Product Description

Oscillating Disc Rheometer

In this method, a specimen of compounded rubber is contained in a sealed test cavity under a positive pressure and maintained at an elevated temperature. A biconical disk is embedded in the test specimen and is oscillated about the shaft axis through a small are. This action exerts a shear strain on the test specimen and the force at maximum amplitude (torque) required to oscillate the disk is proportional to the stiffness (shear modulus) of the rubber. This torque is recorded autographically as a function of time

Graphics including Elastic torque; Cure rate; and Upper/Lower dies temperatures. Data; such as ML; MH; TS; TC; CRI etc.; can be taken from each test. Cure curve provides the processing; vulcanizing; and vulcanized physical properties of rubber cross-linking reaction. Multiple control gates are available for controlling the specified data such as ML; MH; TS; and TC. Standard accessory - SPC (Statistical Process Control) software is used to analyze and draw the statistical control charts including X-RM; -R; histogram; and normal distribution for some specified data.

Applicable Standards

ASTM Standards: ASTM D2048& ISO 6502
