1. The UR-2010SD’s upper and lower die cavities feature a rubber seal that maintains the pressure inside the dies while testing. This model is typically referred to as a MDR rheometer.
2. A. UR-2010 does not include a seal, but rather uses excess rubber from the specimen to seal the die cavity’s internal pressure.
B. The UR-2010 features a larger die cavity and therefore requires more time for heating, more suitable for the slowly curing products.
3. Both models are in compliance with ASTM D5289, ISO 6502, JIS K6300-2 and GB/T 16584.
4. Auto-cailbration of loss angle in both models.
