Nylon is a term for polyamide fiber (nylon), which can be made into long fiber or short fiber. Nylon is the trade name of polyamide fiber, also known as Nylon. The English name Polyamide (PA for short), its basic composition is an aliphatic polyamide connected by an amide bond—[NHCO]—. Depending on the number of carbon atoms contained in diamines and diacids or amino acids, a variety of different polyamides can be prepared, with dozens of varieties of polyamides, among which PA66 and PA6 are the most widely used. Then we will have an in-depth understanding of those things about PA66 and PA6 today! PA6     Nylon 6, also called PA6, polyamide 6. It is an organic substance with the chemical formula C6H11NO. PA6 is a PA6 polymer synthesized by German IG company Schrak using a single caprolactam as the raw material ε-aminocaproic acid as the initiator to heat and synthesize it. In 1939, the experimental production of PA6 fiber was carried out, and in 1943, the German company Fabien completed the commercialization.   PA66    Nylon 66, nylon 66 resin, also called PA66, polyamide 66; polyhexamethylene adipamide. It is a semi-crystalline-crystalline material.    PA66 was polymerized into PA66 by Carothers successfully using adipic acid and hexamethylene diamine in 1935. From 1936 to 1937, the process of manufacturing PA66 by melt spinning was discovered, and it was commercialized by DuPont of the United States at the end of 1939.   The difference in performance PA6 product performance Melting point: 210-220 ℃ Decomposition temperature: >300℃ Flash point: >400 ℃ Auto-ignition temperature: >450 ℃ Physical state: solid particles Odor: None Toxicity: None Recycling: Yes Final treatment: soil (non-hazardous industrial waste) Fire extinguishing agent: can be transported with various fire extinguishing agents (water, foam, powder, CO2, sand): non-dangerous goods, suitable for various transportation vehicles European Community Standards: Non-dangerous goods   PA66 product performance Melting point: 250-270℃ Decomposition temperature: >350 ℃ Flash point: >400 ℃ Auto-ignition temperature: >450℃ Physical state: solid particles Odor: None Toxicity: None Recycling: Yes Final treatment: soil (non-hazardous industrial waste) Extinguishing agent: It can be transported with various extinguishing agents (water, foam, powder, CO2, sand): non-dangerous goods, applicable to various means of transport. European Community Standards: non-dangerous goods.     It can be seen that PA66 and PA6 are roughly the same, but in detail, PA66 has a higher melting point and a lower decomposition temperature. The difference in process conditions 1. Drying PA6   It is easy to absorb moisture, so special attention should be paid to drying before processing. If the material is supplied in waterproof packaging, the container should be kept tightly closed. If the humidity is greater than 0.2%, it is recommended to dry it in hot dry air above 80°C for 3 to 4 hours. If the material has been exposed to the air for more than 8 hours, it is recommended to perform vacuum drying at 105°C for more than 1 to 2 hours. It is best to use a desiccant dryer. PA66    If the material is sealed before processing, then there is no need to dry. If the storage container is opened, it is recommended to dry it in hot dry air at 85°C. If the humidity is greater than 0.2%, vacuum drying at 105°C for 1 to 2 hours is required. It is best to use a desiccant dryer. Molding temperature: 260~310℃, 280~320℃ for reinforced varieties.   2. Mold temperature PA6: 80~90℃ Mold temperature significantly affects crystallinity, which in turn affects the mechanical properties of plastic parts. For thin-walled plastic parts with longer processes, it is also recommended to use higher mold temperatures. Increasing the mold temperature can increase the strength and rigidity of the plastic part, but it reduces the toughness. If the wall thickness is greater than 3mm, it is recommended to use a low temperature mold of 20~40℃. For glass reinforced materials, the mold temperature should be greater than 80°C. PA66: 80℃ is recommended The mold temperature will affect the crystallinity, and the crystallinity will affect the physical properties of the product. For thin-walled plastic parts, if a mold temperature lower than 40°C is used, the crystallinity of the plastic parts will change with time. In order to maintain the geometric stability of the plastic parts, annealing treatment is required.   3. Melting temperature PA6: 230~280℃ For enhanced varieties, 250~280℃ PA66:260~290℃ For glass additive products, the temperature is 275~280℃. The melting temperature should not be higher than 300°C.    The difference in features and uses PA6 Features: fatigue strength steel, heat resistance lower than nylon 66, but good elasticity, has better vibration damping and noise reduction capabilities. It has high tensile strength, good impact resistance, excellent wear resistance, chemical resistance and low friction coefficient. Application: Light load, medium temperature (80-100), wear-resistant force transmission parts that work under conditions with no or little lubrication and low noise requirements. Mainly used in the automotive industry and electronic appliances.   PA66 Features: high fatigue strength and rigidity, good heat resistance, low friction coefficient, good wear resistance, good rigidity, impact resistance, oil and chemical resistance, wear resistance and self-lubricating advantages, especially hardness, rigidity, The heat resistance and creep performance are better, but the moisture absorption is large, and the dimensional stability is not enough. Application: Medium load, wear-resistant force transmission parts that work under the conditions of no lubrication or less lubrication at a temperature of <100-120 degrees. More used in the production of industrial yarns such as cords.
