Well-sealed doors and windows are important for more than just security. They improve a building's energy efficiency by keeping cool air in and limiting warm air entry during heat waves or draughts in the winter. If a door or window is properly sealed, it can keep out of a building dust, bugs, noise and unwanted substances, making it a clean, safe and comfortable environment.

For both residential and commercial use, door seals such as weather-stripping seals, door bottom seal brushes, and others are available. However, not all sealing materials are created equal.

The use of advanced materials such as thermoplastic elastomers (TPEs) to achieve the best results from good door seals is prevalent in the automotive, building, and construction industries, as well as a variety of other industries that manufacture sealing supplies and other products.

KRAIBURG TPE, a global TPE manufacturer of a diverse range of thermoplastic elastomer products and custom solutions for a variety of industries, provides high-quality and custom-engineered compounds with mechanical and physical properties suitable for door seals and other industrial applications.

EX series: a solution for indoor applications

KRAIBURG TPE’s EX series of compounds is suitable for the application of door seals and benefits manufacturers, not only in terms of cost efficiency, but also in terms of aesthetics, functionality, and design flexibility.

With good adhesion to PP and resistance to acrylic paints, it is developed for extrusion molding process, but can also be processed in injection molding process.

It is halogen-free (according to IEC 61249-2-21) and is alternative material to PVC-P. The series is available in black and natural colors, offers high thermal stability.

Furthermore, the compounds are recyclable within the production process and contain no latex, PVC, phthalates or added heavy metals.
