Barrel Blitz Universal: the world’s best universal carbon removal product
Barrel Blitz Universal (BBU) delivers fast colour changes and material changes, and shifts hard-to-remove carbon deposits.
It’s made from a stable, easy-clearing polymer and Aquapurge’s proprietary Scrubber Concentrate. Regular use of BBU reduces the need for screw and barrel cleaning. This frees up key staff, reduces machine downtime and boosts part quality.
Some key attributes of BBU include:
- effective from 160°C (320°F) to 370°C (698°F)
- easily cleaned out by any material, including clear ones (no milky mouldings!)
- ideal as a strip-down material
- effective for higher temperature materials
- ease of use: it’s now available as a free-flowing powder.
Colour changes: BBU allows fast, smooth colour changes by removing all trace of the previous job from the barrel. One trade moulder switched from a black part to a white part within six mouldings, by feeding just 6kg of BBU through the hopper.
Material changes: Some materials do not mix. A classic example is running polyethylene (PE) before polycarbonate, which can lead to milky mouldings. Using BBU ensures that all traces of the PE run are completely removed from the screw and barrel. Recent formulation changes have simplified the process for removing a high temperature material (like nylon) before moulding a lower temperature material (such as a TPE).
Carbon removal: Carbon deposits can easily be removed with BBU to transform a moulding operation. BBU is a mechanical purging compound, and is self-clearing, meaning that all traces of carbonised material will be completely removed without the need to pull the screw.
