PVC generally offers excellent weather resistance and chemical stability but may release toxic additives if not properly stabilized. Polypropylene provides superior impact resistance and chemical resistance, with a lower environmental footprint if sourced as recycled material. Consider end-of-life disposal—PVC can be more challenging to recycle and may emit toxins if incinerated, whereas PP is more recyclable in many regions. Balance durability needs with environmental considerations, and select suppliers committed to sustainable practices to align with your corporate responsibility goals.
