PP Market Pricing Strengthens Amid Higher Replacement Costs

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.
