Thanks to thermoplasticity, the molding process is reversible and can be theoretically repeated many times without chemical modification of the materials
SEPS/SEBS based TPE is a better alternative to PVC for:
For our health (for workers and end-user: phthalates free), so it has been widely used in producing the anesthesia mask, artificial resuscitation bag etc.
For environment (PVC can be recycled with some complications due to the poor thermal stability)
For processing (corrosion)
Has a better flexibility at low temperature
Better performance with high temperature (better compression set)
Has a lower density (decrease material quantities)
Has a high compatibility with PP and many other polyolefinic polymers
Substitution easy if the key point is: cleanes, softness, transparency, odourless
Substitution not easy if the key point is: COST
