characteristic
1. It has excellent wear resistance, self lubrication and high mechanical strength. But the water absorption is large, so the dimensional stability is poor
2. PA66 can also maintain strong strength and stiffness at higher temperatures. PA66 still has hygroscopicity after molding, and its degree mainly depends on material composition, wall thickness and environmental conditions.
3. In product design, the influence of moisture absorption on geometric stability must be considered. In order to improve the mechanical properties of PA66, various modifiers are often added. Glass is a common additive. Sometimes synthetic rubber, such as EPDM and SBR, is added to improve impact resistance. The viscosity of PA66 is low, so its liquidity is very good (but not as good as PA6). This property can be used to process very thin components. Its viscosity is very sensitive to temperature changes.
4. The shrinkage of PA66 is between 1% and 2%, and the addition of glass fiber additive can reduce the shrinkage to 0.2%~1%. The shrinkage rate differs greatly in the flow direction and the direction perpendicular to the flow direction. PA66 is resistant to many solvents, but weak to acids and other chlorinating agents.

1、 Type of PA66
It includes aliphatic polyamide, fat aromatic polyamide and aromatic polyamide.
Aliphatic polyamides have many varieties, PA66 products and wide applications, which can be used as both fiber and plastic. Polyamide fiber, also known as nylon, has a 9 ∶ 1 ratio of varieties and uses to polyamide plastic PA66. Fat aromatic polyamide has few varieties, and the varieties and uses of PA66 are also small.
Variety and use of PA66
Aromatic polyamide is often referred to as polyaromamide, which is mainly used as fiber. The latter is called aromatic polyamide fiber, commonly known as aramid. The name of polyamide variety is traditionally characterized by the number of carbon atoms contained in the chain link of the single PA66 variety and purpose in industry. It can be generally divided into p type and mp type according to the polymer monomer. P-type polyamide is made of amino acid H2N (CH2) p-1COOH (or lactam). The variety and use of single PA66 The chain link structure is: [- HN (CH2) p-1CO -], such as polyamide 6 [- HN (CH2) 5CO -] n; Polyamide 11 [- HN (CH2) 10CO -] n, etc. 6 and 11 in their names respectively represent the number of carbon atoms in the variety and use chain link of single PA66. The mp type polyamide is made from the variety and use of the two PA66 acid HOOC - (CH2) m-2COOH and the variety and use of the two PA66 amine H2N (CH2) pNH2. The variety and use chain structure of the single PA66 is: [- OC - (CH2) m-2CONH (CH2) pNH -], such as polyamide 66 [- OC (CH2) 4CONH (CH2) 6NH -] n, polyamide 1010 [- OC (CH2) 8CONH (CH2) 10-NH -] n, etc. 66 and 1010 in their names respectively represent the number of carbon atoms of acid and amine in the chain link of the variety and use of single PA66. The main varieties of polyamide plastics produced in industry include polyamide 66, polyamide 6, polyamide 610, polyamide 1010, polyamide 11, polyamide 12 and copolyamide. According to the different additives added in polyamide, polyamide has different varieties of PA66 and different modified varieties such as strong use, abrasion resistance, microcrystalline, anti-aging, etc; According to the processing method, it can be divided into injection molding, extrusion, molding, casting, sintering and other varieties; According to its shape, it can also be divided into granules, films, powders and billets.
2、 Use of PA66
Polyamide plastic products are widely used as various mechanical and electrical parts, including bearings, gears, pulley pump impellers, blades, high-pressure sealing rings, gaskets, valve seats, bushings, oil pipes, oil reservoirs, ropes, transmission belts, grinding wheel adhesives, battery boxes, electrical coils, cable connectors, etc. There are also quite a lot of varieties and uses of PA66 produced by packaging tape and food film (high-temperature film for cooked food and low-temperature film for cool drinks)
PA66 plastic has a high melting point in polyamide materials. It is a semi crystalline crystalline material. PA66 can also maintain strong strength and stiffness at higher temperatures. PA66 plastic still has hygroscopicity after molding, and its degree mainly depends on material composition, wall thickness and environmental conditions. In product design, the influence of moisture absorption on geometric stability must be considered. In order to improve the mechanical properties of PA66, various modifiers are often added. Glass is a common additive, and sometimes synthetic rubber is added to improve impact resistance. PA66 plastic has low viscosity, so its fluidity is very good (but not as good as PA6). This property can be used to process very thin components. Its viscosity is very sensitive to temperature changes. The shrinkage of PA66 is between 1% and 2%, and the addition of glass fiber additive can reduce the shrinkage to 0.2%~1%. The shrinkage rate differs greatly in the flow direction and the direction perpendicular to the flow direction. The melting point of the thermal properties of PA66 plastic is the temperature of crystallization melting. For crystalline polymer PA66 plastic, the melting point is clearly displayed. According to the test method used, the melting point fluctuates between 259 ℃ and 267 ℃. Generally, the melting point of PA66 plastic measured by differential thermal analysis is 264 ℃. If the temperature of the displayed volume expansion coefficient is taken as the melting point, the melting point temperature range of nylon - 66 is 246~263 ℃. It is close to the theoretical melting temperature of 259 ℃. Injection molding characteristics of PA66 plastic Drying treatment: if the material is sealed before processing, there is no need to dry. However, if the storage container is opened, it is recommended to dry it in hot air at 85C. If the humidity is greater than 0.2%, vacuum drying at 105C for 12 hours is also required.
Melting temperature: 260~290C. The product of glass additive is 275~280C. The melting temperature should avoid 300C.
Mold temperature: 80C is recommended. The mold temperature will affect the crystallinity, which will affect the physical properties of the product. about
For thin-walled plastic parts, if the mold temperature is lower than 40C, the crystallinity of the plastic parts will change with time
The geometric stability of plastic parts requires annealing treatment.
Injection pressure: usually 750~1250bar, depending on the material and product design.
