PLA information PLA, also known as polylactide, refers to the polyester polymer obtained by polymerization of lactic acid as the main raw material, usually using renewable plant resources (such as corn, cassava, etc.) made of starch as raw material. It is a new type of renewable biodegradable material. PLA material characteristics The raw materials are renewable and relatively easy to obtain even if used as 3D printing materials, which can be used for large-scale production; The PLA has good thermal stability and solvent resistance. The processing temperature of PLA is between 170 ℃ and 230℃, and the finished product has good heat resistance. Good permeability and transparency luster, can be processed by extrusion, spinning, biaxial stretching, injection blow molding and other ways, tensile and bending modulus can be comparable to the traditional plastic resin; High biocompatibility. The monomer material of PLA, L-lactic acid, is an endogenous active substance in human body. Therefore, the finished product printed by 3D printing material PLA is non-toxic to human body and can be absorbed by human body. It has good degradability. Different from the degradation methods of other 3D printing materials, PLA is embedded in the soil and completely degraded by microorganisms in nature under specific conditions to generate carbon dioxide and water. The carbon dioxide generated directly enters the soil organic matter or is absorbed by plants instead of being discharged into the air, which is recognized as an environmentally friendly material. Application of PLA materials Due to the good mechanical and physical properties of PLA material, PLA material is widely used, including various food containers, packaged food, fast food lunch boxes, etc.  At the same time, with its advantages in compatibility and degradability, PLA can also play a large role in the medical field, which can be made into medical tissue skeleton material and medical carrier for human body. In addition to its excellent tensile strength and extensibility, PLA can be produced by various common processing methods, such as melt extrusion molding, injection molding, blow film molding, foam molding and vacuum molding.

What is PPA? PPA (Polyphthalamide) is polyphthalamide. PPA is a kind of thermoplastic functional nylon with both semi-crystalline structure and non-crystalline structure. It is prepared by polycondensation of phthalic acid and phthalenediamine. It has excellent thermal, electrical, physical and chemical resistance and other comprehensive properties. It still has excellent mechanical properties, including high rigidity, high strength, high dimensional accuracy, low warping and stability, fatigue resistance and creep resistance, under the harsh working environment of continuous high temperature, humidity, oil pollution and chemical corrosion at 200℃. The main application is non-crystalline PPA. PPA has high hardness, excellent mechanical strength such as bending, tensile and impact at high temperature, and can resist tensile creep for a long time. Its rigidity and strength even exceed PPS and PEEK at the high temperature of 120℃. Especially suitable to replace die casting alloy to reduce cost. PPA has higher thermal stability than PA46, better arc resistance and infrared reflow welding ability of CTI. PPA has excellent resistance to gasoline, diesel, oil, mineral oil, transformer oil and other oils, even at high temperature of 150℃. PPA is suitable for long-term outdoor use without reducing physical properties even in extreme climate conditions such as high UV radiation, high humidity and high temperature. PPA resin is stronger and harder than fatty polyamides such as nylon 66; Less sensitive to water; Better thermal performance; And much better creep, fatigue and chemical resistance. The vast majority of PPA resins are processed by traditional injection molding. What is Long carbon fiber?

Polyphenylene sulfide is a new functional engineering plastic.

Long carbon chain nylon is nylon with an amide group in the main chain repeating unit of nylon molecule, and the length of methylene between the two amide groups is greater than 10. We call it long carbon chain nylon, including nylon 11, nylon 12, etc. PA12 is nylon 12, also known as polydodecactam, polylauractam, is a long carbon chain nylon. The basic material for its polymerization is butadiene, a semi-crystalline - crystalline thermoplastic material. Nylon 12 is the most widely used long carbon chain nylon, in addition to most of the general properties of nylon, low water absorption, and has high dimensional stability, high temperature resistance, corrosion resistance, good toughness, easy processing and other advantages. Compared with PA11, another long carbon chain nylon material, the price of butadiene, the raw material of PA12, is only one third of the price of castor oil, the raw material of PA11. It can replace PA11 and be applied in most scenes, and has a wide range of applications in automobile fuel pipe, air brake hose, submarine cable, 3D printing and many other fields. In long chain nylon, compared with other nylon materials, PA12 has great advantages, such as the lowest water absorption rate, the lowest density, low melting point, impact resistance, friction resistance, low temperature resistance, fuel resistance, good dimensional stability, good anti-noise effect. PA12 has the properties of PA6, PA66 and polyolefin (PE, PP) at the same time, achieving the combination of lightweight and physical and chemical properties, and has advantages in performance. There are a large number of non-polar methylene groups in nylon 12, which makes nylon 12 molecular chain more compliant. The amide group in nylon 12 is polar, and the cohesion energy is very large, it can form hydrogen bonds between the molecules, so that the molecular arrangement is regular. Therefore, nylon 12 has high crystallinity and high strength. Nylon 12 has low water absorption, good low temperature resistance, good air tightness, excellent alkali and oil resistance, medium resistance to alcohol, inorganic dilute acid and aromatic hydrocarbons, good mechanical and electrical properties, and is a self-flameout 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 quality of vehicles and reducing fuel consumption. When compared by unit volume, nylon 12 has advantages in price and performance. 2) Melting point The melting point of nylon 12 is 172-178℃, slightly lower than nylon 11, can fully meet the requirements of automobile fuel pipe and brake pipe working environment temperature. 3) Water absorption As we all know, the biggest disadvantage of nylon products is large water absorption, dimensional stability is difficult to ensure. And PA12 has the lowest water absorption rate of nylon products, this is due to the methylene molecules in nylon 12 greatly reduce the hydrophilic groups, which makes nylon 12 has a great advantage. 4) Impact strength Impact strength is an important technical index, especially for nylon 12 pipe often exposed to air. Nylon 12 under -20℃ and -40℃ according to the standard test, no fracture phenomenon, fully meet the requirements of use. Nylon 12 has excellent impact resistance. 5) Low temperature performance Nylon 12 has the lowest brittleness temperature of -70 degrees Celsius, so it can be widely used in low-temperature resistant parts. 6) Flexibility The influence of plasticizer on the physical properties of nylon 12 is concentrated on the elastic modulus of resin. Nylon 12 has three basic types of resin, their main difference is due to the plasticizer content of different forms of flexibility. The elastic modulus of resin decreases with the increase of extractable component content of plasticizer. 7) Low wear and low friction performance Nylon 12 has excellent low abrasion and low friction properties and self lubricating properties, so the friction noise of nylon 12 products is very low. 8) Fuel resistance In automobiles, the mixture of oxygenated fuel, high aromatic fuel and alcohol currently used can cause the breakdown of many hose materials. After the test, only nylon 11, nylon 12 and fluorocarbon resin elastomers can be used in this environment. Almost other types of nylon melt under the action of automobile fuel, resulting in a change in size. 9) Resistance to zinc chloride solution Zinc chloride is found under the car. Under certain temperature and humidity, the salt on the road reacts with galvanized steel plate or zinc-containing primer to form the corrosive zinc chloride. In addition, ozone aging, ultraviolet radiation, temperature conditions and so on, will bring different degrees of damage to the parts, reduce the service life. Nylon 12 is very resistant to zinc chloride solution. Because there is no unsaturated double bond in nylon 12 which is susceptible to ozone attack, ozone ...
