Customised plastic recyclate from inexpensive recycling raw material.
When recycling plastics from in-house or post consumer waste there are inevitably quality fl uctuations which often limit the amount of recyclate in the end product. The solution lies in systematic upcycling, i.e. the combination of recycling and compounding.
This enables you to optimise the property profile with precision according to your requirements.
POLYTEC brings together all the benefits of recycling and compounding in one system for the first time. The proven, robust POLYTEC technology is used to turn recycling raw material (e.g. PP nonwoven, PE edge trim, PA fibres etc.) into a filtered melt which then goes directly to a co-rotating twin-screw extruder from Coperion. With its excellent mixing and gas removal properties, this part of the system can handle all compounding tasks.
Besides the dosing of a wide variety of additives, fillers and reinforcing agents can be admixed in doses that are higher than those previously possible with POLYTEC recycling systems. The result is customised plastic recyclate for high-quality applications. for the first time.

How it works
Feeding is automatic according to customer requirements.In the patented preconditioning unit the material is cut,mixed, heated, dried, degassed, densified and buffered.Next, the tangentially connected extruder is fi lled continuously with hot, pre-compacted material.
In the extruder screw 3 the material is plasticised, homogenised and then cleaned in the fully automatic self-cleaning fi lter .The prepared and cleaned melt then goes via the melt pump directly to the co-rotating, self-cleaning twin-screw extruder from Coperion. With its excellent mixing and gas removal properties, this fl exible part of the system can handle all compounding tasks.
Besides the dosing of a wide variety of additives, high amounts of fi llers and reinforcing agents can be admixed. In the degassing zone the compounded melt is degassed and moves to the respective tool (e.g. POLYTEC hot die face pelletising system).
preconditioning unit: cutting, mixing, preheating,
drying, degassing, compacting, buffering recycling extruder: plasticising, homogenising
melt filter: fully automatic and self-cleaning
twin-screw compounding extruder:
• Admixing of additives, fillers and reinforcing agents e.g. up
to 80 % CaCO3 , 50 % glass fibre, colour
pelletising systems:
• For consistent pellet quality
