Fire-retardant sponge, also known as fire-retardant sponge, fire-retardant cotton, and fire-retardant cotton, are generally fire-retardant materials synthesized by adding flame retardants to various polyurethanes. They are mainly used in furniture manufacturing, massage equipment manufacturing, baby carriage manufacturing, decoration, car accessories, Sound absorption of walls, heat preservation pipes, fire doors and fire shutters, etc.
Fire resistance: When the sponge is burning, it will not produce an open flame.
Water resistance: airtight cell structure, good water absorption performance.
Corrosion resistance: resistant to chemical corrosion such as sea water, grease, acid, alkali, antibacterial, non-toxic, odorless, and pollution-free.
Processability: No joints, and easy to process such as hot pressing, cutting, gluing, and bonding.
Anti-vibration: high resilience and tension resistance, strong toughness, and good shock/cushioning performance.
Thermal insulation: excellent thermal insulation, cold-preservation and low-temperature performance, and can withstand severe cold and exposure.
Sound insulation: airtight cell, good sound insulation effect.
The flame retardant is used in the sponge to directly improve the flame retardant and fireproof performance of the product. It can absorb heat and decompose into non-combustible substances at or close to the ignition temperature; it can react with foam combustion products to produce non-combustible substances; it can delay combustion and prevent smoke, causing the ignition part to self-extinguish.
