die buildup

Resins with narrow MWD are often hard to process, which can generate low-MW components, which in turn can cause die buildup.

You may want to test the die buildup chemically to see what's in it.

Resins from some suppliers will generate more die buildup than others, even when the resins have exactly the same specifications.

But processors often have to schedule costly downtime to remove die buildup.

Die buildup, also called die drool, die bleed, or plate-out, can plague any extrusion process.

If die buildup occurs, try a similar grade from another supplier.

Resins with high die swell sometimes have high rates of die buildup.

Processors typically expend time and labor to remove die buildup because they don't know how to eliminate it any other way.

Die buildup is related to stress at the die exit.

Air sweeps also have the benefit that they can cool die buildup so it doesn't oxidize and turn dark.

For example, extreme die buildup often occurs when highly incompatible polymers are melt blended.
