Overview:
Gibitre MD Rheometer measures the cure characteristics of a rubber compound in conformity with the international standards.
The measure of the vulcanisation is carried our by measuring the change in the mechanical characteristics of the sample. The instrument permits to apply a cyclic strain to a test piece and to measure the associated force. The test is carried out at a constant temperature and the measure of stiffness recorded continuously as a function of time.
Standards the instrument complies with
ISO 6502; ASTM D 5289, 6204; DIN 53 529-3
Numerical Test Data (for each test procedure up to 20 test results can be selected)
Torque Values: MI, ML, M90, MX, MH, PCR, S’’@ML, S"@MH, TanD@ML, TanD@MH, G’@ML, G’@MH, G’’@ML, G’’@MH (X=customer-defined) Scorch Time: tS1, tS2, tSX (X=customer defined) Cure Time: t90, tX, tML, tMH, tPCR, tRX (X=customer-defined)
