This sustainability angle is boosting procurement in eco-conscious markets, particularly for lightweight packaging solutions that reduce shipping emissions.

2. High-Density Foam

High-density PET foam, with densities above 100 kg/m³, offers superior compressive strength, impact resistance, and dimensional stability. This makes it ideal for demanding structural applications, such as blade cores in wind turbines or body panels in electric vehicles, where durability under mechanical stress is essential. Its closed-cell structure also provides better thermal and moisture barriers compared to lower-density counterparts.

• Market Insight: High-density PET foam is experiencing robust growth, particularly in the wind energy sector, where it supports larger turbine blades to capture more power efficiently. The segment benefits from advancements in foaming technology that improve uniformity and reduce defects during high-volume production.

• Trend: Asia-Pacific manufacturers are scaling up high-density production to meet surging demand from automotive and renewable energy projects. Innovations like flame-retardant additives are expanding its use in transportation interiors, driven by stricter safety regulations.
