CONTINUOUSLY DIPPED: TRUMARK'S HIGH ELASTICITY powerbands have 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: Slingshots made overseas usually have powerbands that are ring formed, and are manufactured by extruding the 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 that is perpendicular to the longitudinal axis of the tubing. Extruded tubing usually has a kind of gummy feel to it, and begins to "freeze up" quickly as you drawn it back to maximum stretching point.
