About the material

Polypropylene (PP) resists most solvents and chemicals, which makes it a wonderful material to manufacture laboratory equipment and containers for a variety of applications. PP also offers good fatigue strength.

Material Finish

Polypropylene is a semi-clear white color by default, but can also come in opaque white on request.

Design Recommendations

Min Wall Thickness

0.5 mm

Min End Mill Size

0.8 mm (0.03 in)

Min Drill Size

0.5 mm (0.02 in)

Max Part Size

1200 x 500 x 152 mm [x,y,z] (mill) 152 x 394 mm [d,h] (lathe)

Undercuts

Square profile, full radius, dovetail profiles

Radii : Depth

Depth must not exceed 12x drill bit diameter. For end mills, depth must not exceed 10x tool diameter.

Cost Saving Tip

To reduce costs, limit the number of part setups, the number of inspection dimensions or tight tolerances, and deep pockets with small radii.
