1 Understanding Mattress Foaming Technology
1.1 The Science of Polyurethane Foam Production
Polyurethane foam formation is an exothermic polymerization reaction between polyols and isocyanates in the presence of catalysts, surfactants, and blowing agents. The foaming machine precisely controls this reaction to produce foam with specific density, hardness, and cell structure properties.
/* Core Chemical Reaction */
Polyol (R-OH) + Isocyanate (R-NCO) → Urethane Linkage Main Components: ├── Polyol (Polyether/Polyester) 50-70% by weight ├── TDI (Toluene Diisocyanate) 25-40% by weight ├── Water (Blowing Agent) 2-5% by weight ├── Silicone Surfactant 0.5-2% by weight ├── Amine Catalyst 0.1-0.5% by weight └── Tin Catalyst (Stannous Octoate) 0.01-0.1% by weight
