PTFE - Polytetrafluoroethylene (*)
PTFE is a material highly valued for its unique properties, making it ideal for numerous technical applications. Among its main advantages are its extremely low coefficient of friction, which ensures smooth sliding and reduced wear, its excellent resistance to chemicals and external agents, its outstanding non-stick characteristics, and its remarkable ability to withstand extreme temperatures, ranging from -200°C to +260°C. In addition, PTFE offers excellent electrical insulation properties.
PEEK - Polyetheretherketone (*)
PEEK (Polyetheretherketone) is a high-performance engineering polymer, highly appreciated for its excellent mechanical, thermal, and chemical resistance. It can operate continuously at temperatures up to 250°C while maintaining dimensional stability and structural integrity. It is resistant to hydrolysis, aggressive fluids, wear, and radiation. PEEK is ideal for applications in extreme environments such as aerospace, oil & gas, medical, and food industries. Its low coefficient of friction makes it particularly suitable for sliding and sealing components.
PE UHMW - High Density Polyethylene
UHMW PE (Ultra High Molecular Weight Polyethylene) is a thermoplastic material characterized by outstanding resistance to wear, abrasion, and impact. It offers an extremely low coefficient of friction, excellent non-stick properties, and exceptional sliding performance. Chemically inert, it resists many chemicals and moisture. UHMW PE is commonly used for guides, sliding pads, protective elements, and components subject to high friction, ensuring durability and performance even in the most demanding conditions.
POM-C - Polyoxymethylene Copolymer (*)
POM-C (Polyoxymethylene Copolymer) is a highly appreciated engineering polymer known for its excellent dimensional stability, stiffness, and mechanical strength. It offers very good sliding properties, a low coefficient of friction, and excellent machinability. POM-C is resistant to moisture, wear, and many chemical agents. It is widely used for the production of precision components such as gears, bushings, guides, and structural parts, ensuring excellent performance even in humid environments or in contact with food.
PET - Polyethylene Terephthalate (*)
PET (Polyethylene Terephthalate) is a semi-crystalline engineering polymer known for its excellent dimensional stability, high mechanical strength, and wear resistance. It offers good sliding properties and low moisture absorption, making it ideal for precision applications. PET is particularly resistant to chemicals, impact, and abrasion. It is commonly used for the production of technical components such as gears, rollers, guides, bushings, and parts subject to mechanical loads.
PA6 - Polyamide 6 (*)
PA6 (Polyamide 6) is a versatile engineering polymer, highly appreciated for its excellent mechanical strength, good toughness, and impact absorption capability. It offers very good sliding properties, wear resistance, and is easy to machine. PA6 is widely used for the production of structural components, gears, sliding pads, bushings, and guides. It shows good resistance to oils, greases, and fuels, although it is sensitive to moisture absorption, which may affect its dimensional stability in certain applications.
PA6 - Polyamide 6.6 (*)
PA6.6 (Polyamide 6.6) is an engineering polymer characterized by higher mechanical strength, stiffness, and thermal stability compared to PA6. It offers excellent sliding properties, high wear resistance, and reliable performance in higher temperature environments. PA6.6 is resistant to oils, greases, hydrocarbons, and many chemical agents. It is widely used for the production of gears, bushings, rollers, guides, and structural components subjected to static and dynamic loads in various industrial sectors.
PVDF - Polyvinylidene Fluoride
PVDF (Polyvinylidene Fluoride) is a fluorinated engineering polymer that combines excellent mechanical properties with outstanding chemical resistance. It withstands numerous aggressive agents, acids, solvents, and UV radiation. PVDF remains stable at temperatures up to 150°C and has very low moisture absorption. It is widely used in the production of components for the chemical, food, and pharmaceutical industries, as well as for systems in contact with corrosive fluids, ensuring long-lasting performance and operational safety
PVC - Polyvinyl Chloride
PVC (Polyvinyl Chloride) is a highly versatile and widely used thermoplastic material thanks to its good balance of mechanical properties and chemical resistance. It offers good rigidity, dimensional stability, and abrasion resistance. PVC is particularly suitable for applications in humid environments or in contact with moderate chemical agents. It is commonly used for the production of flanges, fittings, seals, pipes, and technical components for the chemical industry, hydraulics, and water treatment systems.
