PermatronŽ is an industrial polypropylene fabric made by Baycor Corporation and is specifically engineered for rebounders, trampolines and pool covers. Polypropylene is resistant to ultraviolet rays, doesn't break down as do other fabrics commonly used in imported rebounders such as canvas, nylon or plastic, and allows no moisture absorption. Polypropylene is suitable for indoor as well as outdoor use and resists weather conditions such as precipitation and sunlight. Each fiber is placed under nearly 200 tons of pressure in a 1600 degree oil drum bath resulting in a smooth textured surface.
Polypropylene is flexible, but does not stretch. It provides a firm and stable jumping surface while remaining supple enough to cushion joints and provide a minimal impact exercise. It does not permanently crease or fold and always retains its original flat surface.

There are several companies in North America who produce polypropylene fabric for trampoline or rebounder use. They all utilize quality polypropylene threads in their weaves. The same cannot be said for Asian manufacturers making knock-off fabrics (some illegally using registered trade names). For the safest and most effective jumping surface, insist on North American polypropylene!
