GPPS STL 525
$ 1.xxx / MT
GPPS STL 525 is a General Purpose Polystyrene (GPPS) grade, typically produced for applications requiring high transparency, good rigidity, and easy processability.
It is a crystal-clear, amorphous thermoplastic with low density and excellent dimensional stability, commonly used in injection molding and extrusion processes.
Packaging: 25Kg/ bag
Sold by container only: 28.00 MT/Container. Quantity = number of containers.
Description
Key Properties
- High transparency → Excellent optical clarity and gloss
- Good stiffness → Rigid structure, maintains shape well
- Easy processing, making it suitable for high production efficiency due to its low melt viscosity.
- Good dimensional stability → Low shrinkage during molding
- Low impact resistance → Brittle compared to HIPS or ABS
- Good electrical insulation properties
Typical Characteristics (General GPPS Range)
- Density: ~1.04 – 1.06 g/cm³
- Melt Flow Index (MFI): Medium to high (depends on grade, STL 525 is usually medium flow)
- Vicat Softening Temperature: ~90 – 100°C
- Transparency: Excellent (glass-like clarity)
