Feature editing
PA66 plastics have a higher melting point in polyamide materials. PA66 plastic is still hygroscopic after molding, PA66 plastic has low viscosity, PA66 plastic thermal melting point is the temperature at which crystal is melted, and crystalline polymer PA66 plastic shows clear melting point. According to the test method used, the melting point is Fluctuations in the range of 259~267 °C. The melting point of PA66 plastics, usually measured by differential thermal analysis, is 264 °C. If the temperature at which the volume expansion coefficient shows the maximum value is taken as the melting point, the melting point temperature of the nylon-66 is in the range of 246 to 263 °C. Close to the theoretical melting temperature of 259 ° C. Drying treatment of injection molding properties of PA66 plastic: 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%, it is also necessary to carry out vacuum drying at 105 C for 12 hours.
Melting temperature: 260~290C. The product for glass additives is 275~280C. The melting temperature should be avoided above 300C.
Mold temperature: 80C is recommended. The mold temperature will affect the crystallinity, which will affect the physical properties of the product. for
Thin-walled plastic parts, if a mold temperature lower than 40C is used, the crystallinity of the plastic part will change with time, in order to maintain
The geometric stability of the plastic part requires annealing.
Injection pressure: usually between 750 and 1250 bar, depending on material and product design.
Injection speed: high speed (slightly lower for reinforced materials).
Runners and gates: Because of the short settling time of the PA66, the location of the gate is very important. The gate aperture should not be less than 0.5*t (where t is the thickness of the plastic part). If a hot runner is used, the gate size should be smaller than with a conventional runner because the hot runner can help prevent premature solidification of the material. If a submerged gate is used, the minimum diameter of the gate should be 0.75 mm. PA66 plastic application PA66 is the most mechanically strong and widely used variety in the PA series. Because of its high crystallinity, it has high rigidity and heat resistance.

  Variety
Including aliphatic polyamides, fat-aromatic polyamides and aromatic polyamides. Aliphatic polyamides have many varieties, large yields and wide applications, and can be used as both fibers and plastics. Polyamide fiber is also called nylon, and its yield ratio to polyamide plastic is 9:1. There are few varieties of fat-aromatic polyamides and the yield is small. Aromatic polyamides are often referred to as polyaramids, mainly as fibers, and the latter are called aramid fibers, commonly known as aramid. The name of the polyamide variety is industrially accustomed to the number of carbon atoms contained in the unit chain link, and can be roughly classified into p-type and mp-type according to the polymer monomer. The p-type polyamide is made of the amino acid H2N(CH2)p-1COOH (or lactam). The unit link structure is: [-HN(CH2)p-1-CO-], such as polyamide 6[-HN(CH2)5CO-]n; polyamide 11[-HN(CH2)10CO-]n and the like. Their names 6 and 11 represent the number of carbon atoms in the unit link, respectively. The mp type polyamide is made of the dibasic acid HOOC-(C-H2)m-2COOH and the diamine H2N(CH2)pNH2, and the unit link structure is: [—OC—(CH2)m-2CONH(CH2) pNH—], such as polyamide 66 [-OC(C-H2)4CONH(CH2)6NH-]n, polyamide 1010[-OC(CH2)8CONH(C-H2)10-NH-]n, and the like. Their names 66 and 1010 represent the number of carbon atoms of the acid and amine in the unit chain, respectively. The main varieties of polyamide plastics produced industrially are polyamide 66, polyamide 6, polyamide 610, polyamide 1010, polyamide 11, polyamide 12 and copolyamide. According to the additives added in the polyamide, the polyamide has different modified varieties such as reinforcement, wear resistance, microcrystal and anti-aging; according to the processing and molding method, it can be divided into injection molding, extrusion, molding, casting, sintering, etc. Variety; according to its form can also be divided into pellets, films, powders and blanks.

Performance editing

PA66 plastic material is a translucent or opaque milky white crystalline polymer with plasticity. The density is 1.15 g/cm3. The temperature of 252 ° C. The embrittlement temperature is -30 °C. The thermal decomposition temperature is greater than 350 °C. Continuous heat resistance 80-120 ° C, equilibrium water absorption rate of 2.5%. It can resist acid, alkali, most inorganic salt aqueous solutions, halogenated alkane, hydrocarbons, esters, ketones, etc., but is easy to contain polar solvents such as phenol and formic acid. It has excellent wear resistance, self-lubricating properties and high mechanical strength. However, the water absorption is large, so the dimensional stability is poor.
PA66 is the most mechanically strong and widely used variety in the PA series. Because of its high crystallinity, PA66 has high rigidity and heat resistance.

Feature editing
PA66 has a higher melting point in polyamide materials. It is a semi-crystalline-crystalline material. PA66 also maintains high strength and stiffness at higher temperatures. PA66 is still hygroscopic after molding, the extent of which depends primarily on the composition of the material, the wall thickness and the environmental conditions. When designing a product, it is important to consider the effect of hygroscopicity on geometric stability.
In order to improve the mechanical properties of PA66, various modifiers are often added. Glass is the most common additive, and sometimes synthetic rubbers such as EPDM and SBR are added to improve impact resistance.
PA66 plastic picture
PA66 is less viscous and therefore has good fluidity (but not as good as PA6). This property can be used to machine very thin components. Its viscosity is sensitive to temperature changes. The shrinkage of PA66 is between 1% and 2%. The addition of glass fiber additives can reduce the shrinkage to 0.2%~1%. The shrinkage ratio is large in the flow direction and in the direction perpendicular to the flow direction.

Feed zone and zone 1 temperature directly affect feed efficiency, increasing these temperatures can make feed more even
PA66 plastic raw material melt temperature: 270 ~ 290 °C barrel constant temperature: 240 ° C mold temperature 60 ~ 100 ° C
Injection pressure: 100 ~ 160MPa (1000 ~ 1600bar), if you are processing thin section long channel products (such as wire tie), you need to reach 180MPa (1800bar)
PA66 plastic raw material holding pressure: 50% of the injection pressure; due to the relatively fast material condensation, a short holding time is sufficient. Reduce the pressure of the pressure to reduce the stress inside the product
Back pressure: 2~8MPa (20~80bar), need to be accurately adjusted, because the back pressure is too high, it will cause the plasticizing uneven injection speed. It is recommended to use a relatively fast injection speed; the mold has good ventilation or the product is prone to coking. phenomenon
Screw speed High screw speed, line speed is 1m / s; however, it is best to set the screw speed to a lower point, as long as the plasticizing process can be completed before the end of the cooling time; the required screw torque is low
Measuring stroke (0.5~3.5)D
Residual material amount 2~6mm depends on metering stroke and screw diameter
Pre-baking Drying at 80 °C for 4 h, except directly feeding from the charging container; nylon is water-absorbent and should be stored in a moisture-proof container and a closed hopper; a water content of more than 0.25% will cause a molding change.
Recovery rate can be added to 10% return material
PA66 plastic raw material shrinkage: 0.7% ~ 2.0%, or added 30% of glass fiber, 0.4% ~ 0.7%; if the temperature provided exceeds 60 ° C, the product should be gradually cooled; gradually cooling can reduce shrinkage after molding, That is, the product exhibits better dimensional stability and small internal stress; steam method is recommended; nylon products can be inspected by melt flux
Gate system point type, latent type, chip type and sprue can be used; blind hole and gate socket are recommended to break the cooling head; hot runner can be used; hot runner should be provided due to the narrow processing temperature range of the melt Closed loop temperature control
Machine downtime No need to clean with other materials; the melt remains in the barrel for up to 20 minutes, after which thermal degradation is easy to occur
