Product Introduction
GBB‑R Melt Flow Index Tester is a precision testing instrument for packaging materials, developed and manufactured by GBPI R&D team in accordance with ISO, GB standards and market demands. It is used to determine the melt mass‑flow rate (MFR) and melt volume‑flow rate (MVR) of thermoplastic plastics.
It is suitable for measuring melt flow index under high‑temperature conditions of various polymer raw materials, including polyethylene, polystyrene, polypropylene, ABS resin, polyoxymethylene resin, polycarbonate, nylon and fluoroplastics. It is an ideal instrument for offline or online detection of melt flow index of thermoplastics in plastic raw material production, plastic products, petrochemical and other industries.
Test Principle
Under specified temperature and load conditions, the molten material extruded through a die of defined length and diameter is used to calculate the melt mass‑flow rate (MFR) and melt volume‑flow rate (MVR).
