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. http://www.art.canaco.org https://www.avient.com/sites/default/files/2020-11/gls-acqua-plose-case-study.pdf 1http://store.elsevier.com/Handbook-of-Polymer-Applications-in-Medicine- and-Medical-Devices/isbn-9780323221696/ Tear Resistance PERFORMANCE COMPARISON In Handbook of Polymer Applications in Medicine and Medical Devices,1 Laurence W.
