforced grade: 6615F (15% glass fiber reinforcement), 6620F (20% glass fiber reinforcement), 6630F (30% glass fiber reinforcement) – significantly improve rigidity and dimensional stability
Special grades: 6600Z (impact modified), 6600S (special for low warpage)
Each product is strictly quality controlled to ensure reliable performance from automotive engine parts to electronic connectors, from industrial gears to daily tools.
