Formosa TAIRIREX HP825S Hot Sale HIPS Resin

Physical Properties

• Density (23°C): Determined by ASTM D792 and ISO 1183, the density at 23°C is 1.04 g/cm³, consistent across standards for mass-to-volume ratio.
• Shrinkage (3.2mm): Per ASTM D955, shrinkage for 3.2mm-thick samples ranges 0.4–0.7%, indicating dimensional change during cooling or processing.
• Melt Index (200°C, 5 kg): ASTM D1238 and ISO 1133 both report 2.7 g/10min, showing uniform flowability measurement at 200°C under 5 kg load.
• Monomer Content: Residual monomer content is 500 ppm, a lower level impacting safety, stability, and compliance in material applications.

Polymer Properties:

• Base Material: High Impact Polystyrene (HIPS)
• Modification Features:
  
  • Suitable for extrusion molding with stress crack resistance.
  • High tensile strength and heat distortion temperature.
  • Odorless with low monomer residue, meeting HB fire rating.

Applications:

• Refrigerator Liners and Door Panels
  
  • This is one of the most prominent applications for TAIRIREX HP825S. The resin is specifically formulated to withstand the cold temperatures inside a refrigerator and freezer without becoming brittle.
  • Its toughness prevents cracking and breakage from daily use, such as the impact of food items or repeated opening and closing of doors.
• Automotive Interior and Trim Parts
  
  • The automotive industry uses TAIRIREX HP825S for various interior components, such as door liners and other trim parts.
  • Its balance of stiffness, impact resistance, and dimensional stability makes it a reliable choice for these non-structural applications.
• Extruded Sheets and Profiles
  
  • TAIRIREX HP825S is well-suited for extrusion processes to produce sheets and profiles. These can then be used in a variety of other applications, including signage, point-of-sale displays, and other formed products.
