A high-pressure polyurethane mixing head is a small component with an outsized effect on part quality. If the two reactive streams do not meet...

Most polyurethane processing problems that look like a formulation issue turn out to be a mixing issue. In high-pressure systems, mixing is not done...

Most box-foam failures are not visible at the pour station. A block can leave the mold with a cool surface and still hold a...

What You Are Actually Calculating in Box Foaming Ask a production manager how much a box-foaming line can make and the first answer is...

Production teams that thermoform semi-rigid polyurethane blanks rarely fail because the chemistry is wrong. They fail because the box-foaming cell was specified like a...

One of the most expensive decisions in flexible polyurethane foam is made before formula, before plant layout and often before a real annual volume...

A manual cast polyurethane operation can look well controlled for years — until it isn’t. The typical turning point is not a fixed annual...

The batch casting decision looks simple from the outside: heat the prepolymer, meter the curative, mix, pour into a mold, cure, and demold. In...

A polyurethane screening panel that wears out in six weeks instead of six months is rarely a raw-material problem alone. Most of the time...

Most polyurethane roller failures do not start with the roller. They start with a rush to pour. A caster that skips degassing or ignores...
