SLS Glass-Filled Nylon PA12

Nylons
Wear resistantFunctionalHeat resistant

SLS glass-filled nylon PA12 is standard PA12 filled with glass beads, typically about 40% by weight. The glass makes it roughly 1.5 to 2 times stiffer than unfilled PA12 and raises heat deflection under load by roughly 30 °C (to ~96 °C), while tensile strength stays similar. Elongation roughly halves in the layer plane (about 9% vs. 18%), and stiffness is lower across the layers than within them. Thin walls and fine features are therefore more fragile. SLS glass-filled nylon PA12 is a strong choice for rigid housings, thermally stressed parts, and tooling.

Available finishes

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

Polished

Polished

4 colors

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

Shot Peened

Shot Peened

4 colors

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

Standard

Standard

17 colors

The standard finish on SLS glass-filled nylon PA12 has a matte, grainy surface in off-white to light gray that is rougher than unfilled nylon, with no support marks.

Vapor Smoothed

Vapor Smoothed

0 colors

Vapor smoothed SLS glass-filled nylon PA12 has a smooth, uniform, semi-gloss, sealed surface with the grainy SLS texture largely removed. Sharp edges and fine details are slightly softened.
