How to create PU foam?

Are you struggling to understand foam production? It can seem like a complex chemical process, but the basic principle is surprisingly simple. Creating polyurethane (PU) foam involves a chemical reaction between two main liquid components: a polyol blend and an isocyanate. When mixed, they react, expand, and cure to form a solid foam. The final […]

How to calculate the expansion ratio of Polyurethane foam?

Confused by foam expansion calculations? Getting it wrong wastes materials and results in bad foam. I’ll show you the simple math and what truly matters for your production line. To calculate the expansion ratio, divide the final foam volume by the initial liquid volume. For example, if 100ml of liquid expands to 3,000ml, the ratio […]
