Description
Material Notes:
This two-component polyurethane casting system makes type of soft elastomer material known as “gel”. Applications for this material include filling component for computer keyboard/mouse-pad wrist rests, bicycle/motor cycle sheeting, surgical bed cushions, respirator gaskets, vibration dampening, and many other specialty applications. The component materials are liquid at room temperature. The mixture cures at room temperature. The material can be cast into molds to make parts, inserted into a film encapsulation, or open cast into a frame to make a sheet. The standard pot life is 15 minutes, so it is possible to hand-batch for prototyping, small run production, and a large batch.Information provided by Northstar Polymers.
