High-density foamed polypropylene custom-shaped for packaging products

When subjected to repeated squeezing and vibration for a long time (such as in automotive shock absorption components and frequent stacking of logistics turnover boxes), the structural stability and resilience of EPP hardly decline, and it is less likely to experience "fatigue deformation". Its service life is much longer than that of similar foam materials like EPS (expanded polystyrene) and EPE (pearl cotton).

This material’s closed-cell structure is the core of its excellent insulation, providing dual protection. It physically blocks heat transfer (isolating external heat and internal cold) and eliminates air-flow gaps (preventing convection-related insulation failure, a problem with open-cell materials), ensuring stable, reliable insulation against environmental changes

This material retains insulation capabilities even in extreme temperatures. In long-term low temperatures (e.g., -40℃ perishable cold chain transport) or high temperatures (e.g., 80℃ industrial equipment insulation), its insulation performance degrades by less than 5%. This minimal loss makes it ideal for strict insulation scenarios—such as vaccine transport boxes (maintaining temperature to protect vaccine efficacy) and industrial pipeline insulation covers (reducing heat loss to improve energy efficiency)




The closed-cell structure can effectively block heat transfer and sound wave propagation, with a low thermal conductivity (about 0.035-0.045W/(m · K)). It is not only an excellent insulation material (such as RV insulation layers, outdoor insulation boxes), but also an ideal sound insulation material (such as building sound insulation boards, automotive sound insulation cotton).

EPP’s closed-cell structure is non-water-absorbent (water absorption <1%, no performance drop in humidity) and resistant to aging/embrittlement from long-term air or UV exposure, with a 5–10 year service life (e.g., outdoor camping gear, logistics turnover boxes). The editor also raises three questions: EPP raw material application fields, its cost, and ways to improve its production efficiency
