Standard Test Method for Rubber Property—Plasticity and Recovery (Parallel Plate Method)

Importancia y uso:

4.1 The plasticity number and the recovery of the test specimen are related to the flow properties and the elastic properties, respectively, and may be useful in predicting processing characteristics, such as ease of forming and extrusion characteristics.

4.1.1 In this test method, plasticity is measured in an inverse manner, as noted by the final height of the specimen. Thus, high plasticity rubbers (high degree of flow during test) are indicated by a low plasticity number.
