Abstract
An extensional rheometer comprises a rotatable primary wind up drum and one or more secondary rotatable windup drums wherein a sample is attached to the primary windup drum and each secondary windup drum. Counter rotation of the primary windup drum and each secondary drum causes each affixed sample to stretch until rupture. The load response on each primary and secondary windup drum set caused by a stretching sample is measured with a load sensing device. Environmental control may be provided for testing samples under different conditions.
