Polyethylene terephthalate / PET
- the most slippery and durable plastic that can withstand high loads in comparison with all other engineering and standard polymers.
Due to its high hardness, stiffness, strength, good toughness and high fatigue limit PET is widely used to replace metals in those places where it is impossible to use lubrication in a "dry friction", and to facilitate the construction and reduce the cost. PET sheetings and rods stand up to +110°C and shortly up to +170°C.
In tribological systems with moderate temperatures PET sheetings and rods replace with success Polyamides, Polyacetal with a significant increase in service life.
PET is resistant to cracking, has a very low, nearly zero, water absorption and excellent electrical insulating properties. Therefore it is used for production of precision parts, components employed in cold water, as well as for the manufacture of insulating components for electrical engineering and electronics.
PET sheetings and rods have good chemical resistance to petrol, oils, greases, alcohols, ethers, weak acids and bases, but not resistant to solvents, ketones, strong acids and alkalis.
Polyethylene Terephthalate / PET sheets
Polyethylene Terephthalate / PET sheets In its molecular structure, Polyethylene Terephthalate (PET) sheets are available either as an amorphous or semi-crystalline thermoplastic. Whereas the amorphous type is highly transparent and has a lower mechanical strength, as well as substantially inferior sliding characteristics than the semi-crystalline type, semi-crystalline types have higher hardness, rigidity, and strength with outstanding sliding behavior and low sliding wea..

What are the mechanical properties of Polyethylene Terephthalate (PET)?
The mechanical properties of Polyethylene Terephthalate (PET) include high hardness, stiffness, and strength. These characteristics allow PET to withstand high loads and perform well under conditions of dry friction. Additionally, PET exhibits good toughness and a high fatigue limit, making it suitable for applications that require enhanced durability.
In what applications is PET commonly used?
PET is widely used in various applications where it can replace metals, particularly in environments that do not allow for lubrication. Its ability to operate under high loads and in conditions of dry friction makes it ideal for components such as gears, bearings, and wear strips. For specific applications, consider our Polyethylene Terephthalate / PET sheets.
How does PET compare to other engineering plastics?
PET stands out among engineering plastics due to its superior abrasion resistance and low friction properties. Compared to other materials, it offers a unique combination of durability and versatility, making it a preferred choice in many engineering applications. Its performance in harsh environments often exceeds that of standard polymers, providing a reliable alternative for reducing weight and costs in engineering designs.
