Curved Industrial Polyurethane Integral Skin Foam Armrest
Crafted through an advanced reaction injection molding process, this curved tubular handle-style armrest combines a flexible foam surface with robust internal frame inserts. Designed to attach securely to flip-up, folding, or locking seat mechanisms, it withstands repeated rotational force and heavy leverage. The durable outer skin remains stable under extreme heat and humidity, ensuring year-round reliability in tough industrial environments.

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.
