Density Separation in Plastic Recycling: How Sink-Float Sorts Plastics by Weight
Density separation sorts mixed plastics by whether they float or sink in a liquid, and it is the cheapest way to split polyolefins from heavier resins. This guide explains how a sink-float tank works, which plastics float and which sink, what density separation can and cannot do, and how it compares with electrostatic and eddy-current sorting.

Plastic Density Chart: Which Plastics Float and Which Sink in Water
A reference density chart for common recycling plastics — PP, PE, PET, PVC, PS, ABS, and more — with each resin's density in g/cm³ and whether it floats or sinks in water. Includes how fillers shift density, why some resins overlap, and how recyclers use the chart to sort plastic by sink-float.
03
Plastic Sorting Methods: How to Choose Between Sink-Float, Air, and Electrostatic Separation
Every plastic sorting method works on one physical property — density, weight, surface charge, conductivity, or polymer fingerprint. This guide compares sink-float, air classification, electrostatic, eddy-current, and NIR sorting, shows what each one separates, and gives a decision framework for matching the method to your contamination.
04
Centrifugal Dryer for Plastic Recycling: How Spin Drying Removes Surface Water from Flake
A centrifugal dryer spins washed plastic flake at high speed to throw off free surface water mechanically, before any heat is applied. This guide explains how a centrifugal drying machine works, where it sits in a wash line, the residual moisture it reaches, how to size one for film versus rigid flake, and when you still need a thermal stage after it.
Frequently Asked Questions
Common Questions About Our Recycling Systems
What types of plastic waste can your machines process?
Our industrial recycling systems process a wide range of materials including PET bottles, PE/PP agricultural films, rigid plastics (HDPE/PP) and 3D printing waste into high-quality reusable pellets.
Do you provide complete turnkey recycling plants?
Yes, we design, manufacture, and install complete turnkey lines covering shredding, washing, drying, and pelletizing, tailored to your specific feedstock and factory layout.
How do you ensure the quality of the recycled pellets?
We ensure high-output purity through multi-stage friction washing, precise density separation, and advanced thermal drying and vacuum degassing during the extrusion phase.
Can your equipment handle highly contaminated plastics?
Absolutely. Our heavy-duty shredders and specialized hot washing modules are engineered specifically to handle post-consumer waste with high levels of dirt, oil, and paper labels.
Do you offer international installation and training?
Yes, our global engineering team provides on-site installation, system commissioning, and comprehensive operator training worldwide to ensure your plant runs smoothly.
