Long-Stroke Tensile Testing System for Vulcanized Rubber

Long-Stroke Tensile Testing System

Capable of Measuring Even Specimens with a Large Break Strain


A tensile test method for vulcanized rubber is stipulated in JIS K6251 (Rubber,vulcanized or thermoplastic-Determination of tensile stress-strain properties). One of the properties of vulcanized rubber is significant elongation. This long-stroke tensile testing system for vulcanized rubber has a long stroke that is required for calculating these tensile characteristics of rubber, and accommodates dumbbell specimens Nos.1 through 6 stipulated in JIS K6251.

This system is based on the Shimadzu Autograph AG Series, and consists of a "pantograph type grip" having outstanding operability, "SES-1000 Extensometer for Soft Materials" compatible with measurement of high ductility elongation, and the AG dedicated software "TRAPEZIUM2" for conducting data processing from the test force-displacement curve in real time.

This system enables you to efficiently obtain the tensile characteristics of vulcanized rubber.
