Heavy Duty Wear Resistant Integral Skin Foam Armrest Assembly

Built for heavy-duty commercial machinery and specialized automotive seating, this rectangular self-skinning foam armrest pad is engineered to withstand harsh operating environments. Featuring an ultra-durable outer skin that withstands severe abrasion without cracking or peeling, the pad returns quickly to shape after heavy compression. Reinforced with an internal steel frame, it provides high tear strength along all edges, ensuring long service life for commercial operators.
Extreme Abrasion Resistance: Passes 5,000-cycle surface friction testing without cracking, exposing base materials, or wearing down.

Parameter
Features
