Used to determine the Melt Mass-Flow Rate (MFR) of various plastics and resins in a viscous flow state under specific temperature and load conditions, measured as the mass passing through a standard die every 10 minutes. It is suitable for high-melting-point engineering plastics such as polycarbonate, polyarylsulfone, fluoroplastics, and nylon, as well as lower-melting-point materials like PE, PS, PP, ABS resin, and POM. It is extensively applied in plastic production, plastic products, petrochemical industries, universities, research institutes, and commodity inspection departments.
Determination via the Melt Mass-Flow Rate (MFR) / Gravimetric Method.
- Dual-Language Display: Equipped with a color LCD screen supporting both Chinese and English interfaces.
- Integrated Cutting: Features both manual and automatic cutting modes in a single unit.
- Dual Temperature Control: Employs a dual heating/control system for superior precision and faster heating efficiency.
- Imported Dual Sensors: Features dual imported sensors to ensure an accurate temperature gradient between the upper and lower zones; sensors can operate independently for extended service life.
- Premium Materials: The barrel is made of imported Nitrided Hastelloy, and the die is crafted from tungsten carbide, ensuring robust durability and wear resistance.
- Stainless Steel Construction: The insulation barrel is constructed entirely from SUS304 stainless steel to prevent rusting under long-term high-temperature exposure.
- Automated Processing: Automatically calculates test results and provides a printed output.
