(1) Thermal insulation and cold insulation—its fine independent bubble structure effectively reduces the energy exchange caused by air convection, and is more thermally insulated and cold-proof; (2) Cushioning performance—its semi-rigid foam has no loss of reduction performance after strong impact, high resilience and tension resistance, strong toughness and long life; (3) Water resistance-airtight cell structure, non-absorbent, moisture-proof, better water resistance; (4) Corrosion resistance-resistant to chemical corrosion such as seawater, grease, acid, alkali and more antibacterial, non-toxic, odorless, and pollution-free. Absolutely environmentally friendly!
