Flow Improver

The bFI flow improver family: a multiplier for your processes

Our flow improvers were developed to make a universal contribution to optimising the processing of your plastics. The main representative bFI A 3745 offers you several advantages. The additive is a flow improver, energy saver and pioneer. It enables you to produce more delicate components, rationalise your purchasing range, reduce your CO2 footprint, significantly reduce cycle times and much more. Most importantly, the mechanical properties of your material are retained. See for yourself and request a sample directly.

Optimizing the melt viscosity with our flow improver bFI

Flow improvement with bFI: Get ahead with us!

A picture is worth a thousand words. As old as this sentence is, it is still true today. The flow spiral on the left in the picture opposite was produced with a conventional polymer mixture. The picture on the right clearly shows the significant influence of the bFI A 3745 used. You too can get more out of your material with the polymer flow improvers from Polytives.

flow improver properties

Increase productivity with increased MVR

The meltflow rate is an essential parameter for the effectiveness of flow improvers such as our bFI A 3745. Its use promises you convincing results in almost all polymer systems. The mechanical properties are retained. The additive is available as a powder or granulate and we are happy to support your sampling with our previous experience. In addition to its high compatibility, the additive is characterised by its positive effects on flow behaviour even at dosages in the single-digit percentage range. Furthermore, recyclability is guaranteed, and bio-based and recycled materials receive a quality boost.

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
