TPE Quick Facts
• How are TPEs made?
TPEs:
The Basics
What are TPEs?
To help you identify
the right materials for your product, they will need to know:
1. the kind of environment in which your product will be used
2. what kind of properties you need (e.g., stretchy, hard or soft, color)
Is TPE the best material for my products?

TPEs vs.
One caveat: Typical TPE shrinkage is around 2% while that of substrate materials
is closer to 1%.
When looking to incorporate sustainable content into your TPE, the raw
material cost may be more expensive than traditional materials for three
reasons 1) supply chain maturity, 2) high demand, low supply, 3) location
of source and supplier.

Specifically, here are five ways TPEs can help the
healthcare industry meet an anticipated capacity
crunch:

Known for offering tight seals and reducing
vibration and noise, certain thermoplastic elastomers
(TPEs), like OnFlex™ grades, may be better suited
for your particular application than the historically
incumbent materials, like general purpose TPEs,
thermoplastic vulcanizates (TPV), and thermoplastic
polyolefins (TPO).
