Parker's synthetic webbing was super-strong but it only lasted a few hours.
Peter's web fluid was/is a shear-thinning liquid (virtually solid until a shearing force is applied to it, rendering it fluid); the exact formula is as yet unknown, but is related to nylon. On contact with air, the long-chain polymer knits and forms an extremely tough, flexible fiber with extraordinary adhesive properties. The web fluid’s adhesive quality diminishes rapidly with exposure to air. (Where it does not make contact with air, such as the attachment disk of the web-shooter, it remains very adhesive.) After about 2 hours, certain imbibed ethers cause the solid form of the web fluid to dissolve into a powder. Because the fluid almost instantly sublimates from solid to liquid when under shear pressure, and is not adhesive in its anaerobic liquid/solid phase transition point, there is no clogging of the web-shooter’s parts. </geekboy mode>
