ChronoThane T™ 93A – B40
TPU(热塑性聚氨酯)
AdvanSource Biomaterials(美国ASB)
产品描述
ChronoThane T is a family of aliphatic ether based polyurethane elastomers.
These biocompatible materials possess characteristics such as low coefficient of friction, low extractables, dimensional stability, high impact resistance, and excellent tear strength.
ChronoThane T can be tailored to meet specific Melt Flow Index ranges to suit your manufacturing or extrusion processes.
These materials are available in hardnesses ranging from 75 Shore A to 75 Shore D.
