Nylon PA66 US 101 performance is: opaque semi or transparent milky white crystalline polymer with plasticity. Melting point 252 ℃. Brittle temperature -30 ℃. Density 1.15g/cm3. The thermal decomposition temperature is greater than 350 ℃. Continuous heat resistance of 80-120 ℃, equilibrium water absorption rate of 2.5%. It is resistant to acid, alkali, halogenated hydrocarbons, hydrocarbons, most inorganic salt solutions, ketones, esters, and other corrosive substances, but is easily soluble in polar solvents such as. Has excellent self-lubricating properties, wear resistance, and high mechanical strength. However, due to its high water absorption, its dimensional stability is poor.

Injection characteristics of nylon PA66 US 101 plastic: Drying treatment: If the material is sealed before processing, there is no need to dry it. Therefore, if the storage container is opened, it is recommended to dry it in hot air at 85C. If the humidity is greater than 0.2%, it is necessary to perform 105C and 12 hours of vacuum drying.
Melting temperature: 260~290C. For glass additive products, it is 275~280C. The melting temperature should avoid exceeding 300C.
Mold temperature: It is recommended to be 80C. Crystallinity is affected by the mold temperature, and crystallinity will also affect the physical properties of the product. For
Thin walled plastic parts, if a mold temperature lower than 40C is used, the crystallinity of the plastic part will change over time. In order to maintain
The geometric stability of plastic parts requires annealing treatment.
Injection pressure: usually between 750 and 1250 bar, depending on product design and materials.
Injection speed: High speed (slightly lower for strong materials).
Runner and sprue: Due to the short solidification time of PA66, the position of the sprue is very important. The aperture of the gate cannot be less than 0.5 * t (t represents the thickness of the plastic part). If a hot runner is used, the gate size should be smaller than using a conventional runner, as the hot runner can help prevent premature solidification of the material.

If a submerged gate is used, due to its high crystallinity, it has high rigidity and heat resistance.

Zytel USA PA66 Part Models and Performance:

Nylon PA66 USA 101 (polyamide 66 or nylon 66), compared to PA6, PA66 has a wide range of applications and is used in the automotive industry, instrument housings, and other products that require impact resistance and high strength. It can also be used for manufacturing mechanical production, various parts of automobiles, electrical and chemical devices, such as impellers, fan blades, high-pressure seals, gears, rollers, pulleys, roller shafts, valve seats, various handles, gaskets, bushings, support frames, inner layers of wire packages, etc. in pump bodies.
Nylon PA66 US 101 specific properties: The higher melting point of PA66 plastic is reflected in polyamide materials. PA66 can maintain strong stiffness and strength at higher temperatures. It is a semi crystalline crystalline material. The formed PA66 plastic has hygroscopicity, which mainly depends on the composition of the material, wall thickness, and environmental conditions. During product design, it is necessary to consider the impact of moisture absorption on geometric stability. PA66 plastic has relatively low viscosity, so its flowability is good (but not as good as PA6). PA66 plastic can be used to process very thin components. Its viscosity is very sensitive to temperature changes. The shrinkage rate is between 1% and 2%, and adding glass fiber additives can reduce the shrinkage rate to 0.2% to 1%. The difference in shrinkage rate between the process direction and the perpendicular direction is significant.
Nylon PA66 USA 101 Application: High temperature electrical socket parts, bearings, rollers, electrical parts, gears, bolts, impellers, fan blades, propellers, spring brackets, pulleys, high-pressure sealing gaskets, valve seats, oil pipes, grinding wheel adhesives, battery boxes, oil storage containers, drive belts, ropes, zip ties, insulated electrical parts, wire cores, wire drawing, etc.
