ChronoThane T

VERSATILE AND EFFECTIVE; STRONG DIMENSIONAL CONTROL THROUGH EASE OF MANUFACTURABILITY. 

Aliphatic Polyether-Based Urethanes

 

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.

ChronoThane T processing can be optimized by drying to a moisture content equal to or less than 0.05% by weight prior to melt processing.  

Typically, the pellets must be dried for 3-4 hours with a dryer inlet air temperature of 180ºF +/- 20ºF. We recommend a machine-mounted desiccant-type hopper dryer, capable of reaching and maintaining a dew point of -40ºF.  If dry times are in excess of 8-10 hours, a hopper dryer temperature of 120-150ºF is usually sufficient to achieve optimal moisture content.
