Featured Product – Durlon® 9645


Durlon 9645

Durlon® 9645 – Microcellular PTFE with Rigid PTFE core

The Durlon® 9645 product range offers a biaxially-oriented PTFE sheet solution that combines superior chemical resistance with exceptional sealing performance, making it an optimal choice for demanding industrial applications.

Engineered to perform across a broad temperature range from cryogenic conditions up to +260°C, Durlon® 9645 is suitable for handling aggressive media spanning the full pH spectrum (0 to 14). This advanced material is designed for applications requiring minimal creep and reliable seal integrity, particularly in scenarios where low leakage is critical, and conventional PTFE materials fail to meet the requirements.

Durlon® 9645 is designed with controlled microporosity and a closed-cell structure, delivering excellent compressibility and reliable sealability, even at low bolt torque. The compressible PTFE surface layers make Durlon® 9645 ideal for warped, pitted, or scratched flanges, as the microcellular layer conforms effectively to surface irregularities.

The rigid PTFE core minimizes cold flow and creep, significantly enhancing durability and long-term performance. It also improves handleability and simplifies installation, particularly on large-diameter flanges or in hard-to-reach locations. Durlon® 9645 is an excellent choice for low torque applications, such as glass-lined flanges and equipment, where traditional solutions often struggle to perform.

Moreover, Durlon® 9645 is compatible with a wide range of chemicals, including strong acids and aggressive caustics, ensuring versatility across various industries. This material is also a superior alternative to envelope gaskets, offering robust sealing performance with added durability and ease of use.

Certifications:

  • FDA: Conforms to the requirements of 21 CFR 177.1550 for food and drug contact
  • TA-Luft (VDI Guideline 2440): Approved Material

Featured Industry – Food-based Pharmaceuticals

The food-based pharmaceuticals industry is advancing rapidly as producers develop therapeutic and functional products that merge pharmaceutical precision with food science. This field requires tightly controlled processes that preserve the stability of active ingredients while meeting rigorous standards for purity and safety. Operations commonly involve blending, extraction, fermentation, thermal processing and aseptic handling, all of which demand hygienic equipment capable of maintaining integrity under variable temperatures, pressures and chemical exposures.

Material selection for sealing components is especially important due to the sector’s strict requirements for sanitation, cleanability and contamination prevention. Gaskets must resist organic compounds, oils, alcohols, steam, cleaning agents and frequent thermal cycling while sustaining reliable sealing performance. Maintaining system integrity is essential not only for regulatory compliance but also for reducing downtime, improving batch consistency and supporting efficient production.

FDA compliant Durlon® gasket materials provide performance advantages well aligned with these operational needs. Durlon® 8500 offers strong chemical resistance and durability for general process applications. Durlon® 9000 and 9200 deliver suitability for aggressive media and higher purity requirements, making them valuable in systems that handle sensitive formulations. Durlon® 9600 and 9645 provide reinforced stability, improved sealing recovery and dependable performance during repeated sanitation and sterilization cycles. For low temperature environments or chilled processing lines, Durlon® LT100 offers reliable sealing while maintaining compliance with food and pharmaceutical standards. Collectively, these materials support validation, enhance operational reliability and help protect product integrity.

Typical applications across food-based pharmaceutical facilities include pumps, reactors, mixers, heat exchangers, piping systems and packaging equipment. In each case, gasket performance directly influences hygiene control, process stability and regulatory adherence. Selecting Durlon® materials that correspond to specific process media, temperature ranges and cleaning protocols allows manufacturers to optimize system performance while minimizing maintenance frequency.

As the industry continues to evolve toward more complex formulations and higher production standards, high quality sealing solutions will remain vital. FDA compliant Durlon® materials offer dependable options that support safe, efficient and compliant operations within the expanding food-based pharmaceuticals sector.
