PTFE is a fluoropolymer that exhibits astonishing chemical resistance and ultra high-purity. Self-lubricating and with a low friction coefficient, PTFE sheets and rods are ideally suited for the manufacture of high-temperature seals, insulators and bearings used in semiconductor, aerospace & chemical processing industries. PTFE's low coefficient of friction makes it suitable for applications where sliding action of parts is needed: such as plain bearings, gears, and slide plates. In these applications, it performs significantly better than nylon and acetal; and is comparable to UHMW. PTFE however can be used over a far wider temperature range than these materials; -100?F to +400?F (-73?C to 204?C) and offers superior electrical insulation properties. Although its' mechanical properties are low compared to other engineering plastics, those properties can be enhanced through the use of additives such as Carbon, Graphite, Bronze, and Glass Fiber. The most commonly known brand name of PTFE-based formulas is Teflon? by Chemours
ROPE-SAFETYPRO-1/2"X120-KERNMANTLE, Construction: Kernmantle, Core: Polyolefin, Cover: Polyester, Diameter: 1/2" (12mm), Features: Resists flattening & glazing; Excellent knot holding properties; Low elongation; Very little bounce, Length: 120', Milks: No, Package: Polybag, Spliceable: No, Tensile: 6600 lbs., Weight Per 100': 7.5 lbs., Notes: Safety Pro-12 is designed for applications where a fixed spliced eye is not necessary. Its unique, Notes: construction results in a rope that is easy to knot yet resists flattening and glazing., Notes 2: The twelve strands are braided around a bundle of our trademark ?blue? nylon core yarns. The result, Notes 2: is a rope that strikes the balance of firm and supple with minimal bounce so there is little wasted, Notes 2: energy climbing.
