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.
Flüssigsilikontechnologie (LSR) für smarte Fahrassistenzsysteme
(Language: German)

Flüssigsilikon (LSR) Spritzguss ist eine geeignete Technologie für ADAS-Komponenten. Dieses Whitepaper vergleicht die wichtigsten Materialien und fokussiert sich dabei auf die Vorteile von LSR, sowohl material- wie auch prozesstechnisch.

LSR Technology Accelerating Advanced Driver Assistance Systems

Liquid Silicone Rubber (LSR) injection molding techonology lends itself to Advanced Driver Assistance Systems (ADAS) products. This whitepaper compares the main materials for sealing, damping and protection purposes and then focuses on the LSR benefits and processes.

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.

Reduce Vibration and Avoid Stiction in Seals
By Holger Jordan, fluid power segment
manager, Trelleborg Sealing Solutions 

Stick-slip is not always a big issue, but sometimes it can significantly
degrade performance. Potentially, it can cause damage, such as cracks in
steel work and strength loss, and even health problems for operators.

We look at solutions to combat
stick-slip to lower vibration as well as to create damping solutions.
Getting the sealing system team right
