Physical Properties Chart
The range of properties that can be developed for any given polymer is limited by
the material itself, and will vary within that range with compound formulation.
All properties in a particular class are not found in a single compound. However,
it is often possible to raise or lower some ratings to acceptable levels through
creative compounding.
