PVC substitute
PVC substitute
(OP)
Hi there,
I am looking for a PVC substitute.
We frequently use rigid PVC for manufacturing small and testing parts.
It is cheap and easy to manufacture.
The problem we are currently facing is we are not allowed to use it due to fire regulations; when burning PVC gives off carbon monoxide which is toxic.
For what I found around, one could use PP or PE (Polypropylene and polyethylene) with fire retardants.
Actually it seems most of plastics are not allowed or recommended: ABS, POM, PVC, PVDC, PVDF and many others one should get them with the fire retardants.
Does anyone have experience about this?
thanks
regards,

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

PE and PP burn like a candle and very cleanly. If you need it to be FR then there are many such formulations on the market. In PE, ATH is most commonly used. In PP, MDH is used as an FR agent.

RE: PVC substitute
Aluminium would be too conductor and not so easy to machine
PVC is completely forbidden since it is not halogen free
How do these fire retardants work? I mean, I guess they should be added in the melting process. Are there standard materials ready to buy?
thanks

Also take a look at Bakelite.
