Polyamide (PA) or Nylon: Complete Guide (PA6, PA66, PA11, PA12…)

Applications of Polyamide/Nylon Products

Plastic parts are made with polyamides are used in various industries like transportation, electronics & electrical, consumer goods, building & construction and packaging. They can also be a good alternative to metal when filled with glass fibers. Explore some of the key applications where polyamides have proven to be the material of choice.

Overview

Key Applications

Applications of PA6 & PA66


PA66 is used when PA6 reaches its limit temperature or when the hydrolytic stability of PA6 is not sufficient anymore. It provides good surface appearance and weld strength leading to burst pressure resistance. The molding cycles are quick, providing an economical interest. Polyamide 6 and Polyamide 66 answer the requirements of numerous applications in the varied markets.

  • PA6, PA66 Replace Metal in Automotive Applications - Thanks to their good processability, PA6 and PA66 are often used as an alternative to metal in automotive under the hood parts where design flexibility as well as temperature and chemical resistance are critical. They ultimately contribute to weight savings, which offers CO2 emissions reduction opportunities. PA66's mechanical properties (stiffness, creep resistance, etc.) help improve safety and comfort in cars.

  • Electrical & Electronics Applications - Flame Retarded PA Works Well - In the electrical and electronic applications, Polyamides 6 and 66 grades are good candidates where specific tests (GWIT, UL94) need to be passed. PA6 & PA66 can easily be flame retarded and halogenated & non-halogenated FR solutions are commercially available. Moreover, they also bring solutions in this industry where miniaturization reinforces the needs for high temperature resistance and thin designs (possible due to easy processability).

  • Good Surface Aspect in Consumer Applications - Polyamide 66 offers solutions for durable Consumer and Industrial Goods, thanks to its easy moldability, colorability, good surface aspect and excellent mechanical resistance. PA66 is an excellent material when complex designs are needed, and it is also a cost efficient solution.

  • Food Packaging with PA6 & PA66 - PA6 and PA66 offer very high puncture resistance, barrier resistance to oxygen, carbon dioxide and aromas, transparency, etc. All these properties make PA6, PA66 ideal for use in food packaging (mono or multi-layer). In the medical field, PA6 is fabricated into tough, puncture-resistant packages for medical blister packs.

  • PA Replaces PP in Furniture Applications - For the furniture market, PA6, PA66 is used to manufacture stadium seats thanks to their brilliant surface quality, excellent resistance to dirt and aging and offering a great alternative to polypropylene.

  • Sports & Leisure - The exceptional fatigue properties and high impact and mechanical strength of PA6 and PA66 contribute in sports applications where they are used to manufacture Ski bindings.

  • Other applications include agricultural films, liquids packaging, protective packaging, medical, etc.


Applications of PA 11/PA12


The superior properties of PA11/ Nylon 11 and PA12/Nylon 12 make them useful in applications like:

PA11 applications

  • Automotive - Due to its aigh flexibility and tensile strength, PA11/ Nylon 11 is used to manufacture trailer brake hoses, fuel lines, etc. for the automotive/transportation market.

  • Sports and Leisure - PA11/ Nylon 11 is used to manufacture bicycle derailleur, sport shoes (football shoe soles), etc., thanks to its good grease and abrasion resistance and low coefficient of friction

  • In engineering/ manufacturing applications like protective layer of water pipes, air and spray-painting hoses, PA11/ Nylon 11 is widely used

  • Other applications include healthcare/medical (catheters), appliances (protective coating of dishwasher racks), electrical markets (coatings for termite resistant wires), household products/consumer goods (hammer heads), etc.

There are also some specialty PA 11 grades developed for 3D printing offering benefits such as:
  • Good control of particle size
  • Good thermal properties, 
  • Very good processability in laser sintering machines


Applications of Polyamide 46


Polyamide 46 (PA46) is a high temperature polyamide providing unmatched performances across a broad range of applications.

  • Automotive - It is used to manufacture several automotive/ transportation parts like chain tensioners, engine covers, oil filter parts, signaling lamp bases, thrust washers, gear-shift forks, speedometer gear wheels, fuel distributors, etc.

  • Electrical and Electronics - It is used to manufacture surface-mount devices, connectors, end laminates in electric motors, brush holders in electric motors, etc. for the electronics market
  • Industrial goods, , consumer goods, safety controls in appliances such as kettles and ovens
  • And many more…


Applications of Polyphthalamide (PPA)


PPA Grades deliver cost effective solutions, compared to PA46, in many applications as listed below.

  • Many types of automotive components including sensors and solenoids, halogen lamp sockets and fog lamp assemblies, motor end caps and housings, fuel system components (flanges, fuel rails, fuel line connectors), anti-lock braking system components, cooling and heating system components (thermostat housings, oil filter housings, turbo charger air coolers).

    Polyphthalamide is also used in a range of high temperature applications in the automotive electronics sector such as lamp sockets, electronics connectors, high-temperature switches, and sensors.

  • Electrical and Electronics Market - Main applications include LEDs and other optoelectronic devices, SMT electronic components, capacitor and chip carriers, heat sinks and switches. PPA resin is also surface mount compatible and, with its outstanding strength and ability to be injection molded with fast cycle times, is an excellent fit for applications such as cellular phone connectors.

    Finally, fully automated wafer loading systems use cassettes molded from Polyphthalamide resin to transport silicon wafers into process equipment where heat and chemical resistance are required.

  • Other markets benefiting from PPA resin benefits are: optics (optical fiber components), hardware and plumbing, sporting goods, oil field parts, and military applications.

They can also be a good alternative to metal when filled with glass fibers.
