HIPS
High Impact Polystyrene
Rubber-modified polystyrene for impact-resistant sheet and mouldings.
01 Overview
HIPS is GPPS modified with polybutadiene rubber, trading optical clarity for a large gain in impact strength and toughness. It thermoforms cleanly and takes printing and decoration well, which makes it the standard choice for refrigerator liners, food service packaging and appliance housings.
02 Grades traded
- Sheet extrusion grades
- Injection moulding grades
- High gloss grades
- High impact grades
03 Typical specification
Melt flow rate
2 – 12 g/10 min (grade dependent)
Density
1.03 – 1.05 g/cm³
Izod impact
7 – 14 kJ/m² (grade dependent)
Appearance
Opaque natural pellet
Surface
High gloss grades available

07 Supply & export note
Impact grade selection should follow the forming depth and service temperature of the finished part; we will ask for both before quoting rather than defaulting to a mid-range grade.
