Usage of rigid PVS vs HIPS
Usage of rigid PVS vs HIPS
(OP)
I recently had a supplier go under and they were supplying an extruded rigid PVC part. Tooling was transferred to a new supplier and they are unable to produce the part in PVC, but would like to offer it in HIPS. I know that the 2 materials are fairly inter-changeable for some applications, but I was hoping someone could help to educate me on any negative affects from the switch to HIPS.
Thanks,
Thanks,

Indoor usage only, with little load bearing conditions, and no deformative stresses applied aside from housing electrical cables.
So most conditions would be ambient and without exposure to any harsh chemicals.

Without looking up properties charts, I think the flexural modulus vs impact strength trade off might be different for both materials. I think PVC will have better impact without sacrificing as much flex mod. I am sure you can look up data sheets yourself.

RE: Usage of rigid PVS vs HIPS
As Pat mentioned though PVC is intrinsically self extinguishing and that might be important for housing electrical cables. HIPs burns readily with lots of black smoke. ABS would work too and has added chemical resistance compared to HIPs and some added cost, but again it won't be fire resistant.

Flame retardant ABS might be a suitable replacement - it is used quite a lot for electrical stuff.
If it's for electrical trunking, then I would find someone who is willing to extrude PVC.
