Plastics Pricing Intelligence - Executive Summary
Plastics pricing intelligence recorded diverse but generally stable conditions during August 2026, with selective strength across thermoplastics. Polyolefins including HDPE, LLDPE, LDPE, and PP recovered after early weakness as tighter Asian petrochemical availability and higher crude, naphtha, and ethylene costs increased replacement costs. ABS strengthened more clearly on higher styrene costs, while PS saw a moderate late-month recovery. PVC improved temporarily mid-month but remained constrained by comfortable supply and uneven construction demand.
 
PA6 strengthened in the second half as higher benzene and caprolactam ...
... costs supported resin prices, while PA66 recovered part of its early decline and polycarbonate maintained an upward trend. However, automotive, appliance, electrical, and industrial buyers remained cautious with inventories. Polyesters and copolymers were comparatively stable, with EVA supported by maintenance and tighter availability. Overall, August plastics pricing was driven mainly by feedstock costs, production constraints, and logistics rather than broad-based end-user demand growth.
Key Price Developments & Insights

HDPE, LLDPE, and PP recovered after early weakness as tighter Asian supply and higher ethylene and propylene costs supported prices.
ABS strengthened as higher styrene and aromatic feedstock costs raised replacement values, despite uneven appliance, electronics, and automotive demand.
PVC remained subdued, with only a temporary mid-month improvement due to ample supply and weak construction demand.
PA6 and polycarbonate strengthened, while PA66 remained balanced due to differences in feedstock costs, supply, and automotive, electrical, and industrial demand.
EVA remained stable, while PET recovered as constrained MEG availability, logistics issues, and lower operating rates influenced the market.

Plastics Sector Coverage and Key Price Influencers
1. Thermoplastics
The thermoplastics category includes polyolefins, styrenics, vinyls, polyamides, and polycarbonates. These high-volume resins are widely used in films, packaging, pipes, construction materials, appliances, automotive components, household products, and various industrial applications.
Key Pricing Influencers:

Crude oil, naphtha, ethylene, propylene, benzene, and styrene costs
Middle Eastern PP availability and freight reliability
Producer operating rates, inventories, and new Asian capacity
Packaging, construction, automotive, appliance, and consumer-goods demand

2. Polyesters & Copolymers
The polyesters and copolymers category includes ethylene copolymers and polyester resins. EVA is commonly used in solar encapsulation, films, footwear, foams, cables, and adhesives, while PET is primarily used for beverage bottles, food and pharmaceutical packaging, films, and sheets.
Key Pricing Influencers:

Ethylene, vinyl acetate, PTA, and MEG availability
Packaging and beverage requirements
Solar-encapsulation and general-purpose EVA demand
Producer operating rates, Asian capacity, and recycling requirements

Pricing Trends, August 2026

Thermoplastics

Thermoplastics remained broadly stable in August after a weaker start. HDPE, LLDPE, and PP recovered as buyers focused on immediate requirements, while PS strengthened on higher styrene-related costs. PVC saw a brief mid-month rise before easing as supply remained adequate and construction demand stayed weak. PA6 and polycarbonate strengthened on higher input costs, while PA66 recovered after early weakness. Automotive, electronics, electrical, and industrial demand provided support, but buyers remained cautious due to regional and application-level demand differences.

Polyesters & Copolymers

EVA remained relatively stable, supported by maintenance and low producer inventories, while weaker general-purpose demand limited gains. Photovoltaic and general-purpose grades continued to show different demand patterns. PET recovered after early weakness as MEG availability tightened and some producers reduced operating rates. Packaging demand provided baseline support, while buyers maintained disciplined procurement.

Plastics Key Market Drivers

Middle East disruption and feedstock costs: Strait of Hormuz disruptions continued affecting energy and petrochemical flows, keeping crude, naphtha, and olefin costs elevated. Higher feedstock and logistics costs pressured polyolefins, styrenics, and engineering plastics, although cautious downstream demand limited producers’ ability to fully pass on increases.
Tight supply and lower operating rates: Weak cracker economics and feedstock disruptions led some Asian producers to reduce operating rates. Tighter olefin availability, lower EVA output, and reduced polyester production amid MEG constraints supported selected resin prices despite moderate demand.
Weak demand and cautious inventories: Packaging demand remained relatively stable, while automotive, construction, appliances, and durable-goods demand was uneven. Converters maintained lean inventories and smaller purchases, limiting sustained resin-price increases despite higher feedstock costs.
Expanding Asian capacity and oversupply: China’s growing PP and polyethylene capacity continued to offset short-term supply tightness. Expectations of medium-term oversupply encouraged buyers to maintain conservative procurement.
Packaging regulation and trade uncertainty: New EU packaging rules and updated UK EPR guidance increased focus on recyclability, recycled content, reporting, and traceability. U.S.–Canada trade tensions also added uncertainty to North American plastics trade, making regional sourcing and material selection increasingly important.
