Where Polyurethane RIM Is Used in North American Manufacturing

RIM polyurethane fascias were the pre-1990s answer and survive on a few low-volume and specialty programs; slower cycle and higher scrap than TPO injection

RIM urethane spoilers on older and low-volume programs; slow cycle, heavy, and needs priming

Encapsulated glass edges are RIM polyurethane molded directly onto the glass with the seal lip as part of the encapsulation; the glass supplier or roof module Tier 1 does this, and it takes the extruded seal out of the bill of material on fixed panels

RIM-processed integral-skin systems on larger console lids and rear fold-down armrests where the part is big enough to justify a closed mold and high-pressure mix head

pDCPD RIM (Telene, Metton) wins on tractor and construction hoods where volumes fall below SMC break-even and impact toughness matters more than Class A gloss

pDCPD and PU RIM bumpers on aero Class 8 and on construction cabs: molds cheaply at low volume, absorbs impact, and can be sectioned for repair

pDCPD RIM fairings on some Class 8 programs where impact toughness and repairability beat SMC

PU RIM dashboards mold the full wrap-around driver panel in one shot with a self-skinning surface, at tooling costs that suit sub-20k volumes

pDCPD RIM cab panels on large construction machines where a single tool covers the annual volume

pDCPD RIM fenders on large ag and construction machines where the part is too big for injection and the volume is too low for SMC

Integral-skin polyurethane gives an ATV or golf car seat its wear surface and its cushion in one pour, with no vinyl cover to tear; used on utility and fleet seats where looks matter less than durability; see TAXONOMY GAP polyurethane-semi-rigid

Integral-skin seats on utility and rental snowmobiles where a torn vinyl cover would otherwise let snow melt into the foam; see TAXONOMY GAP polyurethane-semi-rigid

A closed-cell integral skin over the cushion foam, or a self-skinning pour, is what keeps water out of the core on the premium seats; the skin is the specification, not the foam under it; see TAXONOMY GAP polyurethane-semi-rigid

RIM-molded large hoods and cowls on utility vehicles and low-volume models where tooling cost rules out injection

Self-skinning integral-skin polyurethane forms its own wear surface against the mold and needs no cover or cap, which is why it survives on lounge and healthcare arms that get cleaned with a disinfectant that would destroy a fabric

Self-skinning polyurethane edges are molded directly onto the worksurface substrate, so the edge is bonded rather than applied and cannot be peeled off at a corner; the durable answer on training tables and healthcare surfaces that take cart impacts
