Is there a difference between "Melt Index Brushes" and the "Barrel Brushes"?

The melt index brushes listed are the diameter sizes most requested by labs performing the melt index or rheometer tests. The barrel brushes are used to clean a variety of lab tubes and machine parts. However, brushes are interchangable with the end users preference.

Which brush is recommended for my machine?

The diameter of the barrel that you are cleaning would dictate the size brush you require. We recommend the .406" diameter brush (#11012) for your melt indexer, however any of the brushes listed in the Melt Index Brush section are regularly ordered.

UPS is our primary shipper however, arrangements can be made for FEDEX, DHL or other carriers your company prefers. Please give us a call or complete the contact page in order for arrangements to be discussed.

Can a brush be used more than once?

Although we do not recommend more than one time usage, many customers use the same brush for several cleanings. It mainly depends on what polymer you are testing.

Why use a brush and a patch to clean the machine?

The brush helps to remove stubborn deposits while the patch helps to absorb and wipe away residue.

What is an orifice brush?

The orifice brush was designed by our company to remove any polymer that remains in the die after the testing is completed. By using a brush instead of a drill-bit, you maintain the integrity of future tests.

What difference is there for the stainless steel and bronze orifice brushes?

We recommend using brushes with a brass or bronze fill because it is softer wire than steel. Some customers feel that a stainless steel orifice brush cleans better because of the density of the polymer being tested. This brush is still better than using a drill-bit that could change the diameter of the die.

Are there any negative affects to the MI barrell using the stainless steel rods?

No, the rod was designed to be used in the melt index and will not scratch or damage the barrel.
