The PET (Polyethylene Terephthalate) foam market is gaining significant traction due to its lightweight, recyclable, and high-performance characteristics. Produced mainly from recycled PET bottles, this thermoplastic foam offers a sustainable solution for various structural and insulation applications across industries.

According to Stratview research, “The PET foam market value was US$ 563 Billion in 2024 and is likely to grow at CAGR of 7.3% in the long run to reach US$ 859.2 Billion in 2030”.

Applications of PET foam are diverse and rapidly expanding. In the wind energy sector, it is widely used as a core material in turbine blades due to its strength-to-weight ratio and excellent fatigue resistance. The transportation and automotive industries utilize PET foam in panels, floors, and interior components to reduce vehicle weight and enhance fuel efficiency. In construction, it serves as thermal insulation and structural support in building facades and sandwich panels. Marine and aerospace sectors also leverage its dimensional stability and moisture resistance in composite structures.

Key drivers of the PET foam market include the global push toward sustainability, increasing demand for lightweight and durable materials, and rising recycling initiatives. Its compatibility with various resins, such as epoxy and polyester, makes it highly suitable for composite manufacturing. Additionally, the growth in renewable energy infrastructure, especially wind power, is a major contributor to market expansion. The shift toward electric and lightweight vehicles further amplifies demand.
