Polypropylene vs Polycarbonate vs ABS: Which Suitcase Material Wins?
Hardside suitcases are manufactured from three primary polymers: Polypropylene (PP), Polycarbonate (PC), and ABS plastic. Understanding the physical properties of these materials ensures you buy a suitcase that won't crack or weigh you down.

1. Material Science Breakdown
| Characteristic | 100% Virgin Polypropylene (MYKASE) | Polycarbonate (PC) | ABS Plastic |
| :--- | :--- | :--- | :--- |
| Material Density | 0.90 g/cm³ (Lightest luggage material) | 1.20 g/cm³ (30% heavier) | 1.05 g/cm³ |
| Impact Elasticity | Flex-memory absorbs drop shock & pops back | High rigidity | Low elasticity (Prone to cold cracks) |
| Cabin Weight (55cm) | 2.9 kg (45L capacity) | 3.2 kg - 3.6 kg | 3.4 kg - 3.8 kg |
| Scratch Resistance | High (Textured satin & matte finish) | Moderate (Gloss PC scratches easily) | High initial finish, deep scratches |
| Water Resistance | 100% Waterproof non-porous surface | Water-resistant | Water-resistant |

2. Why 100% Virgin Polypropylene is Superior
- Unbreakable Flex-Memory: Virgin Polypropylene absorbs kinetic energy from heavy baggage drops by flexing inward and immediately restoring its shape.
- Maximum Packing Efficiency: At only 2.9 kg empty weight for a 55 cm cabin bag, PP saves up to 1 kg of empty weight compared to polycarbonate, letting you pack more clothing within strict 7 kg airline weight caps.
- Weather Protection: Non-porous water-resistant construction protects your clothes during heavy monsoons and tarmac rain exposure.

3. Essential Features to Look For
In addition to 100% Virgin PP shell tech, MYKASE suitcases integrate:
- 360° Silent Dual Spinner Wheels: Smooth, strong, rugged dual rubber wheels for whisper-quiet gliding across cobblestones and tarmac.
- Anti-Theft Double Coil Zippers: Premium quality zips resistant to pen puncture attacks.
- Flush TSA Lock: Built-in 3-digit combination security.
