Silnylon

Silnylon

Silnylon, a contraction of Silicone impregnated nylon, is a synthetic fabric used mainly in lightweight outdoor gear. It is made by impregnating (also called coating) a thin woven nylon fabric with liquid silicone from both sides. [cite web |url=http://www.specialtyoutdoors.com/tips/silnylon.asp |title=Tips for Sewing Silnylon |accessdate=2007-06-11 |work=Specialty Outdoors ] This makes it strong for its weight as the silicone adds to the fabric's tear strength, it is highly waterproof, but not breathable.

It is used in the manufacture of backpacks, tarps, ditty bags, etc, particularly by Ultralight backpackers.

Silnylon comes in several main types. The common type is a quiet, silky, very slippery fabric. The variant known as "crisp silnylon" is lighter, but brittle, noisy, and tears easily. Someversions are made from the stronger type 66 nylon and are used for parachutes, hot air balloons etc.Some use a blend of silicone and urethane which is done partly to reduce the air pollutionduring manufacture as it reduces the aromatic solvents used in the coating process.
