Propellant Stabilisers

A bounded source-linked profile of European diphenylamine, ethyl-centralite and methyl-centralite production, grade and qualification boundaries, disclosed capacity states, import signals and selected downstream propellant use.

Which exact European sites currently make diphenylamine, ethyl centralite or methyl centralite for propellant-relevant supply, at what disclosed product scope, and what evidence permits a source or stabiliser change in a qualified formulation?
SB-SMP-0009Version 0.1.0MOVING CURRENTEvidence cutoff 2026-08-31EU-27 + United Kingdom + Norway + Switzerland + Serbia + Türkiye

Current centralite production is site-resolved; current European propellant-grade DPA supply is not.

As of 2026-08-31
Comparable current stabiliser capacityUNKNOWN

Synthesia explicitly offers ethyl and methyl centralite from its Semtín production site. Duslo's Šaľa DPA asset is exact, but the latest retained inspection found the entire plant shut after an October 2024 fire.

Current merchant-oriented qualified stabiliser capacityUNKNOWN

Synthesia's centralite pages and sales channel are current merchant evidence. Duslo's catalogue and dispatch evidence do not close post-fire operation or propellant-grade acceptance; LANXESS supplies a current non-European DPA signal.

Uncommitted qualified stabiliser supplyUNKNOWN

The retained evidence does not join current output, supplier grade, formulation acceptance, commitments, inventory and allocatable quantity.

Capacity composition unavailable UNKNOWN

Comparable current annual European propellant-stabiliser capacity. The current centralite site discloses no product-specific annual capacity, and Duslo's permitted DPA ceiling cannot be treated as current output from a plant shut at its latest retained inspection.

Inference boundary. The current centralite site discloses no product-specific annual capacity, and Duslo's permitted DPA ceiling cannot be treated as current output from a plant shut at its latest retained inspection. No numeric headline sum is emitted. The Duslo 24,500 t/y figure is a permitted or projected facility ceiling, not current production, actual output, defence allocation or propellant-qualified supply.
01 · Material role

The strategic object is an accepted stabiliser source inside an accepted formulation.

Chemical identity, supplier grade, formulation use and application qualification remain separate.

  1. 01 · MaterialDPA, ethyl centralite or methyl centraliteEach chemical and supplier grade remains a distinct material object.
  2. 02 · FormulationSelected nitrocellulose-based propellantA named stabiliser can be one controlled ingredient in a bounded formulation; the profile publishes no recipe.
  3. 03 · Stability evidenceStabiliser depletion and compatibility testingStability surveillance is formulation- and test-specific rather than a universal shelf-life conversion.
  4. 04 · QualificationManufacturer, location, source and application acceptanceA source or manufacturing-location change can require renewed material and end-use qualification.
  5. 05 · Qualified outputAccepted propellant or ammunition configurationChemical availability does not by itself establish acceptance in a named charge, cartridge or weapon.

Source- and application-accepted stabiliser

These stabilisers can be formulation-controlled inputs to nitrocellulose-based propellants, where stabiliser depletion is one element of stability surveillance; the three chemicals, their grades, sources and accepted applications are not interchangeable.

Chemical identity or generic gunpowder-use statement

A chemical name, a supplier product sheet, a gunpowder-use statement, a formulation assay, a material source and acceptance in a particular propellant or ammunition configuration are different evidence states. The profile does not publish formulations, recipes or process conditions.

Profile scopeEU-27 + United Kingdom + Norway + Switzerland + Serbia + Türkiye. Exclusions: Russia; Belarus; A company catalogue or address presented as an active propellant-grade production line without a product-site and operating-state join; A permitted or projected facility ceiling presented as current operating capacity, actual output or propellant-grade capacity; A current non-European product lane or tariff suspension presented as quantified European import dependence; Diphenylamine, ethyl centralite and methyl centralite presented as interchangeable substitutes; A product's packaged-storage statement presented as propellant, ammunition or weapon shelf life; A stabiliser-to-propellant relationship promoted to a named weapon, 155 mm charge or supplier join without exact evidence descent; Synthesis recipes, process conditions, formulation percentages or operational production instructions. This is a bounded public-source map, not a complete producer census, accepted-source list, capacity balance, import balance or formulation register. Missing public evidence is retained as unknown rather than absence, zero supply or scarcity.

Semtín is current and product-specific; Šaľa is exact but inactive at its last evidenced inspection.

    Capacity reading rule The current centralite site discloses no product-specific annual capacity, and Duslo's permitted DPA ceiling cannot be treated as current output from a plant shut at its latest retained inspection. Synthesia discloses no product-specific annual centralite capacity. Duslo's 24,500 t/y DPA facility figure remains a permitted or projected ceiling attached to an asset that was shut at the latest retained inspection.
    03 · Market structure

    Merchant pages and import signals do not disclose qualified allocation.

    Current product availability, imported supply, captive production and accepted alternates remain different questions.

    Current merchant-oriented qualified stabiliser capacityUNKNOWN

    Synthesia exposes current external product and sales channels for both centralites. A current non-European DPA merchant lane and an EU tariff suspension do not quantify Europe's source mix, qualified imports or available headroom.

    Current integrated or programme-dedicated stabiliser capacityUNKNOWN

    The retained evidence does not establish whether downstream European military propellant producers synthesize these stabilisers internally, buy them from named suppliers or hold qualified alternate sources.

    Current strategic finding · INFERRED

    The bounded evidence resolves one current European site for ethyl and methyl centralite at Semtín. It also resolves Duslo's Šaľa DPA asset but not current operation or propellant-grade output after the plant was found shut in July 2025. Comparable capacity, import dependence and uncommitted qualified supply remain unknown.

    • The producer search is bounded rather than exhaustive.
    • One site offering two products is not two independent sources.
    • Unknown captive production, inventory and qualified imports are not treated as absent.
    • Could reverse: Authoritative evidence of post-fire Duslo restart and current DPA output
    • Could reverse: A verified additional current European production site for any of the three stabilisers
    • Could reverse: Comparable current output and accepted-grade data by site
    Nearest disclosed intervention surfaceThe nearest decision-relevant work is to verify Duslo's post-fire operating and grade state, close Synthesia's product-specific output and allocation, and obtain application-level accepted-source matrices. No bounded public expansion lane is mature enough to promote.
    04 · Expansion pipeline

    No bounded expansion lane is promoted in v0.1.

    A future restart or investment requires its own site, product, commissioning and acceptance evidence.

      Conversion and planned records

      Pipeline boundary No bounded current expansion project is promoted. Absence of a retained project is not evidence that no investment, restart or qualification activity exists.
      05 · Dependencies & bottlenecks

      Source control and application qualification prevent chemistry-only substitution.

      The evidence supports friction mechanisms without a universal switch duration or scarcity conclusion.

      Revision history

      DateVersionChange
      2026-08-310.1.0Initial moving-current Propellant Stabilisers research alpha: one exact current European site for ethyl and methyl centralite, one exact DPA asset retained at its last evidenced shut state, a non-current regulatory DPA ceiling, explicit import and capacity unknowns, and application-specific qualification without interchangeability or downstream weapon joins.
      Publication boundary. SB-SMP-0009 identifies one analytical family publication. Diphenylamine, ethyl centralite and methyl centralite remain three separate Defence Industrial Foundations material nodes and are not collapsed into a new canonical material identity or added to the released Industrial Network. The public Industrial Network remains industrial-network-api-v0.1 over released industrial-network-v0.2.
