If you're in product design, engineering, or procurement, chances are you've had to choose between Polypropylene (PP) and Acrylonitrile Butadiene Styrene (ABS) at some point. Both are versatile thermoplastics, each with strengths that make them suitable for different use cases. In this article, we’ll take a practical look at how these two materials compare—based on real-world performance, processing, and typical applications—so you can make confident, informed decisions.
Polypropylene is a lightweight, semi-crystalline thermoplastic that’s widely used across industries for its chemical resistance, fatigue strength, and cost-effectiveness. It’s often the first choice for parts where flexibility and durability matter more than stiffness.
Very low density, ideal for weight-sensitive designs
Excellent resistance to chemicals and moisture
Good fatigue resistance, especially in hinge-style features
Easy to process and mold
Budget-friendly for high-volume production
Common Applications: packaging components, labware, battery casings, closures.
ABS is a tough, impact-resistant thermoplastic prized for its strength, rigidity, and high-quality surface finish. It's commonly used in products that need to look good and hold up under stress.
Strong and rigid, ideal for structural applications
Excellent surface appearance—easy to paint, plate, or texture
Consistent dimensional stability
Withstands moderate heat and mechanical loads
Common Applications: electronics housings, automotive interiors, toolboxes, LEGO® bricks.
| Property | Polypropylene (PP) | ABS |
|---|---|---|
| Density | Lower (0.90 g/cm³) | Higher (1.04 g/cm³) |
| Impact Resistance | Moderate | High |
| Chemical Resistance | Excellent | Moderate |
| Surface Appearance | Matte, utility-grade | Smooth, premium finish |
| Flexibility | High | Low |
| Cost | Lower | Slightly higher |
| Heat Resistance | Up to 100°C | Up to 80°C |
Choosing between PP and ABS isn’t about which is “better”—it’s about what your product needs to do.
Choose Polypropylene if: chemical resistance is critical, you need a lightweight and flexible solution, or you're working within tight budget constraints.
Choose ABS if: your application requires rigidity, a clean surface finish, or high impact durability.
