INEOS Styrolution 8265 Hot Sale HIPS Resin

Physical Properties

• Density: As per ISO 1183, the density is 1.04 g/cm³, a fundamental metric for assessing material consistency and suitability for specific applications.
• Shrinkage: Tested according to ISO 294, the shrinkage ranges from 0.4% to 0.7%, crucial data for predicting dimensional changes in molded components.
• Water Absorption 23°C Saturation: Measured via ISO 62, water absorption is 0.06%, indicating material resistance to moisture uptake under full immersion.
• Melt Index 200°C 5kg: Per ISO 1133, the melt index is 3.5 g/10 min, reflecting the material’s flow characteristics during high-temperature processing.
• Melt Index 200°C 5kg: Also per ISO 1133, the melt volume rate is 3.1 cm³/10 min, providing an alternative measure of flowability for precision molding.
• Bulk Density Without External Lubricant: By INTERNAL METHOD, bulk density 0.6 g/cm³ assesses material handling and storage needs.

Polymer Properties:

• Base Material: HIPS
• Modification Features:
  
  • Optimized for extrusion and thermoforming processes to create large, thin-walled parts.
  • HB flammability rating ensures safety in food packaging and appliance applications.
  • Good impact resistance and rigidity for refrigerator inner liners and thermoformed sheets.

Applications:

1. Refrigerator and Freezer Liners
   
   • This is the most significant application for INEOS Styrolution 8265.
   • The resin is specifically formulated to withstand the cold temperatures and constant exposure to food, oils, and cleaning agents found inside a refrigerator.
   • The high ESCR is a critical feature, preventing the liners from cracking or becoming brittle over time.
2. Food Packaging and Containers
   
   • The high ESCR and good low-temperature properties also make Styrolution 8265 a great choice for food packaging, particularly thermoformed trays and containers that hold fatty or oily foods.
   • It provides structural integrity and prevents potential leaks or cracks that could occur during shipping and handling.
3. General Extrusion and Thermoforming
   
   • Beyond refrigeration and food, Styrolution 8265’s balanced properties make it a solid choice for other extruded sheet and thermoformed products.
   • This includes products that may be exposed to chemicals or require a high degree of toughness.
