Applications of Arkema Rilsamid® AMN BLACK P20 TLD PA12 in Industrial Manufacturing

Arkema Rilsamid® AMN BLACK P20 TLD PA12 is a specialty polyamide 12 grade engineered specifically for demanding technical segments. As a direct manufacturer, we supply this material for multiple industrial chains requiring high mechanical stability, chemical resistance, surface quality, and regulatory compliance. Below we detail established downstream integrations in real manufacturing sectors.

1. Automotive Fuel Line Systems

Automotive OEMs and tier suppliers widely use PA12 black grades in multi-layer fuel line tubing assemblies, brake lines, and vapor return hoses. This material enables thin-wall, lightweight, and corrosion-resistant conduits demanded in high-pressure environments. Black pigmentation ensures UV protection for under-the-hood and exposed segments. Automated extrusion, co-extrusion, and automated cutting lines leverage this PA12 for precise geometric stability and resistance against biofuels and hydrocarbons.
