Hello,

To answer question #3 reprossesing PET reduces the intinsic melt viscosity and reduces other properties through heat degredation. A chain extender can be added to the reprocess of flake to bring the IV back up.
The attachement may be useful.

Dear Sir/Madam,

I am currently using the recycing grade of HDPE and PP in producing products such as bucket and container box in Bangkok, Thailand.

Now, I would like to know the feasibility of PET in producing the same products as above and the health-concern over the PET recycle grade.

Please kindly advise,

I have single screw extruder making monofilament.
i am feeding flakes but I get uneven filament due to pressure of feeding of flakes not being constant.
Can you suggest a way to make even melt flow.

Sorry if my questions sound ignorant. I'm a student working on a paper on home-based plastic recycling and remolding. Here are my questions:

1) Is it enough to just wash PET bottles with water and home detergent before cutting them into flakes? Provided the label, glue, and cap are removed?

2) Let's say I have a benchtop injection molder, can I melt recycled PET flakes in it and remold them to let's say small plastic objects like figurines and toys?

3) Does remelting PET flakes destroy its chemical composition in one way or another?
