family: polyamides
name: Polyamide 66, 30% glass fibre reinforced (PA66-GF30, Nylatron GF30, TECAMID 66 GF30)
abbreviation: PA66-GF30
role: glass-filled engineering thermoplastic for machined structural and wear parts
category: composites
type: glass-fiber-reinforced
summary: |
  PA66-GF30 is polyamide 66 (nylon 66) filled with 30% glass fibre. Two datasheets read for this profile give a density of 1.29 g/cc for Nylatron GF30 (Mitsubishi Chemical Advanced Materials) and 1.34 g/cm3 for TECAMID 66 GF30 (Ensinger), so the sheets disagree. Mitsubishi gives a flexural modulus of 4.48 GPa and a heat deflection temperature of 204 °C at 1.8 MPa, and it rates strong acids and strong alkalies as unacceptable.
best_for: 'Stiff, heat-tolerant machined parts and gears: 4.48 GPa flexural modulus and 204 °C heat deflection at 1.8 MPa (Mitsubishi Nylatron GF30)'
weakest_at: Water uptake and heat over the long-term limit of 104 °C in air (Mitsubishi), with strong acids and strong alkalies rated unacceptable

gaps:
  - No flight, vacuum, radiation or outgassing result for this grade was read in this run. NASA TM-2008-215490 lists neat PA 66 (without glass fibre) in its erosion table, but the value is printed in exponent notation, so it is not recorded, and it is not this grade.
  - Surface and volume resistivity in both datasheets are printed in exponent notation, so they are not recorded.
  - The TECAMID sheet prints the linear CTE in exponent notation, so only the Nylatron CTE is recorded.
  - The handling sheet prints density and melting range with no unit, so neither is recorded. Its thermal decomposition and ignition temperature figures use no canonical property name, so they are not recorded.
  - PubChem GHS data could not be read (the site blocked automated access). The hazard entries rest on a handling sheet for a different maker's glass-fibre PA 66 grade, not on an SDS for Nylatron GF30 or TECAMID 66 GF30.
  - No producer tonnage or country share for nylon 66, hexamethylenediamine or glass fibre was found on a primary source. The supply entries rest on Wikipedia articles, which give no current shares.
  - The chemical resistance ratings come from the datasheet words Acceptable, Limited and Unacceptable, mapped to the corrosion scale. No numeric retention or immersion test was printed.
  - The two datasheets disagree on density, water uptake, tensile modulus and elongation. Both values are kept side by side, and neither is preferred.
  - The TECAMID sheet's Izod impact (ASTM D 256) and the Mitsubishi Rockwell M hardness have no canonical property name, so they are not recorded.
  - The Mitsubishi tensile strength row does not print a test temperature, so it is recorded as not printed.
  - 'A third maker''s datasheet for this grade (for example BASF Ultramid A3WG6 or an Ertalon 66 GF30 sheet) could not be fetched: the sites returned 403 or 404 in this run.'
  - The Wikipedia article on glass fibre does not cover the role of glass fibre in polyamide, and no polyamide-specific glass fibre source was read.
  - No CAS number for polyamide 66 or for this grade was read in this run.

  note: 'Read by an AI assistant on 2026-11-01 from the two PA66 GF30 datasheets and the handling sheet, plus Wikipedia for composition and production only. Unreachable: PubChem (blocked), BASF Ultramid page (404), materialhub Ertalon page (403), ULProspector Schulamid page (403). The density, water uptake and tensile modulus disagree between the two datasheets, and both values are kept.'
story:
  recipe:
    line: 'PA66-GF30 is polyamide 66 (nylon 66) filled with 30% glass fibre. Polyamide 66 is made by polycondensation of hexamethylenediamine and adipic acid, and the glass fibre is mixed in as a reinforcing filler. Two datasheets cover this grade: Nylatron GF30 (Mitsubishi Chemical Advanced Materials) and TECAMID 66 GF30 (Ensinger).'
    parts:
      - name: Polyamide 66 (matrix)
        symbol: (C12H22N2O2)n
        role: The continuous plastic matrix. Its repeat unit joins a six-carbon adipic segment and a six-carbon diamine segment through amide (-CO-NH-) groups, and the matrix holds the fibres in place.
        share_note: Repeat unit and formula as printed in the Wikipedia nylon 66 article
      - name: Glass fibre (filler)
        symbol: SiO2-based glass
        role: Reinforcing filler at 30% of the compound, as printed in both datasheets. Glass fibre is strong in tension, and combined with the resin it resists both tensile and compressive loads.
        share_note: 30% glass fibre by the grade name
  risk_groups:
    - title: For people
      level: 0
      verdict: Not classified hazardous in the sheet we read
      lead: The handling sheet for a glass-fibre PA 66 from another maker says the product is not subject to labelling. No GHS record for this grade was read.
      points:
        - label: Classification
          line: The handling sheet prints 'none' for special risks and for components subject to labelling, and it classes the product as an article exempt from REACh registration.
        - label: Fire
          line: Burning gives carbon monoxide, nitrogen oxide and traces of hydrogen cyanide, according to the same sheet (section 7). Firefighters should wear breathing apparatus.
    - title: Water
      verdict: The two sheets disagree on water uptake
      lead: The datasheets for the two makers print different water uptake figures under similar test wording.
      points:
        - label: After 24 hours
          line: Mitsubishi prints 0.30 % after 24 hours' immersion. Ensinger prints 0.25 % at 24 hours, both by ASTM D570.
        - label: At saturation
          line: Mitsubishi prints 5.5 % at saturation and Ensinger prints 0.30 %. The figures were not averaged, and the test wording differs between the sheets.
    - title: If it overheats
      verdict: Long-term service limit of 104 °C in air
      lead: The limits are set by the datasheets, not by a field incident.
      points:
        - label: Long-term limit
          line: Mitsubishi prints 104 °C as the long-term maximum service temperature in air, and 204 °C as the deflection temperature at 1.8 MPa. Ensinger prints 230 °F for long-term service and 338 °F for intermittent service.
  why: PA66-GF30 is a glass-filled nylon for machined structural and wear parts that need stiffness and heat tolerance. Mitsubishi gives a flexural modulus of 4.48 GPa for Nylatron GF30, and Ensinger gives 681000 psi for TECAMID 66 GF30. Both makers aim the grade at gears, structural housings and other engineering parts, and both give a glass content of 30%.
  uses:
    - where: Gears and wear parts
      line: Ensinger lists gear manufacturing and excellent wear properties among the target industries for TECAMID 66 GF30.
    - where: Machined structural parts
      line: The same sheet lists power engineering, the automotive industry and the construction industry among the target industries for this grade.
  can_do:
    - label: Stiffness
      benchmark: flexural_modulus
      value: 4.48 GPa flexural modulus (Mitsubishi)
      line: Nylatron GF30 has a flexural modulus of 4.48 GPa at the ASTM D790 test, and a flexural strength of 145 MPa.
    - label: Heat under load
      benchmark: heat_deflection_temperature
      value: 204 °C at 1.8 MPa
      line: Nylatron GF30 has a deflection temperature of 204 °C at 1.8 MPa under ASTM D648.
    - label: Long-term heat limit
      benchmark: max_service_temp
      value: 104 °C in air
      line: Mitsubishi prints 104 °C for long-term service in air, lower than its 204 °C deflection temperature under load.
  compare: The two sheets for this grade differ most in water uptake, density and elongation, so the rows show each maker's printed values and are not a ranking. The Mitsubishi sheet gives a density of 1.29 g/cc, and the Ensinger sheet gives 1.34 g/cm3. Both figures were kept rather than averaged.
  compare_rows:
    - label: Density
      benchmark: density
    - label: Heat deflection temperature
      benchmark: heat_deflection_temperature
    - label: Tensile modulus
      benchmark: elastic_modulus
  handling:
    - Store horizontally, dry and protected against climatic influences, as the handling sheet advises.
    - Bring the stock to room temperature, or store it at least 24 hours under normal climatic conditions, before machining.
    - Keep long-term service at or below 104 °C in air, as Mitsubishi prints.
  good_for:
    - 'Stiff machined parts: 4.48 GPa flexural modulus and 204 °C deflection at 1.8 MPa (Mitsubishi Nylatron GF30).'
    - 'Wear parts: Ensinger lists excellent wear properties and gear manufacturing as target uses for TECAMID 66 GF30.'
  watch_out:
    - 'Water uptake: 5.5 % at saturation on the Mitsubishi sheet, against 0.30 % on the Ensinger sheet.'
    - Strong acids and strong alkalies are rated unacceptable for this grade.
    - Density and tensile modulus differ between the two sheets, so check the sheet from your supplier before design.
  verdict: PA66-GF30 is a stiff, glass-filled nylon for machined structural and wear parts. Its long-term limit of 104 °C in air and its water uptake differ between the datasheets, so the test conditions should be checked before design.
