Description
Product Introduction: HD4850 High Density Polyethylene
Manufacturer: Jam Petrochemical Company
A professional-grade resin for fast, precise and high-performance manufacturers.
Jamlene HD4850 (HMI50) is a high-quality product from Jam Petrochemical, produced using Spherilene gas-phase technology. This means molecular-level control, stable output, uniform quality and consistent processing performance. Designed specifically for thin-wall injection molding, this grade has proven in practice to be a reliable choice wherever speed, accuracy and high flow are essential.
Key Features of HD4850 High Density Polyethylene
Exceptional flowability for fast production
With a Melt Index of 50, injection shots are completed at a speed many other grades cannot match. This resin is designed for production lines where every second matters.
Strong impact resistance even at low temperatures
HD4850 High Density Polyethylene maintains impact performance at room temperature and down to minus 18°C, making it ideal for freezer containers, cold-chain packaging and products exposed to low-temperature environments.
Smooth surface and trouble-free production
Its narrow molecular weight distribution results in:
- Complete filling of complex molds
- Reduced risk of weld-line defects
- Improved surface appearance
- Consistent quality over long production cycles
Stabilized with standard additives
Thermal antioxidants and catalyst neutralizers help ensure stable behavior during processing and preserve product quality.
Applications: Where This Resin Truly Excels
1. Thin-wall containers
Perfect for applications requiring minimal wall thickness, high injection speed and uniform mold filling. HD4850 performs exceptionally in thin-wall packaging.
2. Food containers and freezer-grade packaging
Thanks to its excellent low-temperature resistance, HD4850 is ideal for:
- Ice cream containers
- Ready-meal packaging
- Frozen food packaging
- Refrigerator and freezer-safe containers
3. High-speed injection molded parts
Factories with continuous, rapid-cycle production benefit from HD4850’s high flow, which increases output and reduces cycle times.
4. Caps, lids and small injection parts
Lightweight parts requiring fast mold filling are efficiently produced with HD4850, minimizing short-shot defects.
5. Compounding and masterbatch production
Its stable behavior and high flowability make it an excellent base resin for masterbatch production, filled compounds and lightweight engineering grades.
In short:
Wherever thin walls, high speed, clean appearance and reliable cold-temperature performance are required, HD4850 High Density Polyethyleneis a practical, efficient and professional choice.
