PU-ZDHR040 is a fully-formulated high-resilience (HR) polyol system for moulded automotive seat foam — seat cushions, backrests, headrests and armrests. HR foam gives the firm, buoyant support and long fatigue life that vehicle seating demands, with good air permeability for all-day comfort. A two-component blended-polyol system (polyol + isocyanate) with stable, fast reactivity tuned for cold-cure moulded seat production.

Key Features
High resilience & support Buoyant, supportive seating feel with fast spring-back — the HR standard for vehicle seats.
Long fatigue life Resists sagging and softening over years of repeated loading and vibration.
Good air permeability Open structure breathes for cooler, more comfortable long-drive seating.
Stable, fast reactivity Cream 10–13 s / end-of-rise 53–60 s for consistent moulded parts and short cycles.
Cold-cure mouldable One-shot cast moulding into seat cushions, backs and headrests with fabric inserts.
Customizable firmness Density and firmness tuned per seat zone (bolster, cushion, back). OEM/ODM.
