PTFE Teflon Sheets: Major Benefits and Applications

Teflon is one of the most significant engineering plastics invented long back around seven decades ago, it is still a crucial material that offers better performance in vital areas compared to most other engineering plastics. When it comes to PTFE Teflon Sheets, there are special attributes that are highly compatible with a range of industrial applications.
Wide Range of Applications:
The striking properties of these sheets make them suitable for a wide spectrum of applications. PTFE Sheet is frequently used in industries involving food preparation because it does not contaminate or cause any harm to the food when in contact.
Because it is compatible with high temperatures, it is a well suited material for cryogenics. This engineering plastic is widely used in the construction industry and is increasingly recognized by modern architects because of its considerable ability to resist weathering and environmental variations.
A material widely acclaimed for its low frictional co-efficient, PTFE sheet which is widely used in slide ways and wear strips associated with various types of engineering procedures. It helps in cost reduction by enhancing the life span of high performance constituents offering a super sliding and wear and tear resistant framework.
Teflon sheets also offer a durable valve seal due to its acid and heat resistance properties. Due to its crucial properties, the sheets find use in areas where other materials are not sufficient or compatible.
Characteristics and Specific Benefits:
• Low friction: One of the major characteristics of theses sheets is the amazingly low frictional co-efficient, which in fact is the lowest amongst any material that man has discovered yet, and offers the same results as ice. This property is exceptionally useful in numerous applications like slide ways requiring low friction where only Teflon Sheets can be suitably used.
• High temperature resistance: One of the most popular uses of Teflon is in sectors requiring a high range of temperature. This is due to the fact that this material can withstand wide variations in temperature. It works well in temperatures as high as or even more than 250°C and is also able to withstand extremely low temperatures, while retaining the same performance level. In fact, since this engineering plastic can resist temperature ranges as low as -260°C without any effect on the properties, it often finds adequate use in lining the interior part of cryogenic vessels. Few materials can effectively resist temperature extremes like this.
• Chemical resistance: One of the most important benefits of this plastic is derived from its striking chemical resistance which when compared to other plastics in indeed very high. Hence there are hardly any chemicals that can cause damage to the sheet during common applications and uses. The acid resistance property of PTFE sheets is especially a very significant feature, which make it a choicest material for lining acid tanks. Interestingly, these sheets can withstand higher acid concentrations than most other materials.
• Electrical Insulation: Amongst all the currently in use engineering plastics, PTFE is popularly regarded as one of the best materials for electrical insulation. Frequently PTFE Sheets are used as a good alternative for PVC if the insulation properties are required to be of a much higher level.
