Consumable film Mooney Rheometer

Consumable films for a Moving Die Rheometer & Mooney are essential for preventing the rubber sample from sticking to the dies, ensuring easy cleanup, and obtaining accurate, repeatable test data 

Using the correct film is not just about convenience; it directly impacts the integrity of your test results.

• Film Thickness is Critical: The film sits between the sample and the dies, effectively becoming part of the test geometry. Variations in thickness can alter the die gap, a key parameter that influences the measured torque and thus the calculated viscosity and cure characteristics. Inconsistent film thickness leads to inconsistent data .

• Tear Resistance: During testing, especially at high strains, the lower film is subjected to significant stress as the dies oscillate. A film with poor tear resistance will rip, causing the rubber to contact the die directly, leading to slippage, contamination, and invalid results
