PanJin HIPS 825 | High Quality & Stable Supply for Various Applications
Product Overview
PanJin HIPS 825 is high impact polystyrene (HIPS) produced by Liaohua Panjin Ethylene Plant. It is modified polystyrene blended with rubber segments, featuring balanced rigidity and outstanding anti-drop performance. It is a mainstream injection molding grade widely used for home appliance shells, toy parts, daily packaging and automotive interior components. Stable batch performance and consistent supply make it the preferred raw material for many mass-production factories.

Core Product Advantages
Stable impact resistance
PanJin HIPS 825 adopts stable graft copolymerization technology. Internal rubber phases disperse evenly. Finished parts do not crack easily during falling or extrusion demolding. It solves the common brittle defect of ordinary GPPS, suitable for products that require daily anti-collision performance such as toy shells and electrical enclosures.
Steady batch consistency
Strict online monitoring controls MFR fluctuation within ±0.5. Factories do not need frequent machine parameter adjustment after switching batches. Less defective products caused by inconsistent melt fluidity, cutting mold trial costs effectively.
Good injection processability
Moderate melt flow enables smooth mold filling for thin and medium-thickness parts. The finished surface has uniform gloss without obvious flow lines or silver marks. It matches single-color injection and structural foaming production lines, with a wide adjustable temperature range.
Complete industrial matching
One grade covers daily goods, electronics, toys and automotive inner plastic parts. Factories can reduce reserved resin types, lower warehouse occupancy and relieve capital pressure. Long-term mass supply avoids production shutdown risks caused by raw material shortage.
Main Application Fields
- Home appliance housings: TV shells, air conditioner internal parts, small electrical casings
- Toy & daily consumer goods: Plastic toys, cosmetic outer boxes, stationery shellsPackaging & printing: Rigid plastic packaging boxes, disposable instrument shells
- Automotive interior parts: Car small interior decorative components, storage trays
- Structural foaming parts: Lightweight buffer plastic frames
Processing & Storage Guidelines
Pre-drying suggestion: Dry at 70–80℃ for 1–1.5 hours if pellets absorb moisture after long-term opening, to eliminate silver streaks.
Recommended injection temperature: Rear barrel 170℃, middle barrel 185℃, front barrel 195℃, nozzle 190℃
Mold temperature: 40–60℃; keep sufficient vent slots to avoid burn marks
Storage rules: Keep warehouse dry and ventilated, stay away from direct sunlight and heat sources. Seal original bags to prevent dust and impurity contamination.
