Engineered with Advanced Laminated PTFE

The performance of DEKOMTE’s PTFE bellows is underpinned by the use of multi-laminated PTFE tubes. These are produced using a precise lamination process that results in minimal porosity and a consistent wall thickness. This uniformity is essential for ensuring pressure stability, vacuum resistance, and chemical integrity.

Once the tubes are formed, they undergo a secondary transformation using controlled heat and pressure to shape them into high-performance bellows. This process enhances their structural strength and ensures long-term reliability, even in aggressive or variable operating environments.

Why Choose PTFE Bellows?

PTFE bellows are especially suited to applications where chemical resistance, temperature tolerance, and mechanical flexibility are critical. PTFE (Polytetrafluoroethylene) is known for its non-reactive nature and ability to withstand corrosive substances, making these bellows ideal for:

• Chemical processing plants

• Pharmaceutical production

• Food and beverage systems

• Semiconductor facilities

• Petrochemical installations

In these industries, avoiding leaks and contamination is crucial. PTFE’s resistance to almost all chemicals—combined with its non-stick and thermally stable properties—makes it the material of choice for protecting valuable infrastructure and sensitive processes.

Vacuum and Pressure Resistance

A major strength of DEKOMTE’s PTFE bellows is their ability to function under both vacuum and pressure conditions. Whether installed in systems that fluctuate between positive and negative pressure, or in setups that must retain absolute containment, these bellows perform consistently.

Their robust multi-layered design ensures they can handle extreme cycles and prolonged use without deformation or performance loss. This makes them especially valuable in installations where access is limited and maintenance shutdowns are costly.

Customisation Options

DEKOMTE can provide standard PTFE bellows or fully customised solutions tailored to your system’s needs. Whether you require specific movement capabilities, unique chemical resistance, or integration with flanges or liners, DEKOMTE’s engineering team can deliver a solution that fits precisely.

Each bellow can be supplied as part of a full assembly, ready for installation. All products are designed to meet both functional and regulatory requirements for your specific industry.
