Polyvinyl chloride production across South America in 2026 is estimated at approximately 3.8 to 4.5 million tonnes, positioning the region as a mid-scale, demand-anchored PVC producer with limited export leverage compared with the Middle East or North America. Production is primarily oriented toward domestic and regional consumption, closely linked to construction, water infrastructure and industrial development cycles.
Output levels are governed by ethylene availability, chlorine integration efficiency, plant utilisation rates, energy costs and downstream construction demand. Countries with integrated petrochemical and chlor-alkali infrastructure account for the majority of capacity, while smaller markets rely on imports to balance supply.
From a production-cost perspective, South American PVC economics are influenced by ethylene sourcing (domestic vs imported), electricity prices for chlor-alkali units, plant scale efficiency and logistics costs. Capacity evolution reflects incremental debottlenecking, maintenance-driven reliability improvements and selective downstream integration rather than large greenfield expansion.
Suspension PVC dominates South American production due to its central role in housing, water distribution and sanitation infrastructure. Production systems prioritise volume consistency, mechanical performance and compliance with construction standards.
Emulsion and compound grades represent a smaller but strategically important share, supporting industrial diversification and higher-value downstream applications.
South American PVC production is almost entirely ethylene-based, with chlorine sourced from membrane-cell or diaphragm-cell chlor-alkali plants depending on asset age. Process optimisation focuses on energy efficiency, chlorine balance stability and operational reliability.
From a production standpoint, managing electricity costs and chlorine co-product markets is central to sustaining competitive operating rates.
Construction and water infrastructure dominate PVC consumption, driven by urbanisation, public works investment and housing demand. These sectors provide volume stability but are sensitive to economic cycles and government spending.
Industrial and consumer applications add diversification but do not define baseload production capacity.
The largest PVC producer in the region, supported by integrated petrochemical, chlor-alkali and conversion infrastructure serving construction and infrastructure markets.
PVC production linked to domestic ethylene supply and construction demand, with output primarily serving the local market.
Smaller-scale production and compounding operations supporting regional construction and industrial demand.
South America’s PVC supply chain starts with ethylene and salt procurement, followed by chlor-alkali production, EDC/VCM synthesis, polymerisation and regional distribution. Trade flows are primarily intra-regional, with imports from North America and Asia used to balance supply during demand upswings.
Key cost drivers include ethylene pricing, electricity costs, chlorine co-product economics, labour intensity and logistics. Pricing formation reflects feedstock economics and regional supply-demand balance rather than global PVC spot markets.
South America’s PVC ecosystem includes petrochemical producers, chlor-alkali operators, compounders, converters, construction firms and public infrastructure agencies. The ecosystem is characterised by demand-led production, moderate scale and sensitivity to macroeconomic conditions.
Strategic priorities focus on improving energy efficiency, ensuring chlorine balance stability, expanding downstream compounding, maintaining asset reliability and aligning PVC output with long-term infrastructure development plans.
PVC production across South America in 2026 is estimated at approximately 3.8 to 4.5 million tonnes, largely serving domestic construction and infrastructure markets.
Key cost drivers include ethylene sourcing, electricity prices for chlor-alkali units, plant efficiency, labour costs and logistics expenses.
Suspension PVC (S-PVC) dominates due to its extensive use in pipes, fittings and construction materials, while emulsion and compound grades serve smaller specialty segments.
Imports play a balancing role, particularly during periods of strong construction demand or local plant downtime.
Constraints include capital intensity, energy cost volatility, regulatory complexity, infrastructure limitations and the focus on optimisation rather than large-scale expansion.
