Understanding PS resin prices
Raw materials and production
Polystyrene is a thermoplastic produced from styrene. General-purpose and impact-modified grades have different properties, while expanded forms require additional processing. A resin quotation is not the same as a finished foam-product price.
Applications and consumption
Packaging, disposable articles, appliance components and insulation-related products use polystyrene in different forms. Manufacturers select grades for stiffness, impact behaviour and processing. Changes in product design or packaging choices can alter demand for particular grades.
What affects PS resin prices?
Styrene costs, plant output, manufacturing orders and stocks influence polystyrene prices. Energy and transport contribute to delivered costs. Grade and product form should be matched when comparing general-purpose resin, impact-modified material and expanded products.
How to read PS resin price today
This page follows PS resin in China. The price type is Spot assessment, with values expressed in CNY/t. Compare quotations only after matching the product specification, unit, market and publication period. Changes in the chart describe the recorded series; they do not measure every transaction in the wider market. A local purchase may include freight, processing, taxes or dealer margins. Differences in quality or delivery conditions can therefore produce a different final cost even when the reference price is unchanged.
The latest dated observation is the reference available on this page. Trading holidays or publication delays can leave the displayed date earlier than today; this is not a live tick feed.
