Elongational Stress Tester

ISO11542-2:1998

Elongational Stress Tester 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, whose melt flow rate cannot be determined by the method specified in ISO1133 because of its extremely high molecular weight.

Features

• Six individual controllers, one for each station.
• 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. 
• Programmed test operation can realize the functions of automatic timing to release the brake rigging and automatic recording the test time.
• Tensile stress-time double logarithm curve can be plotted automatically, internal linear regression method can calculate the tensile stress F(150/10)automatically.
• Software is capable of plotting displace-time, temperature-time andtemperature-time curves, analyzing the tensile course, as well as saving and classifying test datum.
