What’s the difference between PS sheets and acrylic

The key differences between PS sheet (polystyrene) and acrylic are as follows:
**Material**: PS is polystyrene, while acrylic is PMMA (polymethyl methacrylate).
**Transparency**: Acrylic has a higher light transmittance of 92% compared to PS, which ranges from 88-90%.
**Strength**: Acrylic is more impact-resistant, whereas PS is more prone to cracking.
**Weather Resistance**: Acrylic is UV-resistant, making it ideal for outdoor use over extended periods. PS, on the other hand, tends to yellow and deteriorate with time in outdoor conditions.
**Applications**: Acrylic is commonly used in advertising light boxes, while PS is preferred for disposable packaging.
In summary, the differences between PS and acrylic lie in their material properties and appropriate applications. PS, with its low cost and ease of processing, is suitable for short-term use in packaging or indoor decorations due to its lower impact resistance and tendency to yellow over time. Acrylic, with its superior transparency, weather resistance, and UV protection, is ideal for outdoor applications where durability is crucial, such as advertising signs and light boxes.
