PTFE slide bearing sheets

PTFE has the lowest friction coefficient of all plastics even if these are lubricated. Typical behaviour is whenever the load on PTFE increases friction coefficient becomes lower. PTFE has no "stick slip" behaviour which is unique in slide bearing technology.

Characteristics as stated above means an advantage for PTFE in bearing applications. Due to the fact no lubricants are required, PTFE (or compounds) is often used in food industry, road (bridge) construction, support of pipe systems and heavy installation constructions. By adding PTFE to the free movable construction parts (metal, rubber and so on) shrink and expansion, due to temperature movements, will not become an issue.

PTFE 100% virgin is a relatively soft material and can be too porous for heavy constructions. By adding fillers to the PTFE, required characteristics for specific applications will improve.
For example glass, bronze, graphite or carbon are commonly used. Friction coefficient will be slightly influenced due to these fillers. In general most optimal gliding construction with lowest friction is obtained in case PTFE is maximal loaded and counter surface is highly polished.

Expanded PTFE Sheet

Expanded PTFE Sheet is a high performance sheet gasket material made of multi-directionally expanded virgin PTFE. It is a soft, form-in-place gasket material that conforms to almost any sealing surface. It is capable of withstanding a wide range of pressure, temperature and chemical environments. Due to its highly fibrillated microstructure, it has excellent creep resistance compared with other PTFE products.

Expanded PTFE sheet is an extremely compressible material manufactured from 100% virgin PTFE. It is a food approved product and has excellent resistance to a wide range of chemicals, making it a popular sealing material in the food, drink and pharmaceutical industries.

Temperature: -240°C to +270°C (briefly up to +315°C)

Key Features: Very soft, extremely compressible and has excellent resistance to many chemicals. It can withstand compressive loads of over 40,000 psi without losing sealing capability. It is also unaffected by ozone, UV and corona and does not become brittle with age.

100% pure expanded PTFE sheet has a microporous fibrous structure unique mechanical properties. Widely used for sealing flange joints in pipelines as well as hydraulic and pneumatic systems. Pure, multidirectionally expanded PTFE, asbestos free, chemically resistant to fluids from 0 to 14 in the pH range.

Polycarbonate Sheets Vs. Plastic

Polycarbonate sheets have been proven to be superior to other plastic materials used in similar applications in almost every area of comparison. Furthermore, with various categories in polycarbonate available, it is polycarbonate multiwall sheets that are the finest ones as they perform the most effectively for long years with low maintenance and provide excellent value for money. Made from extruded sheets, there are no thickness variations seen in these sheets, unlike other plastics. Let us compare polycarbonate and plastics in a few areas of functionality to see which one proves better.

Polycarbonate provides up to 89% light transmission while plastic provides 80%.
Polycarbonate provides excellent impact and weather resistance, compared to the average resistance in case of plastics.
Temperature resistance in case of polycarbonates ranges up to 120 degree Celsius, while in case of plastics is only below 100 degree Celsius.
Polycarbonate is self-extinguishing and plastic is flammable.

With all these properties, you can get a clear understanding of why polycarbonate is far better than plastic. Last but not the least, polycarbonate is far more easier to maintain than plastic.

Convinced enough to opt for polycarbonate? For any kind of polycarbonate sheet, you can rely on the products provided by Tuflite Polymers.

Types of polycarbonate sheets

Solid and textured polycarbonate sheets
Solid and textured sheets can withstand weather extremities, may it be heavy rains, scorching winters or zero degree winters. They have high impact strength, durability, flexibility, and are transparent and light weight. They also possess thermal and chemical resistance. They are also easy to cut and drill. Moreover, they are very easy to store, handle and install. Besides, they are also available in embossed texture that gives the appearance of frosted glass, thus enhancing the look for indoor and outdoor applications.

Multiwall polycarbonate sheets
Multiwall sheets are those versatile sheets that provide outstanding flexibility, heat reflection and light transmission. They are manufactured from high quality polycarbonate resin that provides high impact strength, transparency and light-weightiness to the sheets. These sheets can also tolerate extreme weather conditions, and are also flame resistant.

Corrugated polycarbonate sheets
Corrugated sheets have superior performance with excellent impact resistivity. They are fit for commercial, industrial and residential applications as they are manufactured with precise specifications and are greatly beneficial for enhancing daylight harvesting. These sheets adopt two-wall structures that provide high light transmission and superior strength.
