KINGFA HIPS-5197
- High impact HIPS
- 10 kJ/m² toughness
- Low shrinkage 0.4–0.7%
- UL94 HB rated
- Excellent electrical insulation
- Ideal for appliance and electrical housings
Product Overview
KINGFA HIPS-5197 is a high-impact polystyrene (HIPS) engineered for injection molding applications.
This grade delivers a strong balance of toughness, dimensional stability, electrical insulation, and flame performance, making it particularly suitable for home appliances, electrical enclosures, and structural casings.
With 10 kJ/m² impact strength, low shrinkage (0.40–0.70%), and UL94 HB rating, HIPS-5197 provides reliable mechanical performance while remaining easy to process in high-volume manufacturing environments.
Key Properties
High Impact Resistance – 10 kJ/m² notched Izod
Low Shrinkage (0.40–0.70%) – excellent dimensional stability
Flame Performance – UL94 HB across multiple thicknesses
Excellent Electrical Insulation – volume resistivity 1.0E+16 Ω·cm
Good Processability – MFR 5.0 g/10 min for stable injection molding
Typical Applications
Appliance housings – washing machines, air conditioners, refrigerators
Electrical enclosures – switch boxes, instrument casings
Consumer product casings – printers, small electronics, equipment shells
General structural parts – impact-resistant components
