Product Details

Sponge Foam Release Paper is a PE-coated kraft paper specifically designed for polyurethane (PU) foam production lines. It acts as a disposable liner between the foam mixture and the production equipment. Once the foam is cured, the paper peels off cleanly — leaving both the foam surface and the equipment spotless. No scraping. No solvent. No downtime.
Key Advantages

Fast Peel, Zero Residue — PE layer separates cleanly from cured foam; no foam left on equipment
Cuts Cleaning Downtime — Switchover between batches in minutes instead of hours
No Chemicals Required — Eliminates the need for solvents or aggressive cleaning agents
Extends Equipment Life — Protects conveyor belts and molds from foam buildup and mechanical damage
Good Tensile Strength — Won't tear during laying or peeling, even at wider widths
Consistent Release Performance — Same peel behavior across the entire roll, every batch
Custom Weight & Width — Matched to your specific production line specifications
Applications

PU foam block / slab production lines (continuous pouring)
PU foam molding (shaped foam parts)
Memory foam, high-resilience foam, and flexible foam manufacturing
Sponge mattress and cushion production
Any foam curing process requiring a clean release surface
