Engineering plastics
PA6 PA6 is a translucent or opaque opalescent crystalline polymer. PA6 has high mechanical strength, good impact resistance, excellent wear resistance and self-lubrication. The friction coefficient of oil-free lubrication is about 0.2. PA6 has good heat resistance, melting point is 220C, lower than PA46, PA66, higher than other varieties, with self-extinguishing. Good electrical insulation performance. PA6 has excellent resistance to aliphatic hydrocarbons, especially gasoline and lubricants, alkali and most salts, but is dissolved in concentrated inorganic acids, formic acids and phenolic compounds.
PA6 has high water absorption and poor dimensional stability. The performance of PA6 is greatly affected by temperature and water absorption. In the range of operating temperature, the tensile strength, bending temperature and bending modulus decrease with the increase of temperature, while the tensile strength is greatly affected by water absorption and decreases with the increase of water absorption. The impact strength increases obviously with the increase of temperature and water absorption. The volume resistivity decreases with increasing temperature and water absorption. Engineering plastics PA6 can be used in the manufacture of gears, bearings, pulleys, pump impeller, fan blades, fastener, screw, nut, high pressure sealing ring, oil seal, piston, such as mechanical parts, chemical equipment in the pipeline, storage tank, filters, cut-off valve, the car radiator box, adsorption tank, fuel filter, wheel cover, car plate, etc., Switches, relays, terminals, microwave oven housings, etc.
Engineering plastics PA66 PA66 is a translucent or opaque milky white crystalline resin, which is the earliest polyamide variety developed. PA66 has high strength, rigidity and toughness in a wide temperature range, strength and rigidity are higher than PA6, impact resistance is lower than PA6, with excellent wear resistance and self-lubrication. The friction coefficient for steel is 0.25 and decreases to 0. 12 under oil lubrication condition. The fatigue resistance and creep resistance of steel are better than that of PA6. PA66 has excellent heat resistance, melting point is 260C, only lower than PA46, is a self-extinguishing material. PA66 for gasoline
And lubricating oil has excellent resistance, can withstand dilute inorganic acid, alkali and alcohol, ketone, aromatics and other solvents, but soluble in phenol, formic acid and other polar solvents. Electrical insulation is good.
The water absorption of PA66 is large, and the dimensional stability of the product is poor. The tensile strength and bending strength decrease with the increase of temperature and water absorption, and the impact strength increases significantly with the increase of water absorption. Electrical insulation decreases with increasing temperature and water absorption. Engineering plastic PA66 is widely used in manufacturing bearings, bearing recage, bearing bush, bushing, turbine, CAM, pump impeller, cylinder cover, sealing gasket, valve, piston, bolt, nut and other mechanical parts. Used in the manufacture of the radiator box in the car, heater, radiator panel, front grille, steering column cover, tail lampshade, adsorption tank, all kinds of pulleys, window handles, window bolt, all kinds of gears, bearings, etc., used in the manufacture of power tools in the electrical cover cover, motors, sensors, frame, coil winding pipe, electric switch, shell, etc., In the field of construction, it can be used to manufacture window frame buffer, door pulley, curtain guide pulley, escalator railing, lift parts, heat insulation window frame, etc.
