In comparison to other synthetic materials, polypropylen (PP) - the material this pot saucer is made of - has got many advantages.
PP is more flexible than e.g. polyamide, but it is stiffer and more solid than for example polyethylene.
This pot saucer will have much contact to irrigating water with supplements, for it will be used in plant cultivation. The material PP is completely non-sensitive against acids and bases in irrigation water. Neither fats and solvers can harm the pot saucer out of polypropylene.
As a matter of fact, this pot saucer for 18x18x23cm pots will protect the subsurface, you put the plant pots on, and to collect surplus water of the irrigation.
The right plant pot for this saucer is the squared flower pot from our shop.
