INEOS Styrolution 4241 Hot Sale HIPS Resin

Physical Properties

• Density: As per ISO 1183, the material density is 1.04 g/cm³, defining its mass-to-volume ratio under standard conditions.
• Shrinkage: Tested via ISO 294, shrinkage ranges 0.4–0.7%, indicating dimensional change during molding for typical applications.
• Water Absorption (23°C Saturation): ISO 62 specifies 0.07% water absorption, showing high moisture resistance for humid environments.
• Melt Index (200°C, 5 kg – Mass Flow): ISO 1133 reports 3.5 g/10min, measuring mass flow rate during heating for processability assessment.
• Melt Index (200°C, 5 kg – Volume Flow): ISO 1133 shows 3.4 cm³/10min, providing volume-based flow data for extrusion or injection molding.
• Bulk Density (Without External Lubricant): An internal method gives 0.6 g/cm³, reflecting the material’s loose packing density without additives.

Polymer Properties:

• Base Material: High – Impact Polystyrene (HIPS)
• Modification Features:
