Neoprene is a popular material in making protective clothing for aquatic activities. Foamed neoprene is commonly used to make fly fishing waders, wetsuits, and drysuits as it provides excellent insulation against cold. The foam is quite buoyant, and divers compensate for this by wearing weights. [24]
A spraydeck is made of water-tight cloth or neoprene. It is sized to fit over the opening, or cockpit, of the canoe or kayak, with holes for the waists of the passengers. The spraydeck generally seals around the rim of the cockpit and around the torso of each passenger. Each opening in a spraydeck must make a fairly watertight seal.
The neck seal, the zip, the inflator, a wrist seal, and the manual cuff vent of a neoprene dry suit. Neoprene is a type of synthetic rubber which can be foamed during manufacture to a high proportion of tiny enclosed gas bubbles, forming a buoyant and thermally-insulating material, called "foamed neoprene", "foam-neoprene" or "expanded neoprene ...
A small strip of neoprene reversed with the rubber against the skin could help provide a sealing surface to keep water out around the neck, wrists, and ankles. In 1960, the British Dunlop Sports Company brought out its yellow Aquafort neoprene wetsuit, whose high visibility was intended to improve diver safety. [ 32 ]
Waders denotes a waterproof boot or overalls extending from the foot to the thigh, the chest or even the neck. They are traditionally made from vulcanised rubber , but available in more modern PVC , neoprene and Gore-Tex variants.
A single compression seal fitting may seal on a single or multiple elements. Sealing glands designed to seal on single elements consist of a body, cap, sealant and follower. When sealing on multiple elements, gland designs also include a seat and an anti-rotation pin to prevent wires or conductors from twisting and shearing.
Tear of latex neck seal. [47] Maintenance and pre-use inspection of dry suit zip and seals. [47] Use of a dry suit undergarment that retains moderate insulation properties when flooded (e.g. Thinsulate B). [65] [66] Use of a drysuit material having significant inherent insulation properties (e.g. foam neoprene). [47]
Cryogenic seals provide a mechanical containment mechanism for materials held at cryogenic temperatures, such as cryogenic fluids. Various techniques, including soldering and welding are available for creating seals; however, specialized materials and processes are necessary to hermetically entrap cryogenic constituents under vacuum-tight conditions.
