NTM plastics come in two tiers, “normal” plastic (“ingotAnyPlastic”), that being polymer (actually teflon, “ingotPolymer”) and bakelite (“ingotBakelite”), then there’s hard plastics (“ingotAnyHardPlastic”), being hard plastic (actually polycarbonate, “ingotPolycarbonate”) and PVC (“ingotPVC”, reinforced with cadmium). Then there’s also rubber which is counted as its own thing (“ingotRubber”). There are a few oddities related to how plastics got grouped together and how teflon is just called “polymer”, but that’s because of how much time had passed between any of these being added, with the entire oil sector growing a lot in the past three years.
