PA6 Established ET6000-5016 LD Black 70 PolyOne Corporation Nylon 612

Item No.: ET6000-5016 LD
PA6, also known as nylon 6, is a translucent or opaque milky white granule. It is thermoplastic, lightweight, tough, chemical and durable. It is commonly used in automotive parts, mechanical parts, electronic parts

       Melting point: 210 - 220 °C De
Content: The chemical and physical properties of PA6 are similar to those of PA66. However, it has a low melting point and a wide process temperature range. It has better impact resistance and
 Solubility is better than PA66, but it is also more hygroscopic. Because many of the quality characteristics of plastic parts are affected by hygroscopicity
 This should be taken into account when designing products with PA6. In order to improve the mechanical properties of PA6, various modifiers are usually added. Fiberglass is the most common
 Additives, sometimes adding synthetic rubbers such as EPDM and SBR to improve impact resistance. For products without additives, PA6 will shrink
 Between 1% and 1.5%. The addition of a glass fiber additive reduces the shrinkage to 0.3% (but slightly higher in the direction perpendicular to the flow).
 The shrinkage of the molded component is primarily affected by the crystallinity and hygroscopicity of the material. Actual contraction is also a
 Process parameters such as plastic part design functions, wall thickness, etc.

PA6 is widely used in automobiles. Automobiles are an important and fast-growing market for plastics. PA6 has good comprehensive performance, low density, easy molding, large design freedom, thermal insulation, and obvious advantages in mold and assembly costs. . PA6 not only has high tensile strength, excellent impact performance, high heat distortion temperature, heat resistance, low friction coefficient, excellent wear resistance, self-lubrication, oil resistance and chemical resistance, and is especially suitable for filling with glass fiber or other materials. Modification, improving material properties and grades to meet the final components and customer needs. At present, there are many kinds of PA6 automobile products, such as radiator box, front grille, heater box, radiator blade, steering column cover, tail light cover, adsorption tank, timing gear cover, fan blade, various gears, radiator water chamber, Air filter housing, intake manifold, control switch, intake duct, vacuum connection tube, airbag, electrical instrument housing, wiper, pump impeller, bearing, bushing, valve seat, door handle, wheel cover, etc. In short, it involves many parts such as automobile engine parts, electrical parts, body parts and airbags. Among them, the amount of parts under the hood of the automobile is the largest, which is due to the miniaturization and light weight development of the automobile, the volume of the engine room is reduced, the temperature is increased, and the parts under the hood are required to be more resistant to high temperatures, and the PA6 can be fully modified by the above modification. Claim. Some industrial analysts believe that PA6 components not only have a protective effect, but also have an aesthetic effect.

PA6 plastic raw material process conditions melt temperature? 240-250 °C barrel constant temperature? 220 °C PA6 mold temperature? 60-100 °C drying treatment? Because PA6 is easy to absorb moisture? Therefore, special attention should be paid to the drying before processing? If the material is used If the waterproof material is supplied in a package, the container should be kept closed. If the humidity is greater than 0.2%, it is recommended to dry in hot air above 80 °C for 16 hours. If the material has been exposed to air for more than 8 hours, it is recommended to perform vacuum drying at a temperature of 105 ° C for more than 8 hours. Melting temperature? 230-280 ° C? For enhanced varieties 250-280 ° C. Mold temperature? 80-90 ° C. The mold temperature significantly affects the crystallinity, which in turn affects the mechanical properties of the part. Crystallinity is important for structural components? It is therefore recommended that the mold temperature be 80-90 °C. It is also recommended to apply a higher mold temperature for thin-walled, longer-flowing plastic parts. Increasing the mold temperature increases the strength and stiffness of the part, but reduces the toughness. If the wall thickness is greater than 3mm, a low temperature mold of 20-40 °C is recommended. For glass fiber reinforced materials, the mold temperature should be greater than 80 °C. Injection pressure? Generally between 750-1250bar? Depends on material and product design? Injection speed? High speed? Reduces the reinforcement material slightly? Flow path and gate? The solidification time for PA6 is very short? Therefore, the position 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. Injection pressure? 100-160MPa? 1000-1600bar?? If it is processing thin surface long runner products, such as wire tie, it needs to reach 180MPa? 180bar?. Holding pressure? 50% of injection pressure? Because material condensing is relatively fast? Short holding time is sufficient. Reducing the holding pressure reduces 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 uneven plasticization.
