Top 10 Companies in the Global Graphite PolyStyrene (GPS) Market (2026): Market Leaders Powering Global Energy‑Efficient Construction

MARKET INSIGHTS

The Global Graphite PolyStyrene (GPS) market size was valued at USD 1.98 billion in 2025. The sector is projected to grow to USD 2.14 billion in 2026 and reach USD 3.21 billion by 2034, reflecting a CAGR of 7.2% over the forecast period.

Graphite PolyStyrene (GPS) is an advanced insulation material composed of expanded polystyrene infused with graphite particles. This composition significantly enhances thermal performance by reflecting and absorbing infrared radiation, thereby reducing heat transfer more effectively than traditional polystyrene. GPS is primarily manufactured as rigid foam boards or panels and is widely utilized for its superior insulating properties, moisture resistance, and structural integrity.

Fuelled by the rising demand for energy‑efficient building solutions and stringent regulatory standards for thermal insulation, GPS adoption is accelerating. Growing investments in green building certifications and sustainable infrastructure development further reinforce this momentum. Key industry players, including BASF SE, Knauf Insulation, and Kingspan Group, are expanding production capacities and introducing innovative product variants to meet evolving market requirements, particularly in residential and commercial construction sectors.
