Equipment Principle and Purpose
Under specified temperature, load and piston-position conditions, the tester measures the timed rate at which molten material passes through a capillary die.
Melt flow index reflects high-temperature flow behavior and processability, supporting material selection, product development and process improvement.
Specifications and Test Standards
The GOTECH GT-7100-MI complies with ASTM D1238, GB/T 3682, ISO 1133 and JIS K7210.
Its temperature range is ambient to 450°C with dual PID control accurate to ±0.1°C. The flow-rate range is 0.15–50 g/10 min, and the cutting interval is adjustable from 0.1 to 999.9 seconds.
Material Selection and Standards Compliance
The tester accommodates different plastics and polymers for comparative evaluation of melt behavior.
Standardized testing helps verify compliance with relevant industry requirements, reduce application risk and improve market conformity.
