Additive Masterbatch

Any plastic product needs at least two types of additives to modify its physical or chemical properties, such as flame resistance, thermal stability or weather resistance. USEON provides pelletizing lines for all kinds of additive masterbatch, designed around your formulas and circumstances.

  • Engineering plastics
  • PET
  • Rigid PVC
  • Pipe coating

Processing of additive masterbatch

Two facts shape an additive masterbatch line.

Output depends on feeding, not torque

The bulk density of additives is relatively low, so the output depends mostly on the feeding capacity, not on the torque of the main motor.

One extruder, many formulas

One extruder should be able to make many types of additive masterbatch, so it needs a fast-cleaning strand die plate for formula changes.

Feeding AVolumetric

Premix process with volumetric feeder

  1. Weigh each material
  2. High-speed mixer 5–10 min
  3. Spiral loader
  4. Volumetric feeder hopper
  • Each raw material is weighed separately according to the formula.

Feeding BAutomatic · higher accuracy

Split feeding by loss-in-weight feeders

  1. Tanks on the ground
  2. Vacuum loader / liquid pump
  3. Storing silo
  4. LIW feeders → extruder
  • Each component is fed separately according to the formula set on the HMI.
  • Shear-sensitive additives enter the fifth barrel by side force feeder; its water-cooling jacket protects powders with a low melting temperature.

Technical specifications of the extruder

Because output follows feeding capacity, our SAT twin screw extruder suits this process.

Tell us the additives you compound, their form (liquid, pellet or powder), the carrier resin and how often your formula changes. We size the feeding first, because that is what sets the output.
