The clearest split this week was between the recycled and virgin complexes rather than between regions. In the US, recycled PET, HDPE and LDPE all held or extended gains for a second consecutive week, a run that has now outlasted the seasonal support most buyers expected to fade by mid-September. Virgin markets, by contrast, diverged sharply by region: Asian PP came under pressure as Brent crude fell roughly $6/barrel over the week, compounded by pre-holiday inventory clearing, while European PP copolymer buyers began accepting increases ahead of anticipated October hikes. Brazil, ordinarily an active swing market for recycled PET, saw market participants report little to no trading activity as the country's Oct. 4 first-round election approached, compounding an already uncertain outlook tied to Braskem's unresolved debt reorganization.

Three Factors Shaping This Week's Market

1. US recycled grades are the one segment still firming across the board Recycled PET, HDPE and LDPE in the US either extended or held gains for a second straight week, standing apart from a softer Asian virgin complex. Buyers who assumed the multi-week firming was seasonal and due to fade may want to re-test that assumption, since the run has continued past the point most forecasts expected a pullback.

2. A sharp Brent drop split the virgin market by region, not by direction Brent crude fell roughly $6/barrel over the week, pulling Asian virgin PP prices down and cushioned only partly by tight regional supply and producers clearing inventory ahead of China's October Golden Week holiday. Europe moved the opposite way: PP copolymer spot prices rose as buyer sentiment shifted, with converters accepting roughly €50/mt increases ahead of hikes anticipated for October, and European PVC firmed further on speculative buying tied to record European gas prices. The same crude move produced firming in one region and softening in another, which is a reminder that a single "virgin PP" reference price does not travel across regions this week.

3. Brazil's election calendar and Braskem's restructuring are compounding, not separate, sources of caution Brazil's national elections (first round Oct. 4, a potential runoff Oct. 25) left market participants reporting little to no trading activity this week, even as Brazilian recycled PET extended its own rally for a second straight week — a sign that the pause is procedural rather than a demand problem. Braskem's extrajudicial reorganization, covering roughly $10.9 billion in debt under a 90-day court-ordered protection period set to expire around Nov. 22, remains unresolved and continues to leave the region's largest integrated PE/PP producer's medium-term supply position an open question for buyers planning Q4 and Q1 cover.

Key Grade Performance: rPET, rHDPE and rLDPE

rPET Market — US firms modestly, Brazil extends a second week of gains US recycled PET prices trended modestly higher overall this week: bales were largely flat while flakes and pellets firmed broadly. Brazil extended its across-the-board rally for a second straight week, notable given the market's otherwise quiet backdrop ahead of the Oct. 4 election. Why it matters: a Brazilian rPET quote holding through election-week inactivity elsewhere in the market suggests the gain is demand-driven rather than a byproduct of thin trading. Buyers may still want to confirm current levels hold once election-week liquidity normalizes.

rHDPE Market — mixed-color bales show the clearest tightening Natural HDPE grades edged up only slightly, but mixed-color bales showed the clearest tightening trend of the week, extending gains for a second consecutive week. Why it matters: the split between natural and mixed-color performance means a single rHDPE reference doesn't describe both streams; a mixed-color increase should not be read across to natural-grade material.

rLDPE Market — last week's gains hold rather than extend Recycled LDPE consolidated at last week's sharp gains rather than moving further, a pause that lines up with sellers positioning ahead of the EU's November 2026 ban on plastic waste exports to non-OECD countries rather than a change in underlying demand. Why it matters: a flat week after a sharp run is not the same as a reversal. Buyers evaluating rLDPE cover may want to treat this as a consolidation point to watch rather than a signal that the firming trend has ended.

Key Company, Trade and Regulatory Updates

Brazil — national elections freeze polymer market activity. The first round of Brazil's national elections is set for Oct. 4, with a potential runoff on Oct. 25. Market participants reported little to no trading activity this week as the country awaits the results.

Braskem — extrajudicial reorganization remains unresolved. Braskem's court-backed extrajudicial reorganization, covering roughly $10.9 billion in debt, is running under a 90-day protection period set to expire around Nov. 22, with creditors given an Oct. 9 marker; the case continues without a confirmed resolution, leaving the outlook for the region's largest integrated PE/PP producer clouded for buyers planning forward cover.

China — PVC exports jump as imports collapse, reinforcing net-exporter shift. August customs data showed China's PVC exports surging month over month while imports fell just as sharply, reinforcing the country's continued shift toward a large net PVC exporter position. (Exact tonnage and percentage figures are being confirmed against official customs data before this line is finalized for publication.)

Market Takeaway

This week's clearest signal was the divergence between the recycled and virgin complexes rather than any single regional story. US recycled PET, HDPE and LDPE continued a firming run that has now outlasted its expected seasonal support, while Asian virgin PP softened on a sharp Brent pullback and pre-Golden Week inventory clearing, and European PP moved the opposite way on a genuine demand recovery. Brazil remains the market to watch most closely: its election calendar has paused trading activity even as its recycled PET market keeps rallying, and Braskem's unresolved restructuring leaves an open question over the region's PE/PP supply base heading into Q4. Regenport will continue monitoring both the US recycled firming trend and the Brazil/Braskem situation as the picture develops.

Frequently Asked Questions

Why did US recycled polymer prices keep rising while Asian virgin PP fell this week? The two markets are responding to different drivers: US recycled PET, HDPE and LDPE extended a multi-week firming trend tied to underlying demand, while Asian virgin PP fell largely because Brent crude dropped roughly $6/barrel over the week and producers cleared inventory ahead of China's October Golden Week holiday.

Why is Brazil's polymer market inactive this week? Brazil's first-round national election is scheduled for Oct. 4, 2026, with a potential runoff on Oct. 25. Market participants reported little trading activity as the country awaits the results, even though Brazilian recycled PET prices extended their own rally through the pause.
