How it compares
These rows are for different grades and test conditions, so they are examples and not a ranking. The unfilled TECATRON natural and the 40 % glass grades cannot be compared directly for stiffness or strength.
The same measurements for each material, so you can compare them. Each row names the key condition under the value; the full conditions and methods are in the numbered notes under Technical details. Other materials are shown beside it; each was measured under its own conditions, so open its page before comparing closely. Compare every grade in the family.

Why choose it, and why not
Good for
- Glass-filled electrical and fluid-handling parts: 265 °C deflection at 1.8 MPa (Fortron 1140L4 and Ryton R-4-200BL).
- Low outgassing applications: 0.09 % TML and 0.00 % CVCM for Ryton PPS (Gund bulletin).
Watch out for
- Ductility: elongation at break is 1.5 % (Ryton R-4-200BL) and 1.7 % (Fortron 1140L4), so these grades are brittle compared with tougher plastics.
- Long-term heat: the unfilled TECATRON natural is rated at 338 °F long term, below the melting temperature of 536 °F.
- Atomic oxygen in orbit: no erosion yield for PPS was found in the NASA sources read, so the orbital behaviour is not known from this profile.
PPS is a stiff, heat-resistant, electrically insulating thermoplastic. The 40 % glass grades read have a 265 °C deflection temperature at 1.8 MPa, and the Ryton PPS outgassing table gives 0.09 % total mass loss. Its ductility is low, at 1.5 % to 2.5 % elongation, and no sourced atomic-oxygen or UV data was found.

Corrosion and compatibility
What happens when it meets other materials and environments.
| Environment | Concern | What happens |
|---|---|---|
| Chemical exposure at room temperature | not rated | PPS is described as having very good chemical resistance, and the 40 % glass grade as having excellent chemical resistance.1 |
| Long-term heat in service | not rated | Ensinger gives a long-term service temperature of 338 °F and an intermittent limit of 500 °F for TECATRON natural.2 |
| Heat in the form of prolonged exposure above 698 °F | not rated | Prolonged exposure above 698 °F causes thermal decomposition.3 |
| # | Environment | Details | Test conditions |
|---|---|---|---|
| 1 | Chemical exposure at room temperature | Ensinger lists very good chemical resistance among the main features of TECATRON natural. Celanese states that Fortron 1140L4 has excellent heat and chemical resistance and is used for automotive heaters, pumps, valves and fuel rails. No solvent, acid or base test with a number was read. | basis manufacturer product descriptions, no test condition printed |
| 2 | Long-term heat in service | The 338 °F long-term figure and the 500 °F intermittent figure are both printed in the thermal properties table. The sheet gives no test standard for these rows. | basis manufacturer nominal values, unfilled grade for the service temperature |

Risks and side effects
Hazards to people, what happens when a cell overheats, and how the material is handled and stored.
For people
The product SDS prints no GHS classification, but gives handling rules for dust.
- Classification
- The Techtron HPV PPS SDS prints the GHS classification, signal word and hazard statements as None.
- Dust
- Fine dust can form an explosive mixture with air, so the SDS requires grounding and NFPA 484 and 654 measures.
If it fails
The failure route in these sources is prolonged heat above 698 °F.
- Decomposition
- The SDS gives carbon oxides, sulfur oxides, carbonyl sulfide and fluorine-containing gases as decomposition products.
Test details
The original wording and numbers from the sources, for readers who want them.
Failure risks
| Failure | Trigger and consequence |
|---|---|
| Thermal decomposition on prolonged heatingmoderate severity | Prolonged exposure above 698 °FGaseous decomposition products, including carbon oxides, sulfur oxides, carbonyl sulfide and fluorine-containing gases. |
Handling and storage
- Ground all transfer, blending and dust collection equipment, and follow NFPA 484 and NFPA 654 for combustible dust. Use local exhaust ventilation where dust may form.

summary: |
Polyphenylene sulfide (PPS) is a semicrystalline high-performance thermoplastic with the repeat unit [C6H4S]n. The unfilled Ensinger TECATRON natural has a density of 1.36 g/cm3 and a melting temperature of 536 °F, and a tensile strength at yield of 13700 psi. The 40 % glass-filled grades read are stiffer and hotter: Celanese Fortron 1140L4 has a melting temperature of 280 °C (ISO 11357-3) and a deflection temperature of 265 °C at 1.8 MPa (ASTM D648), and Syensqo Ryton R-4-200BL has a density of 1.68 g/cm3 and the same 265 °C deflection temperature. A Gund Company outgassing table lists Ryton PPS at 0.09 % total mass loss and 0.00 % CVCM. No atomic-oxygen erosion yield for PPS was found in the NASA sources read.

gaps:
- 'Atomic oxygen erosion yield for PPS: not found. The NASA-HDBK-6024 text read has no polyphenylene sulfide row, and the NASA TM read did not list PPS.'
- 'Outgassing from a PPS datasheet or NASA database entry: only the Gund bulletin row for Ryton was read. The NASA outgassing database was not reached.'
- 'Melting point of the Ryton R-4-200BL sheet: the sheet prints no melting point, and the Syensqo melting value was not read.'
- Techtron HPV SDS prints a melting point of 545-572 °F and a specific gravity of 1.43. Neither is used here because the SDS is for a fibre-reinforced product and not a datasheet value.
- 'Torelina A900 (Toray): a search snippet gave density, melting temperature and tensile strength, but the page could not be fetched, so none of its values are used. The Toray A670 R63 PlaBase page is an elastomer-modified grade and is not used.'
- Ensinger notched Izod row prints its unit as "ftlbsin", which is not a unit that can be checked, so the value is left out.
- Ensinger density and melting temperature rows print no test standard. The melting row has no norm either.
- 'Chemical resistance by solvent, acid or base with numbers: not found in the sources read. Qualitative statements only.'
- 'UV and sunlight ageing of PPS: no retention figure was read.'
- 'Radiation, thermal cycling and cryogenic data for PPS in space: none read.'
- 'Producer tonnages and country shares for PPS: not found. The producer list comes from a Wikipedia page with no figures.'
- 'Standard designations (UNS, EN, DIN, JIS, AISI, ASTM) for PPS as a material: none printed in the sources read. Only trade names are listed.'
- 'Non-canonical property names used: notched_izod_impact, oxygen_index, total_mass_loss, collected_volatile_condensable_materials, water_vapor_regained. Molding shrinkage (flow 0.20 to 0.30 %, Fortron 1140L4, ASTM D955) is not included because the name is not in the canon file.'
- Fortron 1140L4 tensile modulus at 23 °C (ISO 527-2, 14700 MPa) is in the sheet, but the sheet gives no temperature for that row, so it is not used.
- 'Volume resistivity of 1.0E+16 ohm·cm (Fortron 1140L4, ASTM D257 row; Ryton R-4-200BL, ASTM D257 row) is left out: the sheets print 1.0E+16 and the value could not be matched to the source text by verify-values.'

note: 'Values were read by an AI assistant on 2026-10-25 from the pages named in each entry. Celanese and Syensqo values are from UL Prospector copies of their technical data sheets, not the manufacturer sites. The Ryton row values are typical, and no test standard is printed for some rows. The Ensinger values are for an unfilled grade. The outgassing values come from a supplier bulletin that cites NASA data and carries a misprinted test temperature, which is not copied here. Unreachable: Knowde (Toray Torelina A900), PubChem, Ensinger datasheet PDF, Celanese own site.'
story:
recipe:
line: PPS is made by reacting sodium sulfide with 1,4-dichlorobenzene in N-methyl-2-pyrrolidone as the solvent. The repeat unit is [C6H4S]n, a benzene ring with a sulfur link between each ring.
parts:
- name: Carbon
symbol: C
role: Six carbons in each benzene ring, from 1,4-dichlorobenzene.
share_note: standard atomic weight [12.0096, 12.0116]
- name: Hydrogen
symbol: H
role: Four aromatic hydrogens per repeat unit.
share_note: standard atomic weight [1.007 84, 1.008 11]
- name: Sulfur
symbol: S
role: One sulfide link per repeat unit, from sodium sulfide.
share_note: standard atomic weight [32.059, 32.076]
risk_groups:
- title: For people
lead: The product SDS prints no GHS classification, but gives handling rules for dust.
level: 1
verdict: Not classified in the SDS read
points:
- label: Classification
line: The Techtron HPV PPS SDS prints the GHS classification, signal word and hazard statements as None.
- label: Dust
line: Fine dust can form an explosive mixture with air, so the SDS requires grounding and NFPA 484 and 654 measures.
- title: If it fails
lead: The failure route in these sources is prolonged heat above 698 °F.
points:
- label: Decomposition
line: The SDS gives carbon oxides, sulfur oxides, carbonyl sulfide and fluorine-containing gases as decomposition products.
why: PPS is a semicrystalline high-performance thermoplastic. The 40 % glass-filled grades read have a melting temperature of 280 °C (Fortron 1140L4) and a 265 °C deflection temperature at 1.8 MPa (Fortron 1140L4 and Ryton R-4-200BL). The unfilled TECATRON natural has a density of 1.36 g/cm3 and a 13700 psi tensile strength at yield.
can_do:
- label: Stay stiff when hot
value: 265 °C deflection at 1.8 MPa
benchmark: heat_deflection_temperature
line: Fortron 1140L4 and Ryton R-4-200BL both print 265 °C at 1.8 MPa, unannealed, under ASTM D648.
- label: Low outgassing
value: 0.09 % TML
benchmark: total_mass_loss
line: The Gund table lists Ryton PPS at 0.09 % total mass loss and 0.00 % CVCM.
compare: These rows are for different grades and test conditions, so they are examples and not a ranking. The unfilled TECATRON natural and the 40 % glass grades cannot be compared directly for stiffness or strength.
compare_rows:
- scope: material
label: Density
benchmark: density
- scope: material
label: Heat deflection temperature
benchmark: heat_deflection_temperature
- scope: material
label: Moisture absorption
benchmark: moisture_absorption
handling:
- Specify the grade, since unfilled and 40 % glass-filled PPS differ in strength, stiffness and heat deflection.
- Ground transfer and dust-collection equipment and follow the NFPA dust rules when handling powder or fine dust.
- Treat the values as typical nominal values, as the sources state.
good_for:
- 'Glass-filled electrical and fluid-handling parts: 265 °C deflection at 1.8 MPa (Fortron 1140L4 and Ryton R-4-200BL).'
- 'Low outgassing applications: 0.09 % TML and 0.00 % CVCM for Ryton PPS (Gund bulletin).'
watch_out:
- 'Ductility: elongation at break is 1.5 % (Ryton R-4-200BL) and 1.7 % (Fortron 1140L4), so these grades are brittle compared with tougher plastics.'
- 'Long-term heat: the unfilled TECATRON natural is rated at 338 °F long term, below the melting temperature of 536 °F.'
- 'Atomic oxygen in orbit: no erosion yield for PPS was found in the NASA sources read, so the orbital behaviour is not known from this profile.'
verdict: PPS is a stiff, heat-resistant, electrically insulating thermoplastic. The 40 % glass grades read have a 265 °C deflection temperature at 1.8 MPa, and the Ryton PPS outgassing table gives 0.09 % total mass loss. Its ductility is low, at 1.5 % to 2.5 % elongation, and no sourced atomic-oxygen or UV data was found.
