HP nylon PA12 is a kind of material that has very high strength and good heat resistance. HP has accumulated in the printing industry for a long time, which makes the multi-jet melt 3D printing technology using HP patented technology very suitable for small batch production.  The polyamide PA12 molecular backbone contains a large number of polar amide groups, which causes a strong force between polyamide molecules and can form hydrogen bonds(the greater the density of hydrogen bonds, the better the mechanical strength, the more carbon atoms, the worse the strength), At the same time, the polyamide PA12 molecules are arranged neatly and crystalline; The polyamide PA12 molecular main chain section also contains methylene, which makes the polyamide PA12 flexible and can affect the polyamide PA12 melting point and vitrification temperature.

Product Description

What's PA12?

PA12's scientific name is polydodecamide, also known as nylon 12. The basic raw material for its polymerization is butadiene, which can rely on petrochemicals. The reason why polyamide PA12 has developed so rapidly is inseparable from its unique structure: There are a large number of polar amide groups in the molecular backbone of polyamide PA12, which makes polyamide molecules strong. Force, And it can form hydrogen bonds(the greater the density of hydrogen bonds, the better the mechanical strength, the more carbon atoms, the worse the strength), and also make the polyamide PA12 molecules neatly arranged and crystalline; The polyamide PA12 molecular main chain segment also contains methylene, which makes the polyamide PA12 flexible and can affect the polyamide PA12 melting point and vitrification temperature(Tg); In addition, the terminal of the polyamide PA12 macromolecule main chain contains amino and carboxyl groups, which have a certain reaction activity under a certain line and are easily modified. These polyamide PA12 containing an amide group(-CONH-) structure has a series of excellent properties compared to other materials. Polyamide PA12 resin is a material with excellent comprehensive performance, but it also has obvious disadvantages, such as physical sensitivity to temperature, water absorption, dimensional stability, and low temperature toughness. Modification by chemical or physical methods can greatly improve its performance. For example, by adding glass fiber material, the water absorption and dimensional stability can be greatly improved, and the strength and toughness of the resin can be improved. Through mixing and copolymerization with other polymers, various alloys can be made to replace traditional materials such as metal and wood.

The difference between PA12 and PA11:

PA12 is a semi-crystalline-crystalline thermoplastic material. Its characteristics are similar to PA11, but the crystal structure is different. PA12 is a good electrical insulator and, like other polyamides, does not affect insulation performance due to humidity. PA12 has good impact resistance and chemical stability. PA12 has many improved varieties in terms of plasticization characteristics and enhancement characteristics. Compared with PA6 and PA66, these materials have lower melting points and densities and have very high return rates. PA12 has no resistance to strong oxidizing acids. The viscosity of PA12 depends mainly on humidity, temperature and storage time. It's very fluid. The shrinkage rate is between 0.5 % and 2 %, which mainly depends on the material variety, wall thickness and other process conditions. PA12 has low density, low melting point, high decomposition temperature, small water absorption, good low temperature resistance, and good noise protection. Good performance. PA12 products have good dimensional stability and are easy to form. PA12 is resistant to alkali, anti-fouling agents, and oil resistance. It is capable of alcohol, inorganic enoic acid, and aromatic hydrocarbons. It is not resistant to concentrated inorganic acids and chlorinated hydrocarbons and is soluble in phenol. PA12 has a relative density of 1.02 g/cm3, which is low in nylon products; Due to the low content of its amide group, the water absorption rate is 0.25 %, which is also low in nylon. PA12 has a thermal decomposition temperature greater than 350 °C and a long-term use temperature of 80-90 °C. The PA12 membrane has good airtightness and the water vapor transmission rate is 9g/m2. PA12 Alkali, oil, yeast and inorganic dilute acids, aromatic hydrocarbons, etc..

What are the applications of PA12?

PA12 is widely used in automobile fuel transmission pipes, automobile brake brake tubes, air conditioning tubes, air pressure equipment hoses, industrial high-pressure hydraulic tubes, pipe rapid joints, automotive anti-lock system spiral shafts, precision gears, cams and bearings. Sliding section, photocopier to electrostatic rotating roller, Static capacitor and IC chip guide rail, fiber optic cable cover, transparent tube, self-adhesive wire paint, VCD-ROM, printer / DVD-ROM muffler gear, sports soles, cable buckle, tennis racket buckle and many other aspects. PA12 can also be used to make fine parts for pipes, cable jackets to insulate conductors, medical catheters, and gears and valve covers in the mechanical and engineering fields. PA12 can replace PA11 in many ways, and it is more appropriate to replace polyformaldehyde at low temperatures. The weapons industry makes belts and other parts, It can also be used for the manufacture of various industrial precision parts and components and the manufacture of gears, bearings, screws, syringes, tool handles, hoses, cold-resistant tubing, pressure pipes, wire and cable covers, optical guide fiber maintenance kits and insulation parts, waterproof containers, valves, cabinets, etc.. Pipe, rod, board, food and packaging film can also be made. The transparent PA12 series provides excellent performance for the application of the eye industry. No other sunglasses and sports glasses lens materials have such a combination of integrated performance and high degree of comfort.

  • How does 3D printing work?

    3D Printing process builds an object layer by layer to create a complex shape. In order to build this object we need a 3D file that contains accurate information about the geometry of the part. Then the information in this 3D file is sent to the 3D-printer that will build up the material matching the 3D file.

  • What is 3D printing?

    3D printing is a digital manufacturing process that makes it possible to create a physical object from a 3D file. The object is formed by applying successive layers of solid material. 3D Printing also known as Additive Manufacturing(AM) as a general term that covers various techniques and it empowers designers and manufacturers print object of any shape and geometric dimension. In simple words, it is one of the fastest modes of developing physical prototypes accurately and true to scale.
