Polyamide 12 PA12, nylon 12, also known as polydodecalactam and polylactam, is a long carbon chain nylon. There are non-polar methylene groups in nylon 12, and the number is large, which makes the flexibility of nylon 12 molecular chain larger; the amide group in nylon 12 is polar, and the cohesion energy is large, and it can form hydrogen bonds between molecules, which makes the arrangement of molecules more regular. Therefore, the crystallinity of nylon 12 is high, and the strength is also higher. Nylon 12 (PA12) has low water absorption, good low temperature resistance, good air tightness, excellent alkali resistance, grease performance, medium resistance to alcohols and inorganic dilute acids and aromatics, good mechanical properties and electrical properties, and is a self-extinguishing material. 1) Density The relative density of nylon 12 is only 1.01-1.03, which is the smallest among all engineering plastics, which has a certain effect on reducing the mass of the car and lowering the fuel consumption. If compared by unit volume, nylon 12 has advantages in price and performance. 2) Melting point The melting point of nylon 12 is 172-178℃, which is slightly lower than that of nylon 11, and it can fully meet the working temperature requirement of automobile fuel and air brake pipes. 3）Water absorption As we all know, the biggest drawback of nylon products is the large water absorption, and it is difficult to ensure the dimensional stability. However, due to the increase of methylene molecules in nylon 12, the influence of hydrophilic groups is greatly reduced, therefore, nylon 12 has the lowest water absorption rate among nylon products, which reduces the change of performance and size of products caused by water absorption, which makes nylon 12 have great advantages. After water absorption, the tensile strength of nylon 12 decreases very little, while nylon 66 and nylon 6 have great changes. 4) Impact strength Impact strength is an important technical index, and it is especially important for nylon 12 tubes that are often exposed to air. Nylon 12 at -20 ℃ and -40 ℃ according to the standard test, no fracture phenomenon, fully meet the requirements of use. Nylon 12 impact resistance is very good. 5）Low temperature performance Nylon 12 has the lowest brittleness temperature of -70 degrees Celsius, so it can be widely used for parts with low temperature resistance. 6) Flexibility The effect of plasticizers on the physical properties of nylon 12 is concentrated on the elastic modulus of the resin. There are three basic types of nylon 12 resins, the main difference between them is the different plasticizer content and the formation of different flexibility. As the content of plasticizer extractable components increases, the elastic modulus of the resin decreases. 7）Low abrasion and low friction properties Nylon 12 has excellent low-wear and low-friction properties and self-lubricating properties, so the frictional noise of Nylon 12 products is very low. 8）Fuel resistance In the automobile, the current use of oxygenated fuel, high aromatic fuel and alcohol mixed fuel will lead to the decomposition of many hose materials. Only nylon 11, nylon 12 and fluorocarbon elastomers have been tested for use in this environment. Under the action of motor fuels, all nylons dissolve, resulting in dimensional changes, especially in methanol-containing gasoline, where nylons containing large amounts of amide groups such as nylon 6 dissolve much more than nylons containing small amounts of amide groups such as nylon 12 %. It is found that the fuel containing 15% methanol has a great effect on nylon. 9) Resistant to zinc chloride solution Zinc chloride will appear in the environment under the car. Under certain temperature and humidity, the salt on the road reacts with galvanized steel or zinc-containing primer to form a small amount of zinc chloride. Zinc chloride is highly corrosive, but Nylon 12 is highly resistant to zinc chloride solutions. Ozone aging, UV exposure, temperature conditions, etc., can bring varying degrees of damage to parts and reduce service life. Since nylon 12 does not contain the + 2 3 2 + unsaturated double bond, which is susceptible to ozone attack, it does not suffer from ozone aging. In addition, the high crystallinity of nylon 12 and its high melting temperature make it more stable in terms of heat resistance, and the addition of heat stabilizers increases its heat resistance exponentially. When exposed to sunlight, its energy can cause the chemical bonds of organic materials to break. The bonding energy of C-H, C-O and C-N bonds in nylon 12 is so large that UV light is not enough to break them, but only the C-C bonds with smaller bonding energy; therefore, after adding appropriate anti-aging agents to the raw materials, the UV resistance of nylon 12 is excellent.

What is long chain nylon? It is a nylon with amide group in the main chain repeating unit of nylon molecule, the length of methylene group between two amide groups is more than 10. we call it long carbon chain nylon, including nylon 11, nylon 12, etc. It not only has most general properties of general nylon, such as lubricity, wear resistance, compression resistance, easy processing, but also has good toughness and flexibility, low water absorption, good dimensional stability, excellent of dielectric properties, good wear resistance and low density. Among the long-chain nylons, PA12 has the lowest water absorption, lowest density, low melting point, impact resistance, friction resistance, low temperature resistance, fuel resistance, good dimensional stability and good anti-noise effect compared with other nylon materials.PA12 has the properties of PA6, PA66 and polyolefin (PE, PP) at the same time. Due to the long methylene chain of PA11 and PA12 and the low density of amide in the molecular chain, PA11 and PA12 have similar performance. Compared with PA12, the disadvantage of PA11 is the low yield of ricinoleic acid and the expensive price, which limits the large-scale promotion of PA11. Polyamide 12 filling long glass fiber Glass fiber is an inorganic non-metallic material with excellent performance, is a natural mineral with silica as the main raw material, add specific metal oxide mineral raw materials, mixed uniformly, molten at high temperature, molten glass liquid flow through the funnel outflow, in the role of high-speed pull gravitational force is drawn and rapidly cooled and cured into a very fine continuous fiber. Glass fiber monofilament diameter from a few microns to more than twenty microns, equivalent to a hair of 1/20-1/5, each bundle of fiber original filament are composed of hundreds or even thousands of monofilaments. Glass fiber has high tensile strength, high elasticity coefficient, excellent characteristics such as non-combustibility, chemical resistance, low water absorption, and good processing performance, etc. It is usually used as a reinforcing material in composite materials and is widely used in various fields. Long Glass Fiber LFT Features and Benefits   -After glass fiber reinforcement, glass fiber is a high temperature resistant material, therefore, the heat resistance temperature of reinforced plastics is much higher than before without glass fiber, especially nylon plastics. -After glass fiber reinforcement, the addition of glass fiber restricts the movement of polymer chains between plastics, therefore, the shrinkage of reinforced plastics decreases a lot and the rigidity is also greatly improved. -After glass fiber reinforcement, the reinforced plastic will not be stress cracked, and the impact resistance of the plastic will be improved. -After glass fiber reinforcement, glass fiber is a high-strength material, which also greatly improves the strength of plastic, such as: tensile strength, compression strength, bending strength, much higher. -After the glass fiber reinforcement, the burning performance of the reinforced plastic decreases a lot due to the addition of glass fiber and other additives, and most of the materials cannot be ignited, which is a kind of flame retardant material.

Long carbon fiber Carbon fiber has many excellent properties, high axial strength and modulus, low density, high specific performance, no creep, super high temperature resistance in non-oxidizing environment, good fatigue resistance, specific heat and electrical conductivity between non-metal and metal, small coefficient of thermal expansion and anisotropy, good corrosion resistance, good X-ray transmission. Good electrical and thermal conductivity, good electromagnetic shielding, etc. Compared with traditional glass fiber, carbon fiber has more than 3 times of Young's modulus; it is about 2 times of Young's modulus compared with Kevlar fiber, which is insoluble and swollen in organic solvents, acids and alkalis, and has outstanding corrosion resistance. But is there a way to reduce the price of carbon fiber? That is to mix it with relatively cheap nylon material to form a composite material with good performance and meet the requirements. In that case, there is no doubt that carbon fiber nylon will definitely have a place in the composite material. Nylon itself is an engineering plastic with excellent performance, but moisture absorption, poor dimensional stability of products. Strength and hardness are also far from metal. In order to overcome these shortcomings, as early as before the 70s. People have used carbon fiber or other varieties of fibers for reinforcement to improve its performance. Carbon fiber reinforced nylon materials have developed rapidly in recent years, because nylon and carbon fiber are excellent performance in the field of engineering plastics materials, its compound material synthesis reflects the superiority of the two, such as strength and rigidity than unreinforced nylon is much higher, high temperature creep is small, thermal stability has improved significantly, good dimensional accuracy, wear resistance. Excellent damping, compared with glass fiber reinforced has better performance. Therefore, carbon fiber reinforced nylon (CF / PA) composites have developed rapidly in recent years. And for 3D printing using SLS technology is the most suitable technical means to achieve carbon fiber reinforced nylon.
