Flow Improver

The flow improver bFI – a multiplier for your products & processing operations

Our flow improver was developed to help optimize conventional thermoplastics and their processing. The bFI offers three benefits at once: The additive is a flow improver, energy saver and pathfinder. Architecturally targeted polymer design makes this possible. The flow improver bFI will ensure a technological leap forward for you by making plastics more filigree and processable with less energy input. The mechanical properties remain unchanged.

flow improver properties

Reduce melt viscosity – increase productivity

The flow improver bFI was developed to reduce the melt viscosity of PMMA. However, it can also be used in other polymers or casting resin mixtures and achieves excellent results. bFI is available as powder or granules – contact us for application questions about the flow improver. In addition to the high compatibility and miscibility, the positive effects on the flow behavior are already evident at dosages of 5 – 10%. You do not have to integrate this part of the additive additionally. You replace part of your base polymer and, for example in PMMA, retain the transparency and recyclability of the polymethyl methacrylate, while the MFI is significantly improved. Learn more or test it directly yourself.

Flow improvement through bFI – visibly moving more

A picture is worth a thousand words. As old as this sentence is, its truth content is still great today. The flow spiral on the left in the adjacent picture was produced with a conventional polymer blend. On the right, the significant influence of the bFI flow improver is clearly visible.

Break through technical limits with the innovative flow improver bFI and enter the next generation of plastics

With the flow improver bFI from Polytives, you not only optimize your processing and generate benefits for your plastic products. You also get the opportunity to use an additive that does not compromise on sustainability.

Recyclability is not affected; this saves you energy and thus CO2. The label-free use of our Flow Improver and the resulting process optimizations also speak a clear language in figures. Depending on the application, you benefit:



Reduce processing tem­pe­ra­tu­res and produce as usual. Energy savings of up to 33% are possible.


Energy saving



Work up to 1.5 times more efficiently than previously possible: in­crea­se your output by 50% with the same pro­duc­tion time.


Throughput increasing



Shorten your lead times – due to the increased throughput, your pro­duction time is reduced up to 48%.


Time saving
