Teflon Sheet

teflon sheet 1. Thickness: 2 - 80mm 2. Normal Size: 500mm x 500mm, 600mm x 600mm 600mm x 1200mm 1000mm x 1000mm 1000mm x 2000mm PTFE Sheet is officially in the record book as havingthe lowest co-efficient of friction of any solid materialand is extremely effectiveoperating at very high and very low temperatures. It has fantastic chemical resistanceand superb electrical insulation properties. PTFE Sheetcan be tricky tobond, but it is non melting and is self extinguishing Arguably one of the most important engineering plastics is a material called PTFE. Although PTFE was invented back in the 1940's, it still remains a critical component that continues to outperform almost all other engineering plastic in specific and critical areas. Benefits of PTFE Sheet PTFE Sheet is specially important because of its outstanding lack of friction and slippiness, this is so incredibly low that is has been described as being the most slippy solid material known to man and PTFE Sheet can be cut into strips and can offer a massive improvement in the sliding components. PTFE is also highly specified due to its very high temperature resistance allowing components to withstand almost double that of other types of engineering plastic. PTFE Sheet has the capability to also withstand very strong acids and chemicals helping to provide solutions to acid storage and chemical problems. High electrical resistance is yet another feature of PTFE Sheet and PTFE is often used in high end electrical resistance appliances. PTFE Sheet Applications PTFE Sheet is often used in the food preparation industry due to its food contact suitability and its very high operating temperatures meaning that the PTFE will be happy to continue along with the product and any product or contamination will not be allowed to stick. PTFE Sheet is also highly successful when it comes to cryogenics, just as PTFE is comfortable at very high temperatures, PTFE is also very happy at extremely low temperatures. PTFE Sheet is also becoming popular in the building industry and is being specified by modern architects due to its substantial ability to withstand weathering and its environmental resistance. PTFE Sheet is often used in wear strips and slideways within all types of engineering to take advantage of a stunning co-efficient of friction to guide high performance components a highly wear resistant and super sliding advantage to help reduce costs and improve component life. PTFE Sheet is also used in valve parts because it has the ability to conform to the shape of a mating or sealing, opposing component allowing PTFE to give a low friction long lasting valve seal that is heat and acid resistant. Because PTFE Sheet has excellent electrical insulation properties, it is often specified for the areas where other insulation is not sufficient and with the added benefit of the heat resistance which can often be associated with these applications. PTFE Sheet Specifications Maximum long term working temperature is 260°C. Maximum short term working temperature is 260°C. Co-efficient of friction is 0.08. Co-efficient of expansion is 12. Melting point is 327°C. PTFE Sheet availability PTFE Sheet is generally available in a standard sheet size of a nominal dimension of 1200 x 1200, although there is a limited option of 1500 x 1500 PTFE Sheet's are available in some selected sizes. PTFE Sheet is also often reduced in overall size availability of 600 x 600 due to weight and costs. Thickness of PTFE Sheet typically range from 0.25mm up to 100mm thick although specialist manufactures are capable of much greater thickness. PTFE Sheet offers a great and comprehensive range of thickness, although the thinnest sheet is very difficult to keep flat, smooth and wrinkle free. Points to remember regarding PTFE PTFE has a few important areas to be aware of and they are it's thermal expansion, this means that components will expand at a high rate due to thermal changes, PTFE Sheet is also difficult to bond, there are modern adhesives that will bond PTFE, they are often a two part process although pre-etched PTFE Sheet is available. PTFE Sheet is also relatively heavy or dense compared with other engineering plastics and also it can be more expensive due to its manufacturing process.
