I have the laminate flooring installed and wood quarter round around my wallsI think some kind of quarter round or trim will look better up against the curves of my stairsI just dont like the way the flooring looks where it ends with the stairs.
The stairs get a lot of wear trafficI would use a metal trimYou can purchase several different types at most hardware storesThe shapes vary but I think metal would hold up better than woodYou can get aluminum in different colors and should give you a good finished look.
Depends on the type of material and the type of plasticmost plastic is made from PVC which is polyvinylchoride, you can have polyester which is a polymer chain compound of esters Or there is polystyrene which is the polymer chain of styrene, a hydrocarbon of some sort Hope i helped
