PTFE Expanded

At MEREFSA, we offer Expanded PTFE Profiles, a soft, malleable, and flexible material designed to ensure optimal sealing in various applications. Its adhesive side facilitates installation, especially on vertical surfaces, enhancing the ease and precision of assembly. Additionally, we supply this material in sheets and standardized seals, providing versatile, high-quality solutions for demanding industrial environments.

Product Information


Industrial applications. Its development through a specific treatment of Fluorocarbon with PTFE gives it high tensile strength, flexibility, low hardness, and excellent chemical and thermal resistance, making it an ideal solution for sealing joints and gaskets in extreme conditions.


It is available in sheets of 1.5 mm, 2 mm, and 3 mm thickness, allowing for the manufacture of die-cut flat gaskets, standardized gaskets, and a wide variety of expanded PTFE profiles, offering versatile options tailored to various industrial needs.

Advantages of using expanded PTFE


Save time: Expanded PTFE is easy to install thanks to its self-adhesive surface, adapting to surface irregularities without the need for complex adjustments. It is non-stick, so it doesn't require scraping during maintenance, and its high compressibility ensures an optimal seal.


Long-lasting: Made with 100% PTFE, it is highly resistant to compression, with no risk of tearing or deformation. It withstands pressures up to 210 Kg/cm² and temperatures ranging from -265 ºC to +315 ºC, being chemically inert, non-contaminating, and with no expiration date.


Cost savings: It minimizes waste by eliminating the need to manually cut gaskets. No maintenance is required, reducing operational costs, and its storage is efficient, as it doesn't take up much space or require large stocks.


Applications: Ideal for smoke and gas ducts, heat exchangers, glass installations in fine chemicals, tanks, pumps, steam systems, hydraulic, and pneumatic systems.


Expanded PTFE is a versatile, efficient, and durable solution, perfect for applications with high chemical and mechanical demands.

Assembly


The expanded PTFE profile is a soft, malleable, and flexible material, designed with an adhesive side to facilitate installation, especially on vertical surfaces.


Instructions

  • Surface cleaning: Ensure that impurities or residue are removed from the edge where the profile will be applied.
  • Remove the protective paper: Carefully peel off the adhesive backing.
  • Profile placement: Apply the profile at the center of the joint, ensuring it is properly aligned in the form of a flat gasket.
  • Overlap (except on glass): In the sealing seat area, overlap 1 to 2 cm in the same direction as the tightening.
  • Seal and adjustment: Tighten the seal; once compressed, the profile will be equivalent to 1.5 times its width.

*In glass installations, the profile should not be overlapped, as tightening may cause the glass to break.*
