An Introduction to Lubrication Management
(Language: English)

This white paper is designed to be a useful overview of lubrication management through the lens of sealing solutions. It draws on the expertise both within Trelleborg Sealing Solutions and in the wider industry to provide a ‘jumping-off point’ in tribology. A point at which you can deal in the world of sealing and lubrication with a greater knowledge and grounding – from its history and development to the latest solutions and approaches.

Testing of HFC Fluids on Common Seal Materials in High Temperature Applications

As the oil and gas industry moves to recover more challenging reserves and enters the development of High Pressure High Temperature (HPHT) fields, the risk of fire is increasing. There is therefore a move to the use of water-based hydraulic fluids, which present significant sealing challenges. This whitepaper takes an in-depth look at sealing materials and testing in HPHT environments.
Stick-Slip Solution - The importance of damper integration in dynamic sealing

In this whitepaper, we take a closer look at the problem of stick-slip and how dampers can combat or otherwise minimize it. It must be noted that, academically, there exists very little consensus as to the underlying principles of stick-slip – so, this paper will take a practical perspective, addressing how engineers can use dampers to reduce resultant noise and vibration; once again mastering the force of friction.
Supporting the Advancement of Drug-Eluting Devices

Drug device combination products (defined as medical devices integrated with drugs) can be produced in and by a variety of materials and processes. Silicone is one of the most successful materials used for combination products, particularly for implantable products and is the focus of this whitepaper.

Fighting Hospital Acquired Infection

  • Applying antibiotic Active Pharmaceutical Ingredient (API) coatings to silicone catheters by spraying or dipping
  • Addition of antibiotic APIs to raw silicone
  • Impregnation of vulcanized silicone with antibiotic API through immersion

This whitepaper outlines these three techniques and presents test results proving the effectiveness of the immersion impregnation method in combining an API with silicone tubing to prevent catheter-associated infections.

Composite Simulation Grows MORE ROBUST

By Kenneth Wong

THE TRANSITION FROM METAL to composite is one of the most recent significant changes in manufacturing.
The former material is isotropic, exhibiting uniform stretching and bending behavior in all directions. By contrast,composites are anisotropic. They stretch, bend and break differently in different directions, based on how the fibers are woven together and how the laminates are bonded. This fundamental difference throws many traditional simulation protocols and practices into chaos.
