Polymers have been continuously replacing materials such as metal, glasses and paper due to their varied characteristics and low cost. There are thousands of formula for different plastic industrial.

Except the main application, there are many other plastic compounding for special application.

USEON always have the ability to do the following process:

  • Devolatilization for Polymer
  • Compounding for Rotational Moulding Industrial ( XLPE etc. )
  • Thermosets compounding
  • Wood Plastic Compounding (WPC)
Other Plastic Compounding

Devolatilization for Polymer

Devolatilization is the removal of volatile substances from a solid. It is one of the most important operations in polymer manufacture. We have done several project to take water or solvent liquid 20-40% out of polymer by vacuum system and get the final pellets.

According to the percentage of liquid, we need extruder with long shaft 60-88 L/D, even connect the two extruder in series.
Low screw speed for enough residence time.
Strong vacuum system with heat exchanger and collecting tank for the volatile substances.

Compounding for Rotational Moulding Industrial

Compounding for Rotational Moulding Industrial

Basic Formula:

PE/PP/PC/PA Compounding with color masterbatch and additives.

USEON have supply 8 lines to matrix polymers who is the biggest European distributor for rotational moulding material.

Single Screw Extruder for Coloring Process:

Special mixing zone for minimum waste during changing the color.
Special melting zone for high output and less average energy consumption.
Miller is with cooling jacket which can handle all kind of polymer without sticky.

Twin Screw Extruder for Crosslinkable PE:

Precise temperature control and appropriate screw design to avoid reacting during compounding process.
Typical applications for crosslinkable PE powder include diesel fuel tanks, chemical storage tanks etc.

USEON can supply the completely line from premixing system to miller.

Thermosets Compounding

Most Common Thermoset Types:

Epoxy, Phenolics, Bismaleimide (BMI), Fluoropolymers

Application:

Automobile: Resisters, Drive Motors, Controls, Valve Covers, Oil Pans, Air Suspensions
Electrical: Circuit Breakers, Motor Control, Centers, Generators, Switchgear, Control Cabinets
Marine: Engine Covers, Personal Watercraft, Boat Access Covers, Motor Housing
Powder Coating

Process:

Precise temperature control and appropriate screw design to avoid reacting during compounding process.

Less clearance between screws with better self-cleaning, and very smooth surface of screw and barrel assures that materials do not adhere to surfaces, overheat and degrade.

Split barrel which be opened at up and down direction, for easy cleaning and maintenance.

USEON can supply the completely line from premixing system to crusher.

Wood Plastic Compounding (WPC)

Wood Plastic Compounding (WPC)

Basic Formula:

PP/PE/PVC compounding with wood fiber up to 65%, color masterbatch and additives

Application:

Profile for window and floor and contruction
Sheet for table and door

Process:

  • PP/HDPE melting temperature is more than 170℃, so it is necessary to feed wood fiber from the side feeder.
  • Wood fiber premix additives then feed into side force feeder. USEON supply screw design to avoid over shearing but still good mixing without reducing the length of fiber.
  • For PVC window profile, no need to make compounding material into pellets, just cool down and crush it into powder.

USEON can supply the completely line from premixing to profile/sheet extrusion line.
