They offer a more sustainable alternative
to density modified grades that are based on
prime/virgin polymers.
These polymer formulations have been developed
to achieve equivalent performance to prime density
modified solutions with added sustainability
benefits.
Processing conditions can cause material properties to shift from the values stated in the information.
