As global attention increasingly focuses on "carbon neutrality" and the circular economy, environmental protection has emerged as a core driving force within the foaming industry:
**The Rise of Non-Isocyanate Polyurethanes (NIPU):** While traditional polyurethane (PU) foams rely on toxic isocyanates, NIPU technology is rapidly maturing. By eliminating toxicity risks at the source, NIPU is regarded as a key developmental direction for the next generation of polyurethane foams-particularly in sectors with stringent health and environmental standards, such as construction and automotive interiors.
**Breakthroughs in Bio-based and Biodegradable Materials:** Beyond common materials like PLA, fully cellulose-based bio-foams have now been successfully developed. Utilizing natural cellulose sources-such as wood-as raw materials, this new class of materials is not only biodegradable but also demonstrates superior heat resistance and mechanical strength (with a compressive modulus reaching up to 11.8 MPa) compared to traditional petrochemical-based foams, offering entirely new options for packaging and building insulation applications.
**Surging Demand for 100% Recyclable Expanded Polypropylene (EPP):** Driven by its inherent 100% recyclability, EPP is experiencing a surge in demand across sectors such as protective packaging for new energy vehicle battery packs, cold chain logistics, and high-end packaging. The industry is currently accelerating the establishment of closed-loop recycling systems, with the incorporation ratio of recycled content already reaching between 15% and 30%.
