PP excels in chemical and moisture resistance and supports cost-efficient, high-volume production, while ABS offers better dimensional stability, machinability, and surface finish.
Use PP for lightweight, flexible, and chemical-resistant components, and ABS when rigidity, impact resistance, and aesthetics are priorities.
Choose PP for lightweight, chemical-resistant, and flexible components, and ABS when rigidity, impact resistance, and polished surface finish are priorities.
Before deciding which material fits your needs, it’s important to understand each in detail.
What is ABS Plastic?
ABS is an opaque thermoplastic made from three monomers: acrylonitrile, butadiene, and styrene. Manufacturers can adjust these monomers to create ABS with specific levels of rigidity, heat resistance, and surface finish, making it highly versatile.
ABS is commonly used in automotive interiors, electronics, household appliances, aerospace components, and medical devices. Its combination of strength, durability, and aesthetic flexibility makes it a top choice for both prototyping and large-scale production.
While ABS emphasizes rigidity and surface quality, polypropylene offers a different value proposition with lightweight, flexible, and chemically resistant characteristics.
Key Applications of ABS
ABS is ideal for parts that require dimensional stability, strength, and design precision:
Automotive Interiors & Exteriors: Dashboards, glove boxes, mirror housings, and grilles use ABS for its rigidity and polished surface finish.
Consumer Electronics: ABS is preferred for TV casings, remotes, and appliance shells due to impact resistance and electrical insulation.
Medical & Laboratory Equipment: Diagnostic devices, surgical instruments, and test kits rely on ABS for durability and precision.
Aerospace Components: Tray tables, seat backs, and instrument panels are manufactured with ABS for complex shapes and tight tolerances.
Household & Industrial Products: Mixers, vacuum cleaners, toys, and housings benefit from ABS’s visual appeal and mechanical strength.
Understanding ABS’s strengths is key, but it’s equally important to examine its limitations before making a material choice.
Advantages of ABS
ABS provides a strong combination of cost-effectiveness, durability, and versatility:
Affordable: Cost-effective for high-volume production and prototyping.
Rigid and durable: Maintains structural integrity under repeated use and moderate heat.

Limitations of Propylene
Polypropylene does have some limitations that must be considered for specific applications. Here are some:
Low melting point: Sensitive to high heat and open flames, limiting use in high-temperature environments.
Poor adhesion: Difficult to bond or paint without special surface treatments, increasing production steps.
Non-biodegradable: Requires proper recycling to prevent environmental harm.
Limited UV resistance: Prolonged sun exposure can degrade strength and color.
Dimensional changes: Semi-crystalline structure can cause shrinkage during molding, requiring careful design compensation.
