ChronoThane P™ 55D
TPU(热塑性聚氨酯)
AdvanSource Biomaterials(美国ASB)
产品描述
ChronoThane P is a family of aromatic ether based polyurethane elastomers. With a long history of reliable performance, this medical grade polymer has the versatility to be used across a broad range of applicational areas including catheters, ports and access devices.
These biocompatible materials possess characteristics such as low coefficient of friction, low extractables, dimensional stability, high impact resistance, and excellent tear strength.
ChronoThane P allows for ease of manufac- turability and can be processed using conven- tional extrusion or injection molding equipment. These materials are available in hardnesses ranging from 75 Shore A to 75 Shore D.
