Tightening limits keep moving constructions up
Evaporative emission rules across North America, Europe and Asia have ratcheted permeation limits downward on published timetables toward around 15 grams per square metre per day, and each step obsoletes a construction that was compliant the year before. Surface treated rubber gave way to fluoroelastomer liners, which gave way to coextruded fluoropolymer barriers. Every step raises material cost per metre without adding a metre, which is why category value compounds while volume does not. Suppliers who invested in coextrusion capability early are now supplying constructions that competitors cannot yet manufacture at all.
