Who owns SCG ICO Polymers Company Limited
One company in the researched set discloses a stake in SCG ICO Polymers Company Limited, none of it sized by anyone who discloses it. SCG ICO Polymers Company Limited is private, so no 13F reports it: a 13F covers exchange listed positions only. These figures exist because each holder disclosed the stake in its own filings.

SCG ICO Polymers, now trading as SCGC ICO Polymers, makes rotational moulding powders and rotomoulding compound granules in Thailand and sells them across the Asia Pacific region. It was formed on 6 September 2013 by SCG Chemicals, the petrochemical arm of Thailand's Siam Cement Group, and A. Schulman Plastics Malaysia, the specialty compounding business later absorbed into LyondellBasell, with SCG supplying polyolefin feedstock and regional distribution and the compounding partner supplying rotomoulding formulation technology. Its grades are used to mould large hollow plastic items such as water storage tanks, outdoor furniture and kayaks. The company is registered in Bangkok and sits inside SCG Chemicals' downstream polyolefins business.

SCG ICO Polymers Company Limited files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from A. Schulman, Inc. Form 10-K for fiscal 2015 (SEC), SCG Chemicals company structure and LyondellBasell Industries Form 10-K Exhibit 21, list of subsidiaries and joint ventures as of 31 December 2025. The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- LyondellBasell Industries N.V.. Exhibit 21.1 to the FY2025 10-K (filed 20 Feb 2026) states that LyondellBasell Advanced Polyolefins (Malaysia) Sdn. Bhd. owns a 13% interest in SCG ICO Polymers Company Limited. This is a 13 percent ownership interest, written here as the number 13, not as a fraction of 100. LyondellBasell's balance sheet carries a single combined 'Equity investments' line ($3,963 million at 31 Dec 2025 per the 10-K; $3,875 million at 30 Jun 2026 per the most recent 10-Q) covering all equity-method investees together, so no individual carrying value is disclosed for this venture: value_usd is null. sourcesource 2
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of SCG ICO Polymers Company Limited where a holder stated one, and are missing where no holder did.
