SRZ-400H Melt Flow Rate Tester
Product Introduction
The SRZ-400H Melt Flow Rate Tester is a high-precision MFR and MVR testing instrument designed for measuring the melt flow properties of thermoplastic materials. The instrument complies with GB3682-2018 requirements for mass method MFR and volume method MVR testing, while key parameters meet the requirements of ISO1133-2011 standards.
The SRZ-400H melt flow index tester is widely used for evaluating the melt flow rate of polymers including polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS, polyamide, fiber resin, acrylic resin, polyoxymethylene (POM), fluoroplastics, and polycarbonate (PC).
With touchscreen operation, high-accuracy temperature control, automatic cutting positioning, and intelligent calculation functions, the SRZ-400H provides reliable test data for polymer research, material development, and quality control.

• Wide application range
Suitable for various thermoplastic polymers and research-grade material evaluation.

Working Principle
The SRZ-400H melt flow rate tester determines polymer flow characteristics by measuring the amount of molten material flowing through a standard die under specified temperature and load conditions.
The testing process:
1.A polymer sample is placed into the heated barrel.
2.The sample is melted at a preset temperature.
3.A specified load is applied through the piston.
4.The molten polymer flows through the standard capillary die.
5.The instrument measures:
• MFR (Melt Mass Flow Rate): mass of material flowing per unit time (g/10 min or g/min)
• MVR (Melt Volume Flow Rate): volume of material flowing per unit time
The automatic cutting system periodically cuts extruded samples, ensuring consistent sample weight and improving repeatability.
