The plasticity of natural rubber is measured using a Plastimeter. The plasticity is measured by compressing a small sample under a known load for a set amount of time. An important measurement is the Plasticity Retention Index (PRI), which used to give an indication of the oxidation resistance of raw natural rubber at a specified temperature.up to 99% rubber hydrocarbon, while natural rubber is usu-ally around 93% rubber hydrocarbon and molecular weight distribution of natural rubber is widely variable [1]. Some of the non-rubber substances such as lipids, caro-tenoid pigments, sterols, triglycerides, glycolipids and phos-pholipids can influence the final properties of rubber, such asBy means of two circular parallel platens, precise deflection sensor, accurate temperature detection & control system, this EKT-2003RP RAPID PLASTIMETER will measure the plasticity of raw rubber material especially natural rubber under the condition of specified testing temperature as defined by international standards.
plasticity testing
In physics and materials science, plasticity (also known as plastic deformation) is the ability of a solid material to undergo permanent deformation, a non-reversible change of shape in response to applied forces. [1] [2] For example, a solid piece of metal being bent or pounded into a new shape displays plasticity as permanent changes occur within the material itself. A low elastic modulus is typical for materials that are easily deformed under a load; for example, a rubber band. If the stress under a load becomes too high, then when the load is removed, the material no longer comes back to its original shape and size, but relaxes to a different shape and size: The material becomes permanently deformed.A low elastic modulus is typical for materials that are easily deformed under a load; for example, a rubber band. If the stress under a load becomes too high, then when the load is removed, the material no longer comes back to its original shape and size, but relaxes to a different shape and size: The material becomes permanently deformed .Plasticity Retention Index (PRI) PRI is a measure of the resistance of raw natural rubber to oxidation. The oxidation effect is assessed by measuring the plasticity before ageing (P0) and after ageing for 30 mins in the MonTech ageing oven for Plasticity testing at 140°C (P30) (PRI = (P30/P0)x100) Working Principle

2.4.2. Atterberg Limits. The Atterberg limits are a basic measure of the nature of a fine-grained soil.Depending on the water content of the soil, it may appear in four states: solid, semi-solid, plastic and liquid. In each state the consistency and behavior of a soil is different and thus so are its engineering properties.the instantaneous distribution of the chain vectors cannot be affine in the strain escaped notice for many years. The copious interpenetration of chains that characterizes polymer networks should be
