Polyurethane Foam Defect Troubleshooting
Every polyurethane foam manufacturer hits production defects eventually — blindness, shrinkage, splits, scorch, voids, density variation, color drift, and more. Most of them have well-understood root causes, but tracing the specific cause on a specific line, with specific raw materials, is rarely simple.
PolymersIQ maintains a practical defect library covering flexible slabstock, moulded foam, rigid foam, and integral skin systems. Each entry describes how to recognize the defect, what causes it most commonly, and what to check first before reformulating or changing process.
Most production foam defects come down to four or five recurring root causes — catalyst balance, raw material drift, reaction profile, process conditions, and mixing efficiency. The trick is identifying which combination is yours, quickly, with the data you already have.
If you don't see your defect listed, send us photos and a short description through the contact page. We'll tell you what we'd look at first, and whether it's something we can help solve.
