Features

How it's made

The plastic melt is spun out through a nozzle, which consists of a row of several hundred pin holes. Hot air flows out on both sides of the nozzle tip transforming the polymer streams into very fine filaments. These filaments are drawn by high speed hot air onto a filter belt. The result is a melt-blown fleece with particularly good barrier and filtration properties.
