Polyamide resin, English name is polyamide, abbreviated as PA.. Nylon, commonly known as the main chain repeat units of macromolecules containing amide groups of polymers collectively. For the five engineering plastics in the largest yield, the most varieties, the most widely used varieties. Nylon 6 is polycaprolactam, while nylon 66 is polyadipic diamine adipate. Nylon 66 is L2% harder than nylon 6; Followed by Nylon 11, nylon 12, nylon 610, nylon 612, nylon 1010, nylon 46, nylon 7, nylon 9, nylon 13, new varieties are nylon 6i, nylon 9t and special nylon MXD6(barrier resin) , etc. . There are many varieties of nylon modified, such as reinforced nylon, monomer cast nylon (MC Nylon) , Reaction injection molding nylon (RIM) , aromatic nylon, transparent nylon, high impact (ultra-tough) nylon, electroplated nylon, conductive nylon, flame retardant nylon, nylon and other polymer blends and alloys, to meet different special requirements, widely used as metal, wood and other traditional materials substitutes. Density (g/cm3)1.10-1.14; tensile strength (MPa)60.000. 0-80.0, Rockwell hardness 118, melting point 252 ? ° C, embrittlement temperature -30 ? ° C, thermal decomposition temperature greater than 350 ? ° C, continuous heat resistance 80-120 ? ° C, impact strength (KJM2)60-100, static bending strength (MPa)100-120, Martin heat resistance (? ° C)50-60; The bending modulus of elasticity (MPa) is 2000 ~ 3000, the volume resistivity (ωcm) is 1.83 × 1015, the equilibrium water absorption is 2.5% , and the dielectric constant is 1.63. The bending modulus of elasticity (MPa) is 2000 ~ 3000, the volume resistivity (ωcm) is 1.83 × 1015, the equilibrium water absorption is 2.5% , and the dielectric constant is 1.63. Chemical formula: [-NH (CH 2)6-NHCO (CH 2)4CO ] n-resistant to acid, alkali, most of the inorganic salt solution, haloalkanes, hydrocarbons, esters, ketones and other corrosion PA66 in Polyamide material has a high melting point. The shrinkage rate of PA66 was between 1% and 2% . There are many disposable nozzles on the market that can be modified to achieve the same physical properties of raw materials. At the same time, the price is also relatively much cheaper than the raw materials, thus saving a large amount of costs for our customers, warm Tip: because the plastic market will change every day, some pages may be different with the actual price of the day, for reference only! Price to the market on the same day shall prevail, Welcome to inquire!
