{"product_id":"black-coexnylex™-unfilled-nylon","title":"Black CoexNylex™ Unfilled Nylon Filament — COEX 3D","description":"\u003cp\u003eCoexNylex™ Unfilled Nylon is a pure PA12 formulation — no glass or carbon fill. It delivers nylon's characteristic toughness, fatigue resistance, and chemical resistance in an isotropic, unfilled form. Use it for parts where layer-to-layer isotropy matters: living hinges, flex arms, gear teeth, and chemically exposed components.
