Compilation Date: 2026-09-14
Compilation Notes: This statement summarizes the unresolved gaps in each of the 118 articles of the 'International Major Manufacturer Sub-Brand Series,' including but not limited to:
(1) Differences in market share/production capacity rankings across different data sources, without making absolute ranking determinations;
(2) Niche categories with fewer than three leading companies are presented by tier rather than strictly ranking the top three;
(3) Some categories have overlapping product lines (e.g., ULDPE/mLLDPE/POP, COC/COP), with data sources aggregated;
(4) Involving corporate mergers and reorganizations (e.g., Solvay→Syensqo, DuPont→Celanese, DSM/Lanxess→Envalior, etc.), brand ownership has been marked, but market classification is still in transition.
The following lists the gaps in each article by serial number. Articles without clear gaps are marked as 'None.'
The figures differ slightly depending on the research report—some are based on production capacity, others on market share, and the second and third places often swap back and forth.
Chimei usually ranks ahead in terms of production capacity, while LG Chem is catching up closely in terms of market share and high-end grades. Which of the two takes the lead depends on which report you refer to.
Under different research report standards, the third place Teijin and Mitsubishi Engineering Plastics occasionally switch positions
Under different research report criteria, DOMO and Envalior rank alternately high and low in the category of engineering modified pellets.

According to market share standards, most of these companies are between 6% and 16%, with different institutions having discrepancies in their statistical criteria.
According to some institutions, Shin-Etsu accounts for about 12% to 14% globally, Formosa Plastics about 12%, and Westlake Chemical about 6% to 9%, with slight differences depending on the data source.
Chimei's market share fluctuates between 10% and 22%, with rankings differing across various data sources.
None
The market shares of these three companies fluctuate around 16%, 13%, and 11%, according to Dataintelo.
Differences exist among sources due to varying standards of capacity/share, presented by tier, without strictly ranking positions.
The market share data from different sources conflict; some say Dow is close to 20%, while others say Zhongyuan is 15% to 18—the differences in standards have caused the industry to argue for several years, speaking in terms of tiers.
None
The total market share of the top four companies exceeds 90%, indicating a very high concentration.
When there is a discrepancy in data sources, looking by tier, BASF and Chi Mei are also in this tier.
There is confusion between AES and ASA in terms of specifications from different sources. This article organizes the top three tiers according to the AES specialized rubber system (EPDM), without rigidly ranking them.
Different sources have different data standards; Polyscope's market share has been reported by some as just over 20% and by others as over 30%. In terms of tiers, exact numbers are not strictly assigned.
None
None
DOMO's DOMAMID long-chain nylon is also in the same tier, without a fixed ranking
Different sources confuse the calibers of PA612 and PA12. This article sorts out the top three tiers according to the PA612 route, without ranking them rigidly.

The three companies have consistently ranked among the top three globally in terms of production capacity. There are differences in the share values from different sources, and they are presented by tiers.
The market shares of each company vary across different subcategories of SBS and SEBS, ranked by tier.
None
None
The market share fluctuates around 16%, 13%, and 11%, with SABIC and Mitsui Chemicals also in the same tier.
There are differences in the numerical shares from different sources. This article sorts out the top three tiers according to technology and brand influence, without strictly ranking them.
None
None
None
The above is the dedicated material tier for pipelines, not the ranking of all PE production capacities; where there are discrepancies between data sources, we explain according to tiers without strictly ranking positions.
ULDPE is often stacked together with POP and mLLDPE on the product line. There are slight discrepancies in the data sources, and it is more prudent to look at them by tier.
MVLDPE and mLLDPE are produced on the same metallocene production line, with different density grades. Data sources often combine them in statistics, categorizing them by tiers.
There are discrepancies in rankings across different data sources—some reports list SK Chemicals as having leading capacity (around 40%), while others rank Dow at the top (20-30%). According to tiers, they are not strictly ranked.
EEA, EVA, and EAA are often discussed together in the industry chain. There are discrepancies in the ranking of data sources, and their positions should not be forcibly arranged when talking by tiers.
EMA is sometimes counted together with EMAA in different reports, and there are discrepancies in the ranking of data sources. When discussing tiers, no strict ranking is applied.
EMMA pure-grade suppliers are few and far between, making it a typical oligopolistic category.
None
None
Coca-Cola's global market share is between 30% and 40% (there are differences depending on the measurement caliber)
Borlink's ultra-high pressure grade secondary brands generally do not flow into the medium and low-pressure markets; what circulates to small and medium factories is mainly the medium-pressure grade transition material.
Raw material grade (extrusion/molding) and fiber grade are two separate routes; don’t mix them up.
PMP is almost entirely supported by Mitsui Chemicals alone, accounting for more than 70% of the global share, without necessarily being in the top three.
The bulk of global CPE production capacity is in China, while the top foreign tier is ranked according to technological benchmarks.
Lubrizol accounts for about 20% to 30% of the global CPVC resin market, depending on the caliber.
For PA1010 abroad, only EMS, Evonik, and Arkema are dominating.
None
Lavanta from Syensqo, a subsidiary of Solvay, is also on this plate.
Arkema Pebax accounts for about 20% to 40% of the global PEBA market (different institutions have varying figures)
None
None
None
None
OBC is almost a monopoly, with the main player being Dow INFUSE, while the rest are mostly followers or supporting products and should not be forcibly ranked in the top three.
None
The SBR industry is very fragmented, with no single company dominating the market. The top three foreign manufacturers globally together account for just over 20% of the market share.
None
LCBR is a niche category, not many foreign major companies are involved, and based on the actual ranking, it doesn't firmly place in the top three.
None
SOE is so niche that it's almost a monopoly: Asahi Kasei S.O.E. is the flagship, but it doesn't solidly rank in the top three when listed by tier.
The numbers vary slightly between reports, but the top three positions have basically remained unchanged.
Later, there were also follow-ups from Nordic chemical companies like Borflow, but they were half a step behind in terms of circulation volume and certification accumulation.
The three companies together account for 80-90% of the global PEEK production capacity, a typical oligopoly structure.
In the first tier of PEI, SABIC ULTEM dominates, while the second tier consists of various manufacturers that use its resin for downstream modification. The oligopolistic categories are listed according to the actual tiers, not forcibly rounded up to the top three.
Fortron linear PPS from Wu Yu Chemistry Kureha is another important source of supply
None
Sumitomo Chemical's sub-brand is relatively niche, with common fluctuations in liquidity and color, small quantities, and limited channels.
Outside of the three companies, there are quite a few scattered modified materials and OEM materials on the market, which are not within the discussion scope of the original granules from major foreign manufacturers.
PAR is a typical niche category, with only a few leading foreign companies globally. It is written according to the actual tiers rather than being rigidly ranked.
For PARA niche materials, only these two original manufacturers are the strongest; the rest are mostly modified blends, not original raw particles from the factory.
Outside of the three companies, Toray Siveras, Kuraray, and others are also participants, and domestic materials are catching up.
POK is an almost oligopolistic niche category, with major global foreign players listed according to their actual tier.
The share is based on the scope of third-party reports, and there are slight differences between different data sources.
Stanyl accounts for around 85% of the global PA46 production capacity, forming an oligopoly.
PA4T pure resin mass production enterprises are relatively concentrated, and according to the actual tier, they do not strictly rank in the top three of the same level.
Share/capacity is according to third-party reports, and there are slight differences between different data sources.
PA9T pure resin mass production companies are relatively concentrated, with the actual tiers not strictly ranking the top three; modified products differ from the original manufacturer's secondary brand.
Domestic manufacturers (such as Kingfa Technology) are not included in the top three foreign companies as required; market share is according to third-party reports, and there may be slight discrepancies between different data sources.
None
COP is more niche than COC, and globally, the companies that can stably mass-produce high-end COP are basically just a few in Japan.
The large-scale commercial production of SPS base material is almost monopolized globally by Japan's Idemitsu Kosan; do not forcibly list three foreign companies, write according to the actual hierarchy.
None
None
There are differences in the estimates of market share for 3M and Solvay in industry reports; some sources show 3M higher, while others show Solvay higher.
The figures in several reports vary slightly, but the conclusion that the top three oligopolies account for about 75% to 80% matches up.
There may be discrepancies in the ranking of resin diameter and membrane diameter, and data disagreements exist.
ECTFE is a standard oligopoly category, with Solvay Halar accounting for about 68% of the global market, not strictly ranking in the top three.
EFEP is so niche that almost no one is doing it; Daikin is the main commercial manufacturer, not strictly ranked in the top three.
Different data sources estimate NatureWorks' share differently (approximately 28.5% to 35%)
None
None
PBSA is a segmented pool; there are quite a few domestic players, but this only refers to non-mainland factions.
The PBST category itself is niche, with limited overseas mass production scale. Writing it by tier is more practical than strictly ranking them.
None
None
The pool of major foreign manufacturers of PSM/starch-based materials is not very large, when viewed by tier.
ColaLi PVA optical film raw materials account for 70% to 80% of the global market, and estimates of total production capacity share vary between different data sources.
Eastman about 35%, Cellulose about 12% market share, cross-check
Eastman has approximately a 45%-50% market share, with slight variations depending on the data source.
Eastman, Celanese, Daicel, Mitsubishi Chemical, Solvay, the top five account for about 58%-62% of production capacity
Sumitomo Bakelite approximately 18.4%, Hansen approximately 16.2% share caliber
DAP is a very niche category with a high concentration, and Dasa Lu's electronic-grade DAP ≥99.9% has long dominated imports.
