PTFE TEFLON ROLLS AND FILMS

Teflon PTFE rolls and films are versatile and highly functional products valued across many industrial sectors. Made from polytetrafluoroethylene, a synthetic polymer renowned for its exceptional physical, mechanical, electrical, anti-adhesive, and chemical resistance properties, they also offer unmatched performance in terms of thermal stability and a low friction coefficient.

 

Physical and chemical properties

Chemical resistance: PTFE is virtually inert to almost all chemical agents, including acids, bases, solvents, and oxidizers. This makes it ideal for applications in highly corrosive environments.

Thermal stability: PTFE can withstand extreme temperatures, from -70°C to +260°C continuously and up to +315°C for short periods. This property makes it suitable for high-temperature applications.

Hydrophobicity: Teflon is one of the most hydrophobic materials known, with excellent resistance to the adhesion of aqueous and oily substances.

Low coefficient of friction: extremely low coefficient of friction makes it ideal for sliding and non-stick applications.

Teflon PTFE rolls

Teflon PTFE rolls are a convenient and versatile form of this polymer material. Available in various sizes and thicknesses, they offer multiple benefits and applications.

 

Features and benefits

  • Flexibility: Teflon rolls can be cut or shaped easily to fit different applications.
  • Chemical and Thermal Resistance: they have the exceptional properties of Teflon, making them suitable for aggressive environments and high temperatures.
  • Non-stick: the surface of the rolls is smooth and non-adhesive, preventing substances from sticking and facilitating sliding.
  • Easy Cleaning: their hydrophobic and non-porous surface allow the rolls to be easy to clean and resistant to contamination.
  • Resistance to Aging: PTFE does not degrade and maintains its properties even after exposure to environmental factors such as heat, ultraviolet light, and oxygen. This resistance to ageing ensures durability for products made with this material.

 

Teflon PTFE adhesive films

Chemical and thermal resistance: inheriting the properties of Teflon, these films are resistant to chemical agents and high temperatures.

Low coefficient of friction: the surface of the adhesive films is smooth, facilitating sliding and reducing friction.

Non-adhesive: with a non-adhesive surface, these films prevent the adhesion of substances.

Abrasion resistance: these films offer good resistance to abrasion and wear, ensuring durability.

Processes of Teflon PTFE rolls and films

 

Cutting and shaping

Teflon PTFE rolls can be easily cut and shaped using conventional cutting tools, including scissors, blades, or cutters. This manufacturing flexibility allows the creation of custom gaskets, seals, and coatings for various applications.

 

Thermoforming

Teflon PTFE can be thermoformed to create conformal components and coatings. This technique involves heating the material to a specific temperature and forming it using moulds or matrices.

 

Injection moulding

Teflon PTFE can be processed by injection moulding to produce small components or those with complex geometries. This process involves melting and injecting the material into a mould to achieve the desired shape.

 

Application of adhesive films

Adhesive films can be applied to smooth or slightly curved surfaces using lamination techniques or manual application. This method allows the creation of protective or non-stick coatings on industrial components and equipment.

 

Welding and gluing

Although Teflon PTFE is challenging to weld or glue due to its chemical inertness, other techniques are available to join or repair components from this material, which require specific equipment and expertise.
