Flow & surface improvers

Faster, fuller mould fill and a cleaner release — so you can run cooler and cycle sooner.

Flow & surface improvers

Polymer flow improver by process

One Fischer-Tropsch additive working in three places: inside the compound, between polymer and filler, and where the melt meets the machine.

Injection moulding

The melt flows into the mould faster and fills it further, with better release from the tool. That lets you lower operating temperatures and shorten cooling time — even on hard-to-mould, low-MI HDPE parts such as bins, lids, handles and wheels.

Film, fibre and tape

Better melt flow and a better surface on the finished film, fibre or tape — with metal release at the die.

Rubber extrusion and engineering polymers

The same flow and release benefits in rubber extrusion and in engineering polymers, where processing temperatures leave little headroom.

Straight answer

The straight answer on flow improvers

Where it earns its place, and where we will point you to something else.

Where it wins

  • Faster, fuller mould fill — run at lower temperatures with shorter cooling.
  • Metal release and lower melt viscosity from one additive.
  • Fits your existing process without equipment changes.

FAQ

Flow improver questions, answered

Not here? Send it to us — a line or two is enough.
What does a flow improver do in injection moulding?

It lowers melt viscosity and improves release from the tool, so the mould fills faster and further. That lets you run cooler and shorten cooling time.

Which polymers does it work in?

Polyolefins, styrenics and engineering polymers, plus rubber, compounds and masterbatch.

Will it help with low-MI HDPE parts?

That is exactly where it earns its place — large, hard-to-mould parts such as bins, lids, handles and wheels.

Do I need new equipment to use it?

No. It is a coarse powder that goes into your existing dosing.

How do I trial it?

Send us the polymer, the part and the problem. We will suggest a starting addition level for a trial on your line.
