GC–SCGC joint venture:
what PE/PP buyers should know
Two of Thailand's largest petrochemical producers are studying a combination of their domestic olefins and PE/PP businesses into a single joint venture. Nothing is final and regulators still have to review it, but converters should understand the picture and plan for it now.
Published 22 Oct 2026 · Information as of publication · Marketing, Advanced Chem Solutions Co., Ltd.
What the deal is
PTT Global Chemical (GC) and SCG Chemicals (SCGC) signed a non-binding memorandum of understanding on 29 April 2026 to study a joint venture covering their olefins and polyolefins businesses in Thailand.
- Scope
- Both companies' Thai olefins crackers and PE and PP plants, plus related joint-venture holdings
- Combined size
- Over 7 million t/yr of olefins · over 6 million t/yr of PE+PP
- Proposed structure
- GC as major shareholder, SCGC with a significant stake; exact split not yet disclosed
Why it is happening
The global petrochemical industry is in oversupply after large new plants started up in China and the Middle East, and the spread between feedstock and polymer prices has stayed thin. Combining assets gives more scale, removes duplicated costs and adds flexibility in feedstock choice (ethane, propane, naphtha), helping domestic producers compete regionally. For the feedstock background, see crude oil, gas and plastic resin costs.
Timeline to watch
| When | Step |
|---|---|
| 29 Apr 2026 | Non-binding MoU signed |
| Q3 2026 | Confirmatory due diligence |
| Oct 2026 | Target to agree shareholding, transaction steps and synergies |
| Next | Filing with the Trade Competition Commission (TCCT) and board approvals |
| Within about a year | Target to establish the joint venture, subject to approvals |
What it could mean for resin buyers
The real effect depends on the final terms and on any TCCT conditions. Treat the table below as things to watch, not confirmed outcomes.
| Area | What could change | What converters can do |
|---|---|---|
| Supply continuity | Jointly run plants may cover maintenance shutdowns better | Confirm delivery plans around turnarounds with your supplier |
| Grade portfolio | Some grades may be merged, renamed or moved to another line | Ask about grade plans early; prepare re-qualification of alternatives |
| Pricing | Still linked to global markets and regional import prices | Track regional prices alongside domestic offers instead of guessing from market structure |
| Commercial terms | Ordering systems, contracts and distribution channels may change during integration | Reconfirm contacts, payment terms and lead times periodically |
| Technical service | Combined R&D may develop more high-value grades over time | Keep technical contacts up to date |
| Masterbatch and additives | If your grade changes, its MFI or built-in additive package may differ | Trial your formulation on the new grade before switching production |
The last point is easy to miss. Grades with similar names can carry different MFI, nucleating agents, slip or antistatic additives, so colour, clarity, shrinkage and cycle time can shift even with the same masterbatch. How to compare grades on a TDS is covered in polymer basics and reading a TDS.
Converter checklist
- List every resin grade you run, with alternatives you have already qualified
- Assess single-source exposure and keep a qualified back-up source
- Review supply contracts: term, price formula and what happens if a product changes
- Plan stock to cover your supplier's system transition
- Prepare masterbatch and additive trials in case a grade changes
- Follow official company announcements and the TCCT decision

Frequently asked questions
Is the GC–SCGC joint venture final?
No. As of 22 October 2026 the companies are in confirmatory due diligence. The deal still needs clearance from Thailand's Trade Competition Commission (TCCT) and internal approvals at both companies.
Will PE and PP prices in Thailand rise because of the deal?
It is too early to say. Thai resin prices still follow global markets and regional import prices, driven mainly by supply, demand and feedstock costs. Track regional prices alongside domestic offers.
What should plastics converters do now?
Nothing needs to change today. List the resin grades you use, identify qualified alternatives, review supply contracts, and plan masterbatch and additive trials in case a grade changes.
Who decides whether the deal affects competition?
Thailand's Trade Competition Commission (TCCT). It can clear the deal unconditionally, clear it with conditions, or block it.
