Rubber and rubber products. Determination of biobased content – General principles and calculation methods using the formulation of the rubber compound
| Published By | Publication Date | Number of Pages |
| BSI | 2017 | 24 |
This document specifies the general principles and the calculation methods for the determination of biobased content in rubber and rubber products, including polyurethanes, by using the compound formulation. These calculation methods are based on the mass or the carbon mass of each constituent present in the rubber or rubber product.
