Nylon Plastic | Strong, Stiff, Bearing & Wear Material

Nylon 6/6– sheet, rod, and tube are usually produced by melting solid pellets of the polymer and processing them through a thermoplastic extruder. Extrusion is a fast and economical method for making small diameter rod, tube, and thin sheet. Unlike cast Nylon 6 stock shapes, extruded Nylon 6/6 sheet, rod, and tubing can be manufactured to any length, which can be an advantage for cost

Teflon Vs PTFE What Really Are The Differences?

Teflon is a synthetic polymer containing carbon and fluorine called polytetrafluoroethylene. That’s right, Teflon is PTFE but by another name. Teflon is the trademarked brand name for PTFE owned by Chemours, and just as we call our vacuums Hoovers and sticky tape Sellotape, so we’ve come to know PTFE by the name it was given.

resistance, low and high temperature capability, resistance to weathering, low friction, electrical and thermal insulation, and "slipperiness". ( see also Teflon® PTFE and Teflon® FEP & PFA Specifiions ) PTFE''s mechanical properties are low compared to other plastics, but its properties remain at a useful level over a wide temperature range of of -100°F to +400°F (-73°C to 204°C

Polytetrafluoroethylene - Wikipedia

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous appliions. The commonly known brand name of PTFE-based compositions is Teflon by Chemours, a spin-off from DuPont, which originally discovered the compound in 1938.. Polytetrafluoroethylene is a fluorocarbon solid (at room temperature), as it is a high-molecular-weight polymer consisting

Chemical resistance of materials | Tameson

It is very robust and resistant to many chemicals, but for example less suitable for sea water or distilled water. Stainless steel is recommended for corrosive media, such as seawater. Moreover, it is wear-resistant, which makes it very suitable for intensive use. Nylon is the cheapest variant, has good mechanical properties and is suitable for many media.

The presence of fluorine provides even greater chemical resistance, especially to strong acids, and results in a low coefficient of friction, low moisture absorption, and high electrical resistance. PTFE mechanical properties are low compared to other polymers, but its flexibility at low temperatures is a key feature. PTFE is stable at temperatures up to 500˚F (260˚C) PTFE is commonly used
