LC-300A/D Melt Flow Indexer
The LC-300A/D Melt Flow Indexer is designed to measure both mass-flow rate (MFR) and volume-flow rate (MVR) of various polymers in their viscous flow state, suitable for engineering plastics such as PC, polysulfone, fluoropolymers and nylon, as well as polyolefins including PE, PS, PP, ABS and POM. It features a touchscreen display, a temperature range of 50–450°C, and an automatic & manual cutting method, delivering fast heating, low overshoot and stable temperature control for plastics manufacturing, petrochemicals, universities and inspection authorities.
Product Details
Applications：
This instrument is used to determine the melt flow rate of
This combined MFR/MVR tester measures both melt mass-flow rate and melt volume-flow rate in one unit, suitable for polyolefins, ABS, PC, nylon, fluoropolymers and other thermoplastics. Precision PID control ensures fast heating, low overshoot and stable temperature; the die and piston meet ISO 1133 and ASTM D1238 tolerances. Automatic and manual modes provide standardized sampling with good repeatability, and the instrument complies with GB/T 3682, ASTM D1238, ISO 1133 and JIS K7210.
Operating Conditions:
Installation environment: Free from vibration and corrosive media; installed on a solid foundation; free from strong magnetic fields and strong air convection.
The instrument consists of four parts: main unit, temperature control, temperature measurement, and automatic cutting.
Main Unit: Includes furnace, barrel, piston, die, and weights; extrudes the sample.
Furnace: Electric heating with temperature sensing.
Barrel: Alloy steel, corrosion-resistant; inner diameter Ф9.55±0.025 mm, length 160 mm.
Piston: Stainless steel, with ring marks for cutting; high dimensional accuracy and surface finish.
Die: Tungsten carbide, two inner diameters available; high inner-wall finish.
Load: Total weight of weights, tray, and piston; accuracy ±0.5%.
Pull-out Plate: Controls die installation and removal; does not obstruct sample flow during cutting.
Temperature Control: Room temperature to 300 ℃, accuracy ±0.2 ℃, fluctuation ±0.5 ℃.
