But to do so, they needed to find a material that could deliver a fast reaction time -- a runner’s foot-strike time is 40-50 milliseconds from heel to toe – and the ability to both absorb energy and offer top-notch energy return properties.

Avoid the use styrenic materials – Low shrinkage
PP grades provide an ABS alternative.
Utilize existing molds – Replace current ABS
solutions with low shrinkage PP grades and utilize
your existing molds

They include amorphous polymers such as polystyrene (PS), High Impact
Polystyrene (HIPS), Polycarbonate (PC), Acetal (POM), PC/ABS, Acrylonitrile Butadiene Styrene (ABS),
Polyphenylene oxide (PPO), Noryl® (a miscible blend of PS and PPO), and PC/PETG.
For PC, ABS and PC/ABS, the adhesion values are plotted in Figure 8.

Today there is phenomenal interest in overmolding TPEs onto rigid substrates, particularly in the consumer
product arena in applications requiring a soft touch.
