About polyamide (PA):
Polyamide (nylon) is one of the most widely used engineering thermoplastics in the world. PA6 and PA66 offer an outstanding balance of mechanical strength, toughness, heat resistance and chemical resistance at competitive cost. Modified with glass fibre, flame retardants, impact modifiers and specialty additives, our PA compounds deliver tailored performance for automotive, electrical and electronic, industrial and consumer applications.
Key Performance Features
Why PA6 and PA66 are the most versatile engineering thermoplastics
Excellent Mechanical Strength
PA6 and PA66 offer outstanding tensile strength (60-85 MPa) and impact resistance. Glass fibre reinforcement can raise strength beyond 200 MPa, ideal for structural applications.
Chemical & Oil Resistance
Strong resistance to oils, greases, fuels, alkalis and organic solvents. An ideal material for automotive engine-bay parts and industrial environments.
Flexible Processing
Excellent flow for thin-wall injection moulding. Wide processing window with melt temperatures of 230-290°C. Suitable for complex geometries and multi-cavity moulds.
Good Wear Resistance
Inherently wear resistant with a low coefficient of friction. Ideal for gears, bearings, rollers and sliding parts in mechanical assemblies.
High Stiffness When Filled
Flexural modulus from 3,000 MPa (unfilled) to 15,000+ MPa (GF reinforced). Fibre content selectable from 5%-60% to tailor stiffness for load-bearing uses.
Wide Temperature Range
Standard grades serve continuously from -40°C to 120°C. Heat-stabilised grades extend to 150°C. Ductility is retained even in sub-zero environments.
PA Product Series
4 proprietary modified series covering every application scenario
Flame-Retardant PA6/PA66

Flame-Retardant PA66 Import Substitution
Flame-retardant PA66 / PA6 series, customisable to your sample requirements
Best Plastics supplies flame-retardant PA66 / PA6 series (PA66-6 series) in both halogenated and halogen-free systems, with UL94 V-0 covering 0.8-3.0 mm wall thickness. Products comply with EU environmental regulations (RoHS, REACH) and we provide glow-wire (GWFI / GWIT) and needle-flame test reports to meet the fire-safety requirements of home appliances, low-voltage electrical gear and connectors.
Beyond our standard grades, we can compound to your physical sample or datasheet — send us the imported grade or a sample part; we run trial shots comparing flame rating, glow-wire temperature, mechanical data and flow before you commit to volume.

PA6 PA66 FAQ
Common questions on grade selection, flame retardance, import substitution and certification
What is the difference between PA6 and PA66?
PA66 has a higher melting point (255-265°C versus 215-225°C for PA6), higher tensile strength and better heat resistance; PA6 offers slightly better impact resistance, surface finish and processability with a wider moulding window. The choice depends on your specific temperature, strength and appearance requirements — PA6/PA66 blends can also deliver intermediate performance.
Which glass fibre content should I specify?
GF15-20%: moderate strength gain with good surface finish; GF30%: the best balance of strength, stiffness and processability, and the most common specification; GF40-50%: maximum strength and stiffness for structural parts; GF60%: ultra-high stiffness with some sacrifice in toughness. Best Plastics can customise any content between 5% and 60%.
Which imported grades can your flame-retardant PA66 replace?
Our flame-retardant PA66 / PA6 series can be matched against virgin imported grades such as Toray 66/3004-V0 and CM1014-V0, BASF 66/C3U and A6B3U, Solutia PA66/M344, DuPont FR7025, Asahi Kasei FR370, Rhodia 6/C50H1, 6/C50H2, 66/A50H1 and 66/B50H1, A. Schulman MV 14 FR and DSM 1010N2. You provide the grade or a physical sample; we compare flame rating, glow-wire temperature and mechanical data, then propose the corresponding KLD grade, re-compounding and re-trialling where necessary. We have no licence or agency from the original makers — we recommend mould trials and certification checks before switching.
Do the grades pass glow-wire and needle-flame tests?
Yes. Best Plastics flame-retardant PA66 / PA6 series complies with EU environmental regulations (RoHS, REACH). Per grade we can provide glow-wire flammability index (GWFI) and glow-wire ignition temperature (GWIT) test reports as well as needle-flame test reports, with UL94 V-0 covering 0.8-3.0 mm wall thickness. If you need reports at specific temperature points (e.g. 750°C / 850°C / 960°C), note it in your inquiry and we will issue them per grade.
Do you offer custom colours and performance for PA?
Yes. Colours can be natural, black or any RAL / Pantone code. On performance we can adjust glass fibre content, flame-retardant system (halogenated / halogen-free), impact modification, hydrolysis resistance, weathering resistance and anti-static additive packages, and we can replicate a one-to-one formulation from your sample.
What certifications do your PA products hold?
Our PA products are certified to SGS, RoHS, REACH, UL, ISO 9001 and ISO 14001, with flame-retardant grades passing UL94 V-0 at the specified wall thickness. FDA-compliant grades are available on request for food-contact applications. Batch COAs accompany every volume shipment.
