PTFE tape used for different sized fittings PTFE tape for natural gas. There are two US standards for determining the quality of any thread seal tape. MIL-T-27730A (an obsolete military specification still commonly used in industry in the US) requires a minimum thickness of 3.5 mils and a minimum PTFE purity of 99%. [3]
Invisible double-sided tape used to attach hair pieces or to hold delicate fabrics against the skin. Reflective tape High-visibility adhesive tape with retroreflective sheeting. Thread seal tape Polytetrafluoroethylene (PTFE) film tape commonly used in plumbing for sealing pipe threads. Ultra-high-molecular-weight polyethylene tape
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is chemically inert. [3] The commonly known brand name of PTFE-based composition is Teflon by Chemours, [4] a spin-off from DuPont, which originally invented the compound in 1938. [4]
Polytetrafluoroethylene (PTFE), better known by its trade name Teflon, has many desirable properties which make it an attractive material for numerous industries. It has good chemical resistance, a low dielectric constant, low dielectric loss, and a low coefficient of friction, making it ideal for reactor linings, circuit boards, and kitchen utensils, to name a few applications.
The Los Angeles abrasion test (LA abrasion) is the North American standard for testing toughness (resistance to abrasion and degradation [1]) of construction aggregate or gravel and its suitability for road construction.

Dennison Mending Tape from the second half of the 20th century. From the Museo del Objeto del Objeto collection. Pressure-sensitive tape, PSA tape, self-stick tape or sticky tape consists of a pressure sensitive adhesive coated onto a backing material such as paper, plastic film, cloth, or metal foil. It is sticky (tacky) without any heat or ...
The modern non-stick pans were made using a coating of Teflon (polytetrafluoroethylene or PTFE). PTFE was invented serendipitously by Roy Plunkett in 1938, [3] [4] while working for a joint venture of the DuPont company. The substance was found to have several unique properties, including very good corrosion-resistance and the lowest ...
