- Product description
- Specific applications
-
PA46 (Polyamide 46) is a new type of polyamide resin with a high melting point and high crystallinity. DSM (Royal Dutch Company) was one of the first in the world to successfully establish a method for industrial production of PA46, marketed under the name Stanyl, and has promoted it globally as a leading brand of heat-resistant and wear-resistant polyamide 46.
Molecular structure of PA46
PA46 is an aliphatic polyamide formed by the polycondensation of hexamethylenediamine and adipic acid. Although it has a molecular structure similar to nylon 66, Stanyl PA46 has more amide groups on each given length of the chain, and the chain structure is more symmetrical; this highly symmetrical chain structure results in a high degree of crystallinity (about 70%) and a fast crystallization rate, leading to a higher melting point (295°C) and a high heat distortion temperature, with a long-term use temperature (CUT 5000 hours) reaching 163°C. These characteristics give Stanyl PA46 a technical advantage over other engineering plastics such as PA6, PA66, PPA, and polyester in terms of heat resistance, mechanical strength at high temperatures, wear resistance, and also allow for shorter molding cycles and more economical processing.
Stanyl high-performance polyamide 46 has unparalleled performance and value in automotive and electronic applications, providing excellent mechanical properties, outstanding wear resistance, low friction, and excellent flowability under high-temperature conditions, making processing more convenient and special designs more flexible. Stanyl's performance surpasses that of PPA, PA6T, and PA9T, and it typically outperforms PPS and LCP materials under high-temperature working conditions.
Processing performance
A: It has easy processability and excellent flow properties.B: It has excellent tensile strength and good thermal insulation properties.
C: Flame retardant, electroplatable, thermally stabilized, and heat-resistant.
D: High rigidity retention performance, while exhibiting good high-temperature creep resistance.
E: Rigidity and creep modulus are comparable to PPS, PEI, and PES with the same level of glass reinforcement.
F: It can be used for thin-walled parts reaching 0.1 mm without flash.
G: PA46 plastic is a versatile, glass-reinforced, flame-retardant UL grade material that complies with UL VO regulations.
