Rubore® Design Guideline in Development

In addition to the information surrounding existing Rubore® products, a new guideline aims to simplify commissioning a new project that uses this advanced technology.

Trelleborg is developing a design guideline to ensure all the technical details are covered when it comes to initiating a new project that makes use of Rubore® products. Alongside specific information on the products and their manufacture, the guideline covers such aspects as the choice of materials, construction, mechanical properties and materials testing.Rubore Products

With regard to the latter, the guideline adopts a different approach depending on the type of product planned and its possible application. In the case of the Rubore® Frame Seal and Rubore® Cap Seal, for example, the testing is based on a single case study, with aging simulated by way of constant strain rate (CSR) and finite element analysis (FEA). FEA modeling is also used for testing the Rubore® Flat Seal and Rubore® Cover Seal, along with creep testing at various temperatures and pressures.

Depending on the intended use, further application tests are carried out on current live projects, and include thermal cycles, torque loss, and thermal shock. As a result, information is obtained on potential areas of application, structural design constraints and feasibility of the Rubore® products, compared to conventional sealing systems.
The guideline is a collaborative project involving several Trelleborg Sealing Solutions groups. R&D is coordinated by the product development in Fort Wayne, USA while the manufacturing details and expertise are the responsibility of Kalmar, Sweden. Trelleborg Sealing Solutions Stuttgart (R&D) is also supporting the project, and the AutoHub is in charge of contacting customers to realize application-based projects.
