If you want cheap plastic that lasts, PETG is the best choice.

Finish

You want your vacuum formed parts to look nice. PETG gives a clear and shiny finish. It works well for packaging or things that need to look polished. Styrene is easy to paint, so you can make colorful models or props. PET is also clear, but it scratches easier than PETG.

Forming Ease

Vacuum forming should be easy to do. PETG heats up quickly and shapes easily. It bends without cracking, so you get good results. Styrene is also easy to shape, but it can bend too much if you heat it too long. PET is stiff, so you need to watch the time when forming.

Tip: PETG helps you save time and money when forming big sheets.

Recyclability

Recycling is good for the planet and your wallet. PET is the best for recycling. It uses recycling code #1 and gets recycled a lot. PETG can be recycled, but not everywhere accepts it. Styrene is harder to recycle and costs more to throw away.

• PET: Recycling code #1, gets recycled a lot, cheap to get rid of.

• PETG: Can be recycled, but not always accepted.

• Styrene: Hard to recycle, costs more to dispose.

Picking PET helps you save money and protect the environment.
