Durable Ergonomic PU Integral Skin Foam Armrest Assembly
Engineered for passenger, commercial, and engineering vehicles, this polyurethane integral skin foam armrest features an ergonomic T-shaped design that provides natural support for the elbow and forearm. Manufactured via a single-mold reaction injection molding process, it integrates a dense, wear-resistant outer skin with a soft, shock-absorbing microcellular foam core around a pre-embedded metal skeleton. It offers exceptional structural durability, joint relief, and long-term resilience without sagging or cracking over extended use.

Outer Integral Skin Foam Layer
Density 450 to 600 kg/m3, Shore A 65 to 80; Wear-resistant, scratch-proof, pressure-resistant, and non-peeling.
Internal Foam Core Layer
Density 180 to 240 kg/m3, Shore A 35 to 45; Soft, supportive, and ergonomic arm cushioning.
Overall Assembly Average Density
200 to 280 kg/m3; Semi-rigid feel balancing structural strength with tactile comfort.
Abrasion Resistance
Withstands 5000 cycles of steel wool reciprocating friction without base exposure or cracking.
Compression Permanent Set
5% or lower (Tested at 50 degrees C under constant pressure for 22 hours); Resists permanent sagging.
Tear Strength
3.5 N/mm or higher; Prevents edge tearing during flexing, installation, or torque locking.
Resilience Rate
48% or higher; Rapid spring-back recovery after arm release with zero indentations.
Flammability Rating
GB 8410-2017 and FMVSS 302 automotive interior flammability compliant.
Odor & VOC Level
Grade 3 or lower low-VOC odor rating, meeting passenger vehicle eco-standards.
Operating Temperature
-40 to 90 degrees C; Non-sticky under summer sun exposure and non-brittle in extreme winter cold.
Humid-Heat Resistance
Passes 500 hours cycle testing at 70 degrees C and 95% RH without cracking, discoloration, or mold growth.
Stain Resistance & Cleaning
Dense, non-porous skin surface prevents liquid penetration and wipes clean easily with wet towels.

Structural Layering
- Dual-Density Ergonomic Comfort: High-density outer skin (450-600 kg/m³) resists scratches, while the soft inner core (180-240 kg/m³) provides gentle, non-stiff arm cushioning.
- Heavy-Duty Embedded Skeleton: Pre-embedded metal steel plate inserts guarantee rigid mounting, high structural torque, and seamless fitment onto locking mechanisms.
- All-Weather Resilience: Operates reliably from -40°C to 90°C, preventing softening in summer heat or brittleness in winter cold.
- Manufacturer Advantage: Advanced in-house mold tooling, customizable mounting insert structures, and high-capacity OEM/ODM production for global auto tier-1 suppliers.
