WebbDynamic mechanical analysis (DMA) measures the mechanical properties of polymeric materials as a function of temperature, time, frequency, stress, or a combination of these parameters. Different clamping geometries are available to enable samples to be tested in different deformation modes (i.e. bending, tension, compression, torsion and shear). Webb7 juni 2024 · Selection of a suitable thermal aging process could render desirable mechanical properties of the rubbers or blended rubbers. In this work, the effect of the aging processes on the mechanical properties and activation energies of natural rubbers (NR) and NR/chloroprene rubbers (CR) blends with low CR contents …

WebbThis part of ISO 4664 provides guidance on the determination of dynamic properties of vulcanized and thermoplastic rubbers. It includes both free- and forced-vibration methods carried out on both materials and products. It does not cover rebound resilience or cyclic tests in which the main objective is to fatigue the rubber. 2 Normative references WebbElastomeric Rubber Foam. Polyurethane foam.
