Biodegradable Twin Screw Plastic Extruder Strand Pelletzing Extrusion Pelletizing Machine

Twin Screw Extruder for Biodegradable Material With Air-Cooling Strand Pelletzing Production Line

Twin Screw Extruder

A twin screw extruder, also known as a co-rotating twin screw compounding extruder, is one of the most advanced and versatile machines used in polymer compounding, plastic modification, masterbatch production, and recycling. With its modular screw design and superior mixing capabilities, the twin screw extruder delivers excellent dispersion, strong shearing performance, precise material blending, and consistent pellet quality.

The extruder utilizes intermeshing co-rotating screws, multi-zone temperature control, and highly efficient feeding systems to process a wide range of materials, including engineering plastics, color masterbatch, filler masterbatch, biodegradable materials, elastomers, and recycled plastics. This makes it an ideal solution for both industrial production and research applications.

Applications of the Twin Screw Extruder

Plastic Compounding: PP, PE, ABS, PA, PC, TPU, TPE, PET, PBT.

Masterbatch Production: color masterbatch, additive masterbatch, filler masterbatch.

Engineering Plastics Modification: flame-retardant, reinforced, impact-modified materials.

Biodegradable Compounds: PLA, PBAT, PHA, starch-based blends.

Nano-Material Dispersion: carbon black, calcium carbonate, talc, nano-fillers.

Recycling & Reprocessing: mixed plastic waste, industrial scraps, post-consumer materials.
