PP is a light, chemical-resistant plastic. We machine it into tough, safe parts.
Overview
PP is a light, chemical-resistant plastic. We machine it into tough, safe parts.
PP (Polypropylene) is a light, flexible plastic. It resists chemicals and fatigue and is easy to machine.
Computer-controlled mills and lathes cut a solid block into a precise part.
Tight-tolerance parts for prototypes or production, finished to your drawing.
Specifications
Typical reference values for PP (Polypropylene) through cnc machining. Final numbers can vary with grade and part shape.

| Manufacturing process | CNC Machining |
| Density | 0.90–0.91 g/cm³ |
| Tensile strength | 25–40 MPa |
| Service temperature | −20 to 100 °C |
| Standard finishes | Polishing, coating, texturing |
Values are typical reference data and may vary with grade, heat treatment, and part geometry. Tell us your needs and we will confirm exact specs.
Why PP
Stands up to acids, bases, and solvents.
Bends repeatedly without breaking.
One of the lightest plastics.
Approved for food contact.
Material Options
We stock common grades. Tell us your need and we will pick the right one.
Stiffer, stronger grade.
Tougher, more impact resistant.
Stronger and more stable.
How It Works
From your file to a finished part in five clear steps. Start with a free quote.
Upload your STEP or STL file and drawings. Get a clear, factory-direct quote with free DFM feedback, usually within 24 hours.
Our engineers check wall thickness, tolerances, and features. We suggest changes that save cost and improve quality.
We cut your part from a solid block with mills and lathes in our machine shop.
We remove burrs, then apply the finish you need, such as polishing or plating.
We measure and inspect each part, then pack and ship worldwide with full tracking.
Applications
Bend thousands of times.
Sterilizable, inert parts.
Chemical-proof fittings.
Light, chemical-proof trim.
Design Tips
New to this process? These simple rules help your part turn out well and cost less.
Keep walls thick enough to stay rigid. Thin areas can vibrate and warp during cutting.
Tight tolerances cost more. Only specify them where the function needs them.
Small chamfers and radii help tools last longer and parts look cleaner.
Finishes
The natural milled surface. Good for most functional parts.
A smoother, brighter surface for looks or low friction.
Nickel, chrome, or other coatings for corrosion or wear protection.
A chemical treatment that boosts corrosion resistance on some metals.
Why YiguProto
