Materials Guide
Styrene
Styrene is a lightweight, economical thermoplastic often selected for its ease of processing and cost efficiency. While not as durable as engineering plastics, it offers good rigidity for applications where affordability and simplicity are key.
What is Styrene?
Styrene polymers are derived from styrene monomers and can be processed into various forms such as general-purpose polystyrene (GPPS) or high-impact polystyrene (HIPS). These variations allow for different balances of rigidity, impact strength, and surface finish.
Common Applications
Styrene is widely used for:
- Point-of-purchase displays and signage
- Packaging and disposable products
- Appliance and electronics housings
- Lightweight construction profiles
- Consumer goods and toys
Fun Fact: Styrene was first discovered in tree sap! The resin from the oriental sweetgum tree naturally contains styrene — making it one of the few plastics with roots in nature.
Important Considerations
Benefits
- Excellent processability and cost efficiency
- Good rigidity and dimensional stability
- Smooth surface finish suitable for printing or coating
- Lightweight and easy to fabricate
- Available in GPPS & HIPS grades for different performance needs
Limitations
- Lower impact resistance than engineering plastics
- Limited heat and UV resistance without additives
- Can become brittle under low-temperature impact
- Not suitable for heavy structural or load-bearing applications
