    • Versiv PTFE diagraphm: Ultraflex

    Used in the most demanding high-pressure applications, Versiv Ultraflex is an unmatched PTFE solution for the highest flex life requirements and permeation resistance.
    Ultraflex is a Versiv Multimaterial Composite made from premium high molecular weight fluoropolymer resins, via specialised surface treatments and our proprietary process. It has all the benefits of regular PTFE composites, plus enhanced flex resistance, especially for high-pressure requirements.

    Main benefits of Versiv Ultraflex for pump diaphragms:

    High chemical resistance:

    ‍PTFE composites highly resistant to chemicals, acids, and solvents. This makes them ideal for use in pumps that handle aggressive chemicals or corrosive materials.
    It is also resistant to hydrolysis, making it suitable for use in humid environments.

    High-temperature resistance:

    Versiv Ultraflex is non-flammable/ fire resistan and has excellent high-temperature resistance. It is thermally stable from -200°C to 260°C (-328°F to 500°F) without degradation, making it suitable for use in pumps that handle hot fluids.

    Flexibility and Durability:

    Versiv Ultraflex is thermally weldable and has superior flexibility, allowing for diaphragms that are thin and durable. It is also resistant to tearing and abrasion, which helps prolong their lifespan.

    Reduced permeation:

    Reducing permeation is about equipment reliability.
    Versiv Ultraflex allows for both the protection of equipment and environment, and the reduction of leakage and media loss.

    Smoother flow:

    PTFE materials have a very low coefficient of friction, which means they do not stick to other materials easily.
    This leads to time, materials and energy savings through the low friction & easy release properties. It also makes them ideal for use in pumps that handle viscous or sticky fluids.

    • PTFE sheets: Stop uPVC window sticking

    Thermally efficient and virtually maintenance free, uPVC windows and doors have become an increasingly popular and cost effective solution for commercial and residential buildings around the world.

    Manufacturing in high volumes requires streamlined operation for every part of the production process, and consistent release is a must to maximize output and minimise potential defects when welding uPVC windows and doors.

    Versiv PTFE release sheets cover the four heated welding platens on each corner of the window or door.

    With a superior release surface and temperature resistance of up to 260°C / 500°F, Versiv PTFE products are optimal surfacing materials used to prevent melted PVC from sticking to and building up on welding platens of your machinery.

    Offered as release sheets for V, flat and combined welding platens, Versiv release sheets are suitable to use in all hot plate welding processes, including RF and microwave systems. Easy-to-clean, the non-stick surface reduces the risk of contamination and weld failures, while offering excellent welding plate protection and reducing maintenance needs to a minimum.

    During the welding of uPVC windows and doors, Versiv PTFE release sheets cover the four heated welding platens on each corner of the window or door. This provides consistent release and prevents melted PVC from sticking to and building up on the welding platens of the machinery.

    Pump problems solved with Versiv Ultraflex:

    • Premature failure due to PTFE rupture has been solved by the exceptional flex-life performance.
    • Diaphragm delamination caused by bad etching, unsteady bonding quality to rubber and media permeation that destroys bonding/rubber has been overcome by higher quality sodium ammonia etching on a Flex Barrier constructed from a low permeation rate laminate with a barrier enhancement process. The result is excellent bonding with a significantly reduced stretch void index and a 30% reduction in permeation.
    • Contamination attributable to a diaphragm’s rough surface hasbeen eliminated by the smooth inert surface of the barrier.
    • For deep drawing manufacturing issues, where the problem’s root cause is stiff and heterogeneous material, the high quality and flexibility of these barrier films removes cause for concern.
