PTFE TUBES

PTFE extruded tubing is manufactured by high pressure PTFE dispense resin mixed with additive, it is extruded and sintered. According to different demands, the tubing could be opaque or translucent.

PTFE TUBE is suitable for contact with food, according to the FDA CFR 21.177.1550

  • KEY PROPERTIES

• High and Low Temperature Resistance: continuous operating temperature 70℃~+260℃.
• Corrosion Resistance: chemically stable except fluorine gas, alkali metals dissolved.
• Weatherability: the best anti-aging plastic; Outdoor long-term use will not degrade.
• High Lubrication: the lowest coefficient of friction of any polymer.
• Non-adhesive: prevent the adhesion of almost all pollutants, water contact angle θ=110º.
• Non-toxic: doesn’t cause allergic reactions, compatible with human tissue and body fluids.
• Flame resistance: non-combustible in air (oxygen index> 95%).
• Electrical properties: excellent electrical insulation, broadband dielectric constant and loss factor minimum.

  • FLANGE INSULATIONS KITS TGCD

    FLANGE INSULATIONS KITS • Flange insulation kits CPI-TGCD are typically used on offshore installations, seawater environments, chemical installations, oil refinery pipelines. • Flange insulation kits CPI-TGCD follow standards ANSI 16.5 & API 605, other standards need to provide more specifications according to our requirements. • Flange Insulation Kits CPI-TGCD consist of an insulating gasket; some insulating sleeves […]

  • RTJ GASKETS – TG30-TG31

    RTJ joints are indicated in applications high pressures and temperatures. They are designed to be accommodated in specific slots and flanges contact surfaces of the gasket and the flange must be carefully machined and finished. They are particularly suitable for very high pressures, up to 1000 psi. The RTJ gasket material should be a little softer than the flange itself […]

  • O-RINGS

    O-RINGS The use of O-rings extends to many fields. The main function that characterizes this type of joint is its ability to maintain the seal, preventing the mixture of liquids and gases. They are characterized by their versatility and resistance to high pressures and temperatures. The type of elastomer used in its manufacture can vary. We can offer […]

  • CPI-PTFE ST

    CPI-PTFE ST stainless steel lined  gaskets consist of a perforated stainless steel insert uniformly enclosed by PTFE. The synergy between the highly corrosion resistant PTFE mantle and the perfectly centred rigid stainless steel insert give the gasket exceptional chemical and mechanical properties preventing cold-fl ow in a wide pressure-temperature range. In extreme applications they are […]
