Qichen is a manufacturer of industry-standard formulations of spray polyurethane foam systems for residential and commercial construction and retrofit projects.                                                      Spray Polyurethane Foam (SPF) is made by combining two liquid components coming from different containers, during a chemical reaction to form a foam. These two components are generally referred to as the "A" side and the "B" side.                                                                                The "A" side of the system is polymeric methylene diphenyl diisocyanate (PMDI). The "B" side is typically a blend of polyols, catalysts, blowing agent, flame retardant, silicone surfactant, and catalyst.

Part A (ISO) : 250KG/DRUM

Part B (POLYOL) : 220KG/DRUM

Blended polyols are part of the chemical reaction to make the foam. And MDI side serve control the creation of the foam bubbles (“cells”) in the best way, and to provide the various characteristics of the finished product.

Benefits of Spary Polyurethane Foam：

Closed-cell Spray Polyurethane Foam

1. Thermal Performance R-Value* at 5.5-6.0 per inch

2. High moisture barrier

3. High strength and rigidity

4. Resists water

Open-cell Spray Polyurethane Foam

1. Thermal Performance R-Value* at 3.6 per inch

2. Air barrier at full wall thickness

3. Proper strength and Flexibility

4. Absorbs sound very well
