PA66 的粘较低，因此流动很好（但不如 PA6）。这个质可以用来加工很薄的元件。 它的粘度对温度变化很敏感。PA66 的收缩率在 1%~2%之间，加入玻璃纤维添加剂可以将收缩率降低到 0.2%~1% 。收缩率在流程方向和与流程方向相垂直方向上的相异是较大的。
PA66 has low viscosity, so it has good fluidity (but not as good as PA6). This property can be used to process very thin components. Its viscosity is sensitive to temperature changes. The shrinkage of PA66 is in the range of 1% ~ 2%, and it can be reduced to 0.2% ~ 1% by adding gss fiber additive. The difference of shrinkage rate in the process dirion and in the dirion perpendicur to the process dirion is rger.
Basic physical properties of PA66: PA66 is still the most important variety. The melting point, tensile strength, bending strength and hardness of PA66 are the highest in the nylon fily, so it is widely used in various fields. It can also maintain strong strength and stiffness at higher temperature. The melting point of PA66 is 260 ℃; it is a semi crystalline crystalline material. PA66 is resistant to many soents, but weak to acids and other Chlorinators. The shrinkage of PA66 is between 1% and 2%, which can be reduced to 0.2% - 1% by adding gss fiber additive. PA66 has low viscosity, so it has good fluidity. This property can be used to process very thin components. Its viscosity is sensitive to temperature changes. It still has hygroscopicity after molding, and its degree mainly depends on the comition of the material, wall thickness and environmental conditions. The influence of Hygroscopicity on geometric stability must be considered in product design.
PA66 process: drying: if the material is sealed before processing, there is no need to dry. However, if the storage container is opened, drying in hot air at 85 ℃ is recoended. If the humidity is higher than 0.2%, vacuum drying at 105 ℃ for 12 hours is required. Melting temperature: 260 ~ 290 ℃. For gss additive products, 275 ~ 280 ℃. The melting temperature should not be higher than 300 ℃.
The development of PA66: in the te 1940s, Dopont company in the United States realized the industrial production of PA66. At present, there are more than 20 kinds of nylon resins in the world aording to their structures, with more than 800 brand numbers. The product ne is determined by the number of carbon atoms in the repeating unit of nylon macromolecule. The general formu can be written as nylon or Pa. There are PA6, PA66, PA11, PA12, PA610, pa612, PA1010, PA46, PA6T, PA9T, etc. ong them, PA6 and PA66 are the main varieties, aounting for about 92% of the total ount of PA engineering pstics.
Application fields of PA66:
1. It is widely used in machinery, instrumentation, automobile parts, elronic and elrical, railway, household appliances, counication, textile machinery, sports leisure goods, oil pipe, oil tank and some precision engineering products.
2. Elrical and elronic equipment: connor, reel, timer, cover circuit breaker, switch housing base
Automobile: radiator n, door handle, fuel tank cover, air intake grille, water tank cover, lp holder
3. Industrial parts: chair seat, bicycle fre, skate base, textile shuttle, pedal, slide conveyor
