Pa6 vs pa66


Poly hexamethylene adipamide is also known as the polyamide 66PA66nylon 66which is made by polycondensation of adipic acid and hexamethylene diamine. Nylon 66 is a translucent or opaque milky crystalline polymer, and it emits purple or blue-white light when exposed to ultraviolet light. Nylon 66 has high mechanical strength and good resistance to stress cracking. It has the best wear resistance among all the nylons, and its self-lubrication is only secondary to polytetrafluoroethylene and polyoxymethylene.

Its chemical stability is good and its oil resistance is excellent, but it is easy to dissolve in polar solvents such as phenol formic acid. The addition of carbon black can improve the weather resistance of PA66, therefore, its dimensional stability is poor and the processing ability is good. PA66 can be used in injection molding, extrusion, blow molding, spraying, casting molding, machining, welding and bonding.

Typical Application Range of PA Compared with PA6, PA66 is more widely used in the automotive industry, a linear extrapolation method for a general phase relaxation problem shell and other products that needs impact resistance and high strength requirements.

Drying: Drying is not necessary if the material is sealed before processing, drying is not necessary.

Read more. Akulon is ideal for injection molding thanks to its unique combination of short- and long-term low and high temperature properties under various chemical conditions. For even higher temperatures, a material like our super heat-resistant Stanyl polyamide 46 is ideal, for example, in part fabrication where secondary processing under high temperatures happens, such as soldering in electrical applications.

Because polyamide 66 absorbs less than polyamide 6, its performance is slightly better. However, for reinforced materials, higher fill levels in polyamide 6 mean grades that deliver the same performance as a polyamide 66, with a lower level of reinforcement. This offers benefits in terms of stiffness, but disadvantages in terms of part weight and design flexibility. Polyamide 6 has better ductility than polyamide At lower temperatures this makes it a tougher material — less impact sensitive, less notch sensitive and with ductile behavior at lower temperatures.

The result: Safer parts less risk of splintering at low temperatures and lower breakage levels during processing because parts are tougher coming out of the mold. For unmodified grades where lower temperatures are found, polyamide 6 provides the better performance.

Typical applications for this low temperature performance are power tools, ski and snowboard bindings, and automotive exterior parts. Akulon performs over a wide temperature range.

Close Start Chat.Its impact resistance and anti-solubility better than PA66, but also more hygroscopic. In order to improve the mechanical properties of PA6, often add a variety of modifiers. Adding glass fiber additives can reduce shrinkage to 0. Molding shrinkage is mainly due to the material crystallinity and hygroscopicity.

PA66 toughened. PA6 GF Injection molding process conditions: Drying: PA6 is very easy to absorb moisture, so dry before processing with special attention.

If the material is supplied with water-resistant material, the container should be kept closed. If the humidity is greater than 0. Mold temperature significantly affects the degree of crystallinity, which in turn affects the mechanical properties of the part. The crystallinity is important for the structural components, so a mold temperature of C is recommended.

La différence entre PA66 et PA6

For thin-walled, long-range plastic parts also recommend the application of higher mold temperature. Increase the mold temperature can increase the strength and stiffness of plastic parts, but reduces the toughness.

For glass reinforcement mold temperature should be greater than 80C. Injection speed: High speed slightly lower for reinforced materials. Runners and gates: Due to the short setting time of the PA6, the position of the gate is very important.

Gate aperture not less than 0. If submerged gates are used, the minimum gate diameter should be 0. PA66 has a higher melting point in polyamide materials. It is a semi-crystalline - crystalline material. PA66 also maintains strong strength and stiffness at higher temperatures. In product design, we must consider the hygroscopicity on the geometric stability. In order to improve the mechanical properties of PA66, often add a variety of modifiers.

PA66 has low viscosity and therefore good fluidity but not as good as PA6. This property can be used to process very thin components. Its viscosity is sensitive to temperature changes. The addition of glass fiber additives can reduce the shrinkage to 0. Shrinkage in the flow direction and the flow direction of the vertical difference is larger.

PA66 is resistant to many solvents but less resistant to acids and some other chlorinating agents. Injection molding process conditions: Drying: If the material is sealed before processing, then there is no need to dry.

However, if the storage container is opened, it is advisable to dry it in 85C hot air. Melting temperature should be avoided above C. Mold temperature: Recommended 80C. Mold temperature will affect the degree of crystallinity, and crystallinity will affect the physical properties of the product.

Injection speed: high speed for reinforced materials should be slightly lower. Runner and gate: Due to the short setting time of the PA66, the position of the gate is very important.The differences are small, however, and in some circumstances, some of the items on the list above may be invalid, depending on the exact grade in use.

PA 66- Nylon 66

Good bearing properties; low friction, low wear. PA6 absorbs moisture which might decrease its strength and tensile modulus by half. The surface of the components feels slightly oily. This, in some cases, might not give the desired quality appearance. Slightly better short term thermal resistance Absorbs slightly less moisture Higher modulus Better wear resistance Better short term heat resistance Why not choose?

Higher price than PA6 not dramatically, might be worth the money For visual parts, PA6 has slightly better surface quality and processability Typical applications: Cable ties Ski bindings The differences are small, however, and in some circumstances, some of the items on the list above may be invalid, depending on the exact grade in use.

The difference can be felt when a product that has been stored outdoors over winter is taken indoors for a few days: its stiffness invariably increases. High-quality cable ties are made of PA This illustrates well the strength and toughness of the material.Polyamides belong to the group of engineering plastics.

Due to their characteristics and price performance ratio, most common used polyamides are PA6 and PA This goes along with the question, which differences between the two plastics exist. Both plastics are partially crystalline and have the same base, but with a different order of the single molecules.

Basic properties such as the chemical resistance are thus identical. Both polymers have good sliding and damping properties, good abrasion and impact resistance and are resistant to weak alkalis, grease, oils and fats. The different arrangements of the molecules lead to light mechanical benefits for the PA In addition, PA66 absorbs less moisture and is therefore inherently stable. Advantages of PA6, in particular for the glass fiber reinforced grades, are a better surface finish, which depends on the slower melt solidification.

In addition, the lower processing temperatures of PA6 lower the energy consumption which leads to lower production costs compared to PA Because of the higher moisture absorption, PA6 has an higher impact resistant than PA By adding glass fibers, the mechanical properties can be improved and the operating temperatures can be increased.

In addition geba also produces high-impact, heat and hydrolysis-stabilized polyamides in all desired colors. PA6 and PA6. Due to their mechanical and thermal properties and oil and grease resistance, the polyamides are applied for enclosures for power tools, pump housings, screws, gears, tanks, fittings, components in the engine compartment, fuel lines and fender.
