MFi-6F Melt Flow Indexer
The MFi-6F Melt Flow Indexer is designed for testing fluoropolymers and high-temperature engineering plastics. Its barrel and piston are made of fluorine-resistant material, with a dual-zone temperature control system. It supports MFR, MVR and die-cutting tests with automatic weighing and timing, suitable for performance testing of fluorine-containing materials such as PTFE, PFA and FEP under high-temperature corrosive conditions. It offers a test temperature range of 50–450℃ and a weighing range of 0–320g.
Product Details
Product Introduction：
The MFI-6F Fluoroplastic Melt Flow Index Tester is a dedicated extrusion plastometer designed for fluoropolymers and high-temperature engineering plastics. Its corrosion-resistant cylinder and piston rod, together with an independent dual-zone temperature control system covering 50°C to 450°C with a stability of ±0.2°C, ensure reliable testing of PTFE, PFA, FEP and other fluorine-containing materials under harsh high-temperature and corrosive conditions. With a compact structure and an intuitive interface, the instrument is suited to production control, quality inspection and material R&D.
The instrument supports mass-flow-rate measurement (MFR), volume-flow-rate measurement by timing (MVR) and half-die testing, with automatic weighing and timing across an MFR range of 0.01–200 g/10min. The 7-inch touchscreen offers a bilingual Chinese/English interface, a timing resolution of 0.001 s and a 50.00 mm displacement stroke. Combined with manual and automatic cutting modes, a USB data port and an erosion-resistant tool holder, it delivers standardized, traceable test results for material grading and process optimization.
Dual-Zone Control, Stable MFR & MVR Testing
The MFi-6F is a fully automatic melt flow index tester specially designed for high-temperature and corrosive materials such as fluoroplastics. Its key components in contact with the melt — including the barrel and piston — are made of fluorine-resistant materials. Combined with a dual-zone temperature control system and electric loading structure, the instrument provides stable MFR and MVR tests over a wide temperature range of 50℃ to 450℃, ideal for PTFE, FEP, PFA, PVDF and other fluoropolymers as well as general engineering plastics.
Built for Fluoropolymers · Precise and Reliable
Purpose-built for fluoropolymers and high-performance engineering plastics, the MFi-6F ensures consistent, reproducible melt flow characterization. Its fluorine-resistant melt-contact components prevent adhesion and sample contamination, while the dual-zone heating system maintains a uniform thermal profile throughout the test cycle. Suitable for both quality control and R&D laboratories, the instrument offers flexible test methods and reliable data traceability, supporting confident material processability evaluation and efficient daily melt flow testing.
