The melt flow index tester (Extrusion Plastometer Series) manufactured by Bayerteq is an advanced material characterization instrument designed to determine the Melt Mass-Flow Rate (MFR) and Melt Volume-Flow Rate (MVR) of thermoplastic polymers. Built in rigorous compliance with global rheological standards including ISO 1133 (Parts 1 & 2), ASTM D1238, and ASTM D3364, this versatile testing line serves as the foundational quality assurance benchmark for resin manufacturers, compounders, masterbatch producers, and plastic pipe extruders worldwide.
Melt flow rate reflects the molecular weight, melt viscosity, and overall processability of polymer materials under standardized thermal and shear stress conditions. Whether assessing standard polyolefins (HDPE, LDPE, LLDPE, PP), engineering resins (POM, ABS, PA, PET), or high-temperature fluoropolymers and polycarbonates melting up to 450 °C, the Bayerteq melt flow index tester delivers precise, repeatable rheological data. The apparatus automatically computes MFR (g/10 min), MVR (cm³/10 min), melt density, and Flow Rate Ratio (FRR) across multiple standard weight loads.
Melt Flow Index Tester Series & Automation Architecture
Bayerteq provides a tiered hierarchy of plastometers tailored to laboratory throughput, from manual verification to fully hands-off robotic operation:
- MFI 450 Series (Manual & Motorized): Cost-effective benchtop workstations equipped with manual or motorized weight lifting, automatic timed cutting, and digital touch interfaces for routine incoming resin acceptance.
- MFI Galaxy 600 Series (High-Throughput Motorized): Features a high-definition 10.1-inch color touchscreen, motorized load application, high-resolution optical displacement tracking (±0.02 mm), and wide MVR measurement range up to 3000 cm³/10 min.
- MFI Galaxy 700 & 800 (Semi & Fully Automated Flagships): Equipped with automated pneumatic weight selector magazines (eliminating manual handling of heavy 21.6 kg stacks), instrument-controlled pre-compacting, automatic residue purging, and robotic barrel cleaning.
- Thermal Stability & Moisture-Sensitive Testing: Dual-zone heating sleeves provide thermal stability within ≤0.2 °C up to 450 °C with 0.01 °C resolution, fully certified for ISO 1133-2 testing of moisture-sensitive and time-temperature dependent polymers.
- Comprehensive Data Management (DMS): Stores over 5,000 complete test curves internally with USB export, multi-tier user permissions, and bidirectional PC communication for LIMS integration.
From quality verification of pipe extrusion pellets to advanced polymer synthesis, this melt flow index tester ensures compliance and precision.
