Saint-Gobain Seals at ACHEMA’15: To Feature PI- & PTFE-based Sealing and Polymer Solutions

Published on 2015-05-15. Author : SpecialChem

GARDEN GROVE, California -- From June 15th to 19th, in Hall 9.0 - Booth #B62, at the ACHEMA Show 2015 in Frankfurt am Main Germany, Saint-Gobain Seals and Saint-Gobain Foams & Tapes will be showcasing their innovative solutions and materials for industrial applications. The ACHEMA show is one of the world’s leading trade fairs that offers a comprehensive overview of new trends and requirements in the chemical and biological industry. Both Saint-Gobain business units are celebrating the 350th anniversary of their parent company based in France.

Saint-Gobain Seals will be featuring several sealing and polymer solutions:

  • Marathon® diaphragms
  • OmniSeal® spring-energized seals
  • Rulon® fluoropolymer compounds
  • Meldin® 7000 thermoset polyimide materials
  • Meldin® HT thermoplastic materials

The Marathon® diaphragm product is manufactured using premium PTFE or modified PTFE material under Class 10000 cleanroom conditions and Good Manufacturing Practice (GMP) process. The product has received several certifications such as USP Class VI, European Regulation 1935/2004 and 10/2011 and 3-A Sanitary Standard 20-25. Saint-Gobain Seals has over 45 years of experience in the design and fabrication of specialty diaphragms and PTFE components for pumps, becoming among the leaders and a trusted supplier to the world’s most respected OEM diaphragm valve and Air Operated Diaphragm (AOD) pump manufacturers.

Saint-Gobain Seals’ OmniSeal® product is a high-performance spring-energized polymer seal capable of handling extreme service conditions. Typically used where ultra-low friction, chemical compatibility and extreme temperature are required, the seals were originally developed to meet critical conditions encountered in turbine engines, rockets and missiles in the aerospace industry, and later developed to serve the most challenging oil and gas applications. Currently, OmniSeal® spring-energized seal products are accepted for use in a wide range of applications.

The Rulon® material is a family of proprietary, homogeneous materials mostly of PTFE based resins, engineered and developed with specific custom applications in mind. It includes a variety of high-performance bearings and components, which meet today's need for enhanced wear performance in a PTFE-based material. Primarily used in mechanical, electrical and chemical applications, the Rulon® material withstands a variety of harsh environments such as extreme dryness, cryogenic temperatures, water, steam and hydrocarbon fuel.

The Meldin® 7000 and Meldin® HT product lines consist of the most complete range of thermoset polyimide and engineered thermoplastic materials available on the market today. These materials are available in compression or injection molded and machined components as well as basic shapes for customization and design flexibility. Some recent application examples include: Meldin® 7000 OmniGasketTM seals for aircraft deicing systems, Meldin® HT seal rings for automotive transmissions and Meldin® 7000 bearings for launch vehicles such as Falcon 9, Altas V and Delta IV.

The Meldin® 7000 product to be featured at the ACHEMA show is widely used in many different applications in the aerospace or automotive market but also as a component in industrial machinery such as hot runner nozzles in injection molding machines. When a polymer is being processed by injection molding and has a high melting point (over 250°C), not many materials on the market can be used in this type of application. Without melting, keeping rigidity at high temperatures and being wear resistance (even with abrasive polymers), Meldin® 7001 material is a very strong choice for the application as it provides excellent thermal insulation between the melted polymer and the metallic hot runner, preventing the melted material from sticking and facilitating color change.

Saint-Gobain Foams & Tapes have provided practical, cost-effective solutions for more than 50 years for bonding, sealing, acoustical and vibration damping as well as thermal management applications. Their high-performance foam tapes are easy to handle, require virtually no clean-up, and can be evenly and consistently hand-applied or adapted to automated application. Experienced in the Habitat, Automotive, Industrial, Electronics and Energy markets, their team approach to providing solutions for critical applications has resulted in gaining customer confidence. They will be featuring the following barrier solutions at the show:
  • Chemfilm® PTFE films
  • CHR® adhesive tapes
  • FluoroWrap® electrical insulation films

Chemfilm® PTFE films are manufactured in state-of-the-art molding and skiving facilities that allow for the highest quality, tightest tolerances and cleanliness - a requirement for the most demanding applications. Saint-Gobain Chemfilm® products offer excellent electrical, thermal, physical and chemical properties over wide temperature ranges. Typical applications include pump diaphragms, tank lining, wireless communications, semiconductors, batteries, capacitors, displays and circuit boards.

CHR® pressure-sensitive adhesive tapes are used in virtually every industry. Adhesive tapes are constructed of various materials such as polyimide, silicone, aluminum, copper, FEP, PTFE film, Fiberglass, paper, UHMW, and other specialty materials coated with adhesive, providing superior non-stick surfaces and allowing equipment to work smoothly and more efficiently. These high performance tapes are designed for applications that require chemical and heat resistance – “Protective Tapes for Extreme Conditions™.” Typical applications include winding, layer and lead insulation, coil covers, bundling, wrapping, banding, isolation and EMI-RFI Shielding.

FluoroWrap® electrical insulation films are characterized by high dielectric strength and chemical resistance, low moisture absorption and resistance to permeability -- ideal for electrical insulation. Beside Polyimide films or multi-layer high performance films, Saint-Gobain offers paste extruded PTFE films, manufactured to industry specifications for electrical insulation, aerospace, battery and fuel cell applications. Typical electrical applications are coil winding, wrapping wire harnesses, wire bundles, cable insulation, submersible pump motors, power cables and splicing tapes.
