Elongation Stress Tester
Standards
ISO 11542-2:1998
GB/T21461.2-2008
Application
EST is designed to determine the elongational stress of ultra high molecular weight Polyethylene (PE-UHMW) molding and extrusion material. The elongational stress is a characterization of the melt viscosity of PE-UHMW moulding powder.
Features
◆ 6 individual controllers, one for each station;
◆ High efficiency, may successfully obtain the tensile stress with only one test.
◆ Unique lift structure makes the specimen support performance stably, also extends operating space.
◆ Automatic smoke exhaust system provides a good test environment.
◆ Temperature protective system runs independently of the controlling system, is designed to prevent the test temperature not exceed the limit point.
◆ Tensile stress-time double logarithm curve can be plotted automatically, internal linear regression method can calculate the tensile stress F（150/10） automatically.
