Flexible and semi‐rigid PVC formulations with high oxygen indexes and low smoke densities, as measured by the NBS Smoke Test (ASTM E662‐83) in both flaming and non‐flaming modes have been identified. The feasibility of a significant reduction of HCl emission from PVC compounds has been demonstrated in concept, and appears to be achievable when accompanied by increased oxygen index and/or significant reductions in rate of heat release and in smoke density, when measured in both the non‐flaming and flaming modes. PVC compounds, including those incorporating the kind of improvements outlined here for experimental prototypes, may be expected to compete in the future in both performance and price compared to other plastics materials.
