CONTINUOUSLY DIPPED:TRUMARK'SHIGH ELASTICITY powerbandshave the power edge! Created by the "continuous dipping method", Trumark's surgical tubing is gradually brought up to the desired wall thickness by passing a mandrel continuously through natural latex material. Any striations in the tubing run parallel to it's length. The tubing stretches smoothly in the same direction as the striations. This dipping process creates superior latex-rubber-tubing which generates maximum power plus greater resistance to tearing. It's "elasticity memory" is maintained even after repeated stretching.
EXTRUDED:Slingshotsmade offshore usually have powerbands that are ringformed, and are manufactured by extrudingthe tubing through an elongated die. Much like the process of making sausage, the latex material oozes out of a nozzle. This extruding process produces striations or "rings" in the latex material that lie in a plane perpendicularto the longitudinal axis of the tubing. Extruded tubing has a kind of gummy feel to it, and "freezes up" quickly as you draw it back to it's maximum stretching point.
