[Velcro USA Inc.] A registered trademark for a reclosable fastener system patented in 1948 by George de Mestra, a Swiss inventor (patent expired in 1978). Velcro is a two-component nylon system in which one component has hooks and the other has loops. When pressed together, the Velcro hooks firmly grasp the loops. The two components may be separated by pulling. Velcro produces two types of hook systems: flexible and molded. The flexible woven hooks provide maximum cycle life while the molded hooks provide maximum fastening strength with limited cyclability. Velcro fasteners work effectively in temperatures ranging from -56C (-70F) to 93C (200F). The fasteners may be attached to substrates by sewing, heat sealing or pressure sensitive adhesives. Factory applied pressure-sensitive adhesives can be acrylic, cement rubber, or Polyurethane based materials.


Hazards and Safety

Nylon becomes brittle when exposed to extremely cold temperatures or ultraviolet light.
