StrongHeat resistantChemical resistantFunctional

MJF glass-filled nylon PA12 is standard PA12 with 40% glass beads. The glass makes it about 1.6 times stiffer than unfilled PA12 and raises heat deflection under load to about 121 °C (from roughly 95–106 °C), with properties nearly identical in every direction. The stiffness comes at a cost of reduced strength, elongation, and impact strength, so thin walls and fine features are more fragile. MJF glass-filled nylon PA12 is a good option for rigid enclosures, housings, fixtures, and tooling.

Available finishes

Each finish can be combined with the available colors at checkout.

Standard

Standard

17 colors

The standard finish on MJF glass-filled nylon PA12 has a matte, slightly grainy gray surface, with no support marks.

Shot Peened

Shot Peened

17 colors

Shot peened MJF glass-filled nylon PA12 has a smoother, more even gray surface than raw MJF glass-filled nylon, with loose powder removed and a subtle satin sheen. The grain is softened rather than removed.

Polished

Polished

17 colors

Polished MJF glass-filled nylon PA12 has a smoother, satin-like gray surface with the grainy MJF texture greatly reduced. Tumbling also rounds sharp edges, removes a small amount of material, and can darken edges and fine details.

Vapor Smoothed

Vapor Smoothed

17 colors

Vapor smoothed MJF glass-filled nylon PA12 has a smooth, uniform, slightly shiny, sealed surface with the grainy MJF texture largely removed. Gray parts turn slightly darker, and sharp edges and fine details are slightly softened.
